Bad VVT Solenoid Symptoms: 7 Common Failure Signs

Bad VVT Solenoid Symptoms: 7 Common Failure Signs
Discover the warning signs of faulty variable valve timing solenoids. This video examines the common bad variable camshaft timing solenoid failure symptoms - including check engine codes P0013, P0010, rattling timing chains, rough engine idle, oil leaks, hesitation on acceleration and loss of power. Learn how diagnose issues with your car's VVT Solenoid before major engine damage results.
A variable valve timing (VVT) solenoid is an electro-mechanical component that controls and adjusts the opening and closing timing of engine valves, primarily the intake and exhaust valves. The main failure signs of a faulty VVT solenoid in one paragraph are:
The VVT solenoid can fail over time leading to symptoms such as rough engine idle, loss of power, reduced fuel economy, engine misfires, check engine light illumination with trouble codes for cam/crank correlation or timing issues, engine oil leaks from a damaged solenoid seal, loud rattling noise from the valvetrain, and difficulty starting the engine due to improper valve timing. If these symptoms are observed, it typically indicates wear, clogging, or electrical failure in the VVT solenoid requiring replacement to restore proper valve timing control and engine performance.

I have a 2020 V6 Chevy Blazer outputting P0024 code. When shifting 1-3 gear she shakes. Runs very smooth after that. Could it be the selonoide?

[@acigaa1494]

I have a Mazda I tested my vvt with clips. I got either no click or rapid clicking. Probly bad? I read the Olms on it they where around 7.

[@giulianomacarrone7938]

Nice video! Mine is lealing oil extremely, should I replace it? Or just replace the O Ring and use sealer?

[@HonestMechanicChannel]

Thanks. depends on your budget, often times just replacing the seals works 100% but I personally recommend replacing the leaky VVT.

[@giulianomacarrone7938]

@@HonestMechanicChannel tnx, better not using the car and fixing it next month

[@anthony77morris]

If you go to a mechanic with this they will say you need new spark plugs because it will give the same symptoms. After they take your money for the tune up you didn’t need and the problem is still there, they will then charge you for diagnosis and finally they will replace the solenoid once they found the problem. This is how mechanics try to make extra money.

[@richardstar88]

Hi, when starting my Volkswagen Passat 2017, an error message sometimes appears. After taking it to the workshop for diagnostics, they mentioned that according to the computer, one of the electronic engine VVT components is faulty and needs replacement. Is this accurate? Appreciate for your input

[@HonestMechanicChannel]

Hi Richard, Apologies for the late response. what was the error message you got and was the car running rough?

[@commonsence8223]

I have an 08 tacoma 2.7l i4, i have had misfires and variable low idle/vibration, but if you give it a little gas, it runs good. I just got the haynes manual and read about this sensor. I was going to pull the head and have it checked. Do you think it might be this vvt sensor?

[@HonestMechanicChannel]

Given the symptoms you're describing with your 2008 Toyota Tacoma 2.7L I4 - misfires and variable low idle along with vibration that improves when giving it gas - it is indeed plausible that the issue could be related to the Variable Valve Timing (VVT) sensor, especially since VVT plays a crucial role in engine timing and performance. The VVT system adjusts the timing of the camshafts to optimize engine performance and efficiency. If the VVT sensor (often referred to as the VVT solenoid) is malfunctioning, it could cause the timing to be off, leading to misfires and rough idling. Before you consider pulling the head, which can be quite labor-intensive and expensive.

I have a 2013 lexus is250 75k miles, it rattles for 2 seconds when starting after being idle for a while. Could it a vvt solenoid ?

[@HonestMechanicChannel]

Hi, way to go for choosing a Lexus!. It sounds like your Lexus IS250 might indeed be experiencing a problem related to the Variable Valve Timing (VVT) system, particularly the VVT solenoid. The rattle you're hearing upon startup, which dissipates after a couple of seconds, could be due to the VVT solenoid failing to properly control the flow of oil to the VVT chain on initial startup. This is relatively common in vehicles as they age and accumulate mileage.

[@patrickmurphy8619]

I saw your comment. That's a bad tensioner. So what happens is oil leaks out of the tensioner when the car sits and the change loose when you start it and it rebuilts pressure

[@magnificentkwilliard3214]

Yo my man, quick question ❓ will these being bad make a car backfire and rPmZ not to work all of a sudden after changing starter, oil, manifold intake just minutes ago or “NO “

[@HonestMechanicChannel]

Hey man, managed to get it sorted? Yes, faulty VVT solenoids can potentially cause backfiring and RPM issues, as they affect engine timing. However, if these problems started right after changing the starter, oil, and intake manifold, it's also worth double-checking those areas for any installation errors or disconnected sensors.

[@magnificentkwilliard3214]

How about after all those changes there my man and still no change, it’s LOW ENGINE COMPRESSION and it’ll be going to the shop nDa morning to get engine #3️⃣, all sensors from 0², crankshaft, both camshafts, VvTs,plugs, coils all.,.smh 🤣😂🤨,Ecotec motors are weak but I thank you a million dude

[@aciddiver1978]

Hi. My car sometimes rattles 1-2 seconds after startup. Its not got timing chain. Can it be vvt solenoids? Will it damage something if not replaced? No fault codes are present, and no other symptoms.

[@HonestMechanicChannel]

Hi. Yes it could be related to the solenoids. If the VVT solenoids are failing or are clogged, it's possible that you won't see immediate fault codes or other symptoms but experience some rattles. But since its only 1-2 seconds after startup, I wouldn't be worried just yet.

[@aciddiver1978]

​@@HonestMechanicChannelthank you for the answer. I love this channel😊

[@HonestMechanicChannel]

Thanks, I really appreciate your support mate!

[@openwidesky]

While this is a common problem in cars with high mileage it's better to scan the ECU for codes rather than looking for symptoms to identify a problem. Rough idling, misfires, poor starts and other symptoms could be caused by other conditions. Many DIYs jump to conclusions and end up ' fixing' things that had nothing to do with the problem. Most VVT failures usually result from dirty screens which in turn are the result of irregular oil change intervals. If a VVT code is present, remove the valves ( intake and exhaust) and clean the screens with a solvent such as brake cleaner. If that doesn't solve the problem then replace the vvts. Symptoms are only a ball park approach to a problem that can tell you which components to check. For an accurate diagnosis identify the part that is failing. This will save time, money and frustration.

[@shahaidilabrahman5291]

is the engine oil light blinking while driving relate to this solenoid?

[@knockoff9580]

Hello, I have a 07 Nissan Altima and upon start up, the car shakes, on warm up under acceleration it makes a ticking noise 1.5k rpm to rev limit could it be a vvt solenoid or a piston, rings, or something else?

[@HonestMechanicChannel]

The shaking on startup and ticking noise during acceleration could be caused by several issues, such as: 1. Faulty VVT solenoid 2. Low oil level or poor oil quality 3. Worn valve lifters or camshaft lobes 4. Exhaust manifold leak 5. Spark plug or ignition coil issues While worn piston rings are a possibility, they are less likely to cause the specific symptoms you described. It's best to have a mechanic diagnose the problem to determine the exact cause and appropriate repair.

[@naeemallaway8040]

Hi, had a bearing Knock on my audi, cut the crank, replaced pistons, rings, bearings, schemed the head replaced valves on cylinder 3 and i still keep getting misfire on cylinder 3, the compression in the cylinder is quite low but its low on cylinder 2 and 4 as well, but only getting the misfire on cylinder 3 on the VCDS and high values for misfiring on cylinder 3, could the VVT cause this as its strange that only cylinder 3 is misfiring so much, also the misfire is mostly at low rpms, some help would be appreciated.

[@HonestMechanicChannel]

Hi Naeem, did you manage to find the cause?. A bad VVT solenoid can cause that especially on Audi's but my hunch tells me you might have a bad fuel injector on cylinder 3.

[@EdgarInter]

Hi i have a toyota vitz 13 vvti and the vvti is not working can it be the solenoid ?

[@HonestMechanicChannel]

Hi, Yes, a common issue with the VVT-i system not working in a Toyota Vitz 1.3 VVT-i could indeed be the solenoid. The VVT-i solenoid controls oil flow to adjust the timing of the camshaft for optimal engine performance. If it's faulty or clogged, it can prevent the VVT-i system from functioning properly. It's advisable to check the solenoid for any signs of oil blockage or electrical issues.

[@Invisible2958]

I have a 2006 Nissan maxima I can drive it for 30 minutes fine at whatever rpm I want but after 30min my car will not go up 3k rpm on all my gears and the car want to die and the rpm go up and down when I’m idle and driving could it be the vvt solenoid or timing chain skipping teeth ?

[@HonestMechanicChannel]

Hi, Your issue, where the car operates normally for 30 minutes before experiencing RPM limitations and instability, could potentially be related to the VVT solenoid, but it might also involve other factors such as fuel delivery problems, a clogged catalytic converter, or an issue with the engine's electronic control system, including sensors like the MAF or O2 sensors. While a timing chain skipping teeth is possible, it's less likely to cause intermittent problems and would typically result in more constant and severe running issues or the engine not running at all. Before focusing on the VVT solenoid or timing chain, consider having the vehicle's computer scanned for trouble codes and checking for any issues with fuel pressure or exhaust flow restrictions.

You never mentioned to check for ground , or ohms , or voltage ??????😢😢😮

[@ChrisBrown-xq8ji]

I have a 2019 Infiniti Q50 3.0t (94K miles). My car was driving very sluggish when I was trying to accelerate. Does this has anything to do with my catalytic converter? I ran my OBD scanner and got the two codes: P0012 - A Camshaft Position Timing Over - Retarded Bank 1 P0022 - A Camshaft Position Timing Over - Retarded Bank 2

[@HonestMechanicChannel]

Hi, The sluggish acceleration and the diagnostic trouble codes P0012 and P0022 are related to the variable valve timing (VVT) system, not the catalytic converter. These codes indicate that the camshaft timing is retarded (delayed) on both banks of the engine. This issue can cause reduced engine performance and sluggish acceleration. I would first check the cam position sensors then move to vvt solenoids

[@glentreasure2466]

My car runs great cause everything great stays on the number one on tachometer oil is great. A problem little tap and up by the camp shop phaser results back.

[@HonestMechanicChannel]

It sounds like you're saying your car generally runs well because all the indicators (like oil pressure) are in the optimal range on your dashboard. However, you're experiencing a slight issue, possibly a tapping noise, which was diagnosed at a repair shop as related to the camshaft phaser. This component helps improve the engine's efficiency by adjusting the timing of the camshaft. If it's faulty, it might need repair or replacement to resolve the noise and ensure your engine runs smoothly.

[@jamalcelestin2386]

I’m getting p0014 on my 3.0t q50 can it still be my vvt

[@HonestMechanicChannel]

Hi, Yes since it is a cam related code, most likely the VVT. let me know how it goes

[@tommyd6665]

What if I get a P0011?

[@HonestMechanicChannel]

P0011 is a diagnostic trouble code (DTC) that indicates a timing issue related to the "A" camshaft on bank 1 of the engine. The code description is "Intake Camshaft Position Timing - Over-Advanced (Bank 1)". This means that the intake camshaft on bank 1 is more advanced than the ECU expects it to be. Possible causes for this code include: 1. Low engine oil level or dirty oil 2. Stretched or jumped timing chain 3. Faulty camshaft phaser or actuator 4. Camshaft position sensor issue 5. Sludge or debris in the oil passages 6. Wiring issues or damaged connectors related to the camshaft position sensor or actuator In rare cases, a faulty ECU

My 15 rogue runs great at start up, after warmed up it vibrates at idle .. no check engine light, however scanner says vvt monitor bank 1 status fail .. what could that be ?

[@HonestMechanicChannel]

Hi, suggests a possible issue with the Variable Valve Timing (VVT) system. The VVT system is designed to improve engine performance and efficiency by altering the timing of the valve opening and closing. Here are a few possibilities (Most common to least) 1. VVT Solenoid or Actuator Problem: The VVT solenoid controls the flow of oil to the VVT chain and gears. If it's malfunctioning or clogged, it can affect the timing, leading to rough idling. 2. Oil Quality and Level: Low or dirty oil can negatively impact the VVT system. Since VVT relies on hydraulic pressure (which comes from the engine oil), insufficient or contaminated oil could hinder its operation. 3. Timing Chain or Belt Issue: If your Rogue uses a timing chain (which is more likely) and it's stretched or not functioning correctly, it could affect the VVT system.

[@johnf.6942]

@@HonestMechanicChannel Thank you ! I’m thinking the chain stretched since I change oil every 3,000 miles, I would think the solenoids would be ok with that interval, and chain for that matter. The car is at 77,800 miles the chain shouldn’t be an issue yet , but I guess could be. I don’t have the facility to do it myself, now I have to find a reputable mechanic who will be honest about what it really needs.
