I followed your procedures for replacing transmission external oil filter, cleaning throttle body, and idle relearn on my wife’s 2011 Civic EXL-Navi Coupe. It was real easy and the car runs great now. Thanks so much for posting these videos.

[@vicentepeluso5565]

Hi, nice video. I keep having issue with unstable rpm specially on first start. Rpm goes up and down. Scanner throws P2135 and P0108, any help please?

[@dannysdiygarage]

error codes P0108 and P2135 are most commonly associated with issues related to the mass airflow sensor (MAF) and throttle position sensor (TPS) in a Honda Civic. Here's a breakdown of each code: P0108: Meaning: Mass Airflow Sensor Circuit Low Voltage Possible Causes: MAF sensor failure Wiring or connector issue Engine vacuum leak Air filter restriction Symptoms: Reduced engine power Rough idle Increased fuel consumption Check engine light illuminated P2135: Meaning: Throttle Position Sensor Circuit 1 Malfunction Possible Causes: TPS sensor failure Wiring or connector issue Throttle body issues (stuck, dirty, or damaged) Symptoms: Reduced engine power Rough idle Driveability issues Check engine light illuminated Addressing the Codes: Gather Information: Check the vehicle's service history for any related repairs or issues. Inspect the MAF and TPS sensors for any visible damage or corrosion. Check the wiring and connectors for any signs of wear or damage. Diagnostic Testing: Use an OBD-II scanner to retrieve specific data related to the MAF and TPS sensors. Compare the sensor readings to the manufacturer's specifications. Perform a visual inspection of the engine for any vacuum leaks or air filter restrictions. Repair or Replacement: If the MAF or TPS sensor is found to be faulty, it will need to be replaced. If there are any wiring or connector issues, they will need to be repaired or replaced. If a vacuum leak or air filter restriction is identified, it will need to be addressed. Additional Tips: Always consult a qualified mechanic or technician for a proper diagnosis and repair. Avoid driving the vehicle with these codes present, as it can lead to further damage or safety issues. Consider using high-quality replacement parts to ensure long-term reliability.

Hi Danny, TYSM for these videos. Will this procedure help when the idle seems to "surge" when the AC is turned on and the compressor kicks on? Or is that a different problem?

[@dannysdiygarage]

Yes, that's pretty much what it's for

[@AlecFacemire]

So this will help if your idle surges sometimes and the car cuts out ever so often

[@ml-fishing1341]

What if your idle is ‘hunting’ and after cleaning all intake and throttle body, including map and maf. Also says map voltage high when I scan with bluedriver but no CEL

[@frankvarela8520]

I did this procedure twice. And my fan didn't come on at all. But I do know the fans work. Because when I turn on my ac. The fans will run then.

[@immanueljones4950]

Is this process the same for hybrid ?

[@likkaweyy]

Hey Danny. I cleaned my MAF And MAP sensors on my 2012 civic and it’s idling high in the 2/3K RPMS. Does it need a idle relearn procedure if so can I use this method..

[@dannysdiygarage]

Yes do a idle relearn,what did you use to clean your sensor

[@dannysdiygarage]

Also recheck your work, sounds like you might have a vacuum leak

I have a question in my 2007 civic fd manual. My idle normal rpm is 800, and when I sped up like 40mph then putted the gear into neutral, my rom stays at 1.4k stable until I fully stop. I’m on neutral and I’m not stepping up the gas but my idle stays at 1.4k while the car is moving. And also, then I let go of the gas, my rpm goes up first like around 2k rpm before it goes down to 800rpm. What should I do?

[@dannysdiygarage]

Hard to give advice when you can’t check the car, but, Start by cleaning throttle body, do a reset and relearn, if your car has a throttle cable check the idle air control valve

Hi Danny. Thanks for the video post. My 2008 Civic GX only idles poorly in the morning, and when it is below 70 or so degrees. I have to let it idle for 5-7 minutes and it sputters, which can be heard at the exhaust pipe. I then have to shut the car off and start it again. The sputter stops and I can drive the car. The check engine light flashes when I first start it. If I don't warm it up, the engine rpm won't go past 1500 rpm and its impossible to drive the car. It also throws the 302 misfire code for the number 2 cylinder. Will this reset help or is there something else that is causing the problem that you can suggest a repair for?
