1ZZFE Toyota Corolla Variable Valve Timing Solenoid and Oil Filter 9th Gen

[@MarzNet256]

Really excellent trick with the clip to get the filter out. You can also get needle nose pliers with a 90 deg bend at the tips. I also had a rough idle and pending lean code. Turned out slow oil leak from valve cover contaminated electrical connector on drivers side of engine block (crankshaft position sensor). This caused ECU to get bad data and try to compensate, resulting in lean condition. Cleaned connections, problem solved. Replaced valve cover gasket. 2006 Matrix with 152k mi.

[@delotrolado1]

The last part of the video when you zoom inside were vvt selenoid goes is what I have been looking for hours. Thanks for the close up.

[@akhilmuraleedhar]

My 08 corolla had very rough cold starts. The whole car vibrates at start up. The issue was with the throttle body and MAF sensor. Got it cleaned. Works real smooth now.

[@cluelessguy1754]

I also got those cleaned twice and made no difference in the dipping rpm when coming to a stop.

[@Xanderfied]

Could also be the vvt sprocket needs replacing

[@akhilmuraleedhar]

The throttle body was cleaned in place. Using WD 40. MAF sensor was cleaned with MAF quick drying spray. I clean these two every month along with the air filter. The kmpl increased from 8- 14 after doing these for the first time in months.

@@cluelessguy1754 You probably need a new intake manifold gasket. If it gets worse as it get colder outside that might be it. Also, using scan tool, check output of coolant temperature sensor to make sure it is reading correctly.

Oh brilliant! I was only this morning asking myself "where IS the filter for that solenoid I pulled..." Thank you!

[@shertalk1528]

I had a Yaris 2009 2NZ-FE 1.33 liter. Had exact same problem as you. After cleaning injectors, changing sparks and throttle body cleaning, nothing helped. Changing the solenoid did finally do the trick. My buddy mechanic told me it's 50/50 chance once you get the solenoid out that it might break and need replacement immediately. Long story short, it did fix the problem and I love your video. (FYI, I had the same milage as you lol)

If I remember correctly, replacing the pcv under the intake manifold solved this issue on my 10th gen.

This is caused by intake manifold gasket being worn or damaged. If you replace it the gasket, make sure the gasket is assembled perfectly.

Exactly. Toyota upgraded the intake valve gasket due to issues. I agree this would cause a vacuum leak and rough idle. 👍

I sold the car soon after I made this video. I wasn't able to completely solve the problem. And yes, I would think that the variable valve solenoid not getting the oil pressure it needs would cause misfiring since the valves aren't opening and closing the exact time they need.

Hi, have you ever found a solution? I have a Toyota Avensis 2008 with this engine 1zz-fe and the same problems that you say, mostly erratic and hard idle. I have made more or less the same diagnostics as you without result. But once I tried a fuel additive to clean the system and while that fuel tank lasted mixed with the aditive, the car run much much better. I think it might be related to the o2 sensor.

[@cluelessguy1754]

I no longer have the car but no, i wasn't able to fix it. I did replace both oxygen sensors and it didnt make a difference. And a new catalytic converter and MAF sensor didnt fix it either. I have a fuel injector cleaning kit and cleaned the injectors while they were in the car. I didn't notice any difference. One thing i was going to try if i still had the car would be to remove the injectors and either clean or replace them. I did use a scope on them and the readings were good, so they werent sticking. But there is no way to tell if they were partially clogged or even leaking without removing them.

Correct if you had a car with cable throttle. Some research into this points to a few different things. Air leaks at the intake manifold, tired MAF and tired O2 sensor are some other potential causes. But it may very well be an ECU issue in how they mapped it as well.

Drive by wire started in 2005, so no IAC valve.

[@TommyboyGTP]

What was the update on this?

[@cluelessguy1754]

I no longer have the car but this by itself did not fix the low idle. It's my opinion that the low idle is a result of a compilation of things like the filter I cleaned, the variable valve solenoid, throttle body, spark plugs, oil condition, battery/alternator condition and the condition of negative and positive cables to and from the battery to the engine and the cars body, PCV valve and MAF sensor.
