The check light comes on with code P1346 which means Variable valve timing sensor/Camshaft position sensor circuit range performance Blank 1. I have changed the cam sensor and the VVT sensor and the light still comes back. Car runs excellent.Light comes on a few minutes after driving, if you shut off the engine and restart it the light goes out but comes on back. Toyota ipsum 2002.
This is a code for variable valve timing sensor circuit range performance. possible causes are timing chain stretched or jumped timing causing a correlation difference between the can shaft signal and the crank shaft signal, if timing components are good then it might be a bad engine control module.

The VVT-i will outperform a car without it. ANY car with variable valve timing is a PLUS. Under hard acceleration, the duration of the valve opening timing changes, this results in a bit more power. Then, at idle.easy acceleratin, they change again. They continously change, depending on your driving...it "Learns", your driving...that is the " i " part in VVT-i.
Varible Valve TIming (with) intelligence". It's a good thing.
A FixYa rating would be most appreciated.

Idle is factory set and cannot be adjusted, your best bet is checking for cracked hose pipework for air intake at idle,(not at problem under exceleration and driving) Any slight upset to the air /fuel ratio will be most prevelent at idle speeds.Check hoses where the meet metal flanges on manifold intakes and any sharp bends in ppipes.Good luck

Yes all terminals were clean,and all the wires are ok.
Yes we clean off the terminals and the wires seems to be ok.
did you clean off all terminals when you installed the new sensors? make sure that the wires are not yanked out of plug.
