go4par Posted March 7, 2020 Share Posted March 7, 2020 My 2001 Lexus RX 300 had over 235,000 miles now. Previously replaced the timing belt by dealer on 110,000 mile then I drove 125,000 miles. This time I replaced the timing belt and water pump myself then I have CEL P1346. Engine runs fine but CEL .Code scanner saying VVT sensor/camshaft position sensor circuit range /performance problem bank 1. I replaced both VVT solenoids that didn't help. I am sure I installed it correctly but want to know what causing the triggered the cel turned on. Anybody had any idea? Quote Link to comment Share on other sites More sharing options...
LEX200108 Posted September 2, 2021 Share Posted September 2, 2021 I know this is an old post, but it appears the timing belt is off a tooth. Quote Link to comment Share on other sites More sharing options...
