Code 1351 After Timing Belt Replaced

07-24-2007, 08:33 PM
I have a 2002 Avalon XL with 113,000 miles. I just replaced the timing belt, water pump,tensioners & drive belts. After driving the vehicle for 15-20 miles the check engine light came on. The code was P1351 which indicates a malfunction with the cam shaft sensors. I checked wiring and located a disconnected ground wire. After reconnecting the wire and driving 7-10 miles the check engine light came on again indicating the same code P1351. I have never had a problem with the vehicle and the check engine light never came on until after the timing belt replacement. Does anyone have any suggestions? Thanks

Your timing belt is off by a few teeth. Either slipped (weak tensioner) or wasn't aligned properly with RH LH timing marks and #3 timing belt cover during the install.
