Looking for help with code p001685 saying left bank intake cam out of sync with crank or implausible. Have replaced chains gears and swapped sensors to no avail. Any help would be greatly appreciated
Need to look at cam and crank sensor with lab scope .to see wave pattern.
Was this code present before you did repair ? if so try reboot of ecu could be new cam n crank correlation not learned
Yes was there previous to repairs chain was extremely loose. Tried doing chain replacement teach in process . 3 of the 4 cams read about .5°-1.1° difference while the bank 1 intake cam is giving a -1476.01 difference. Could this be a actual camshaft issue?
Can you share cam and crank signals from scope, take a picture if you need to.
Just to let you guys know that the issue was the camshaft. The reluctor wheel had spun causing the code
