Customers car listed above. Customer stated, Check Engine Light was flashing and took the car to AutoZone to have checked. Then had me replace knock sensor.
I erased a p1326, and the same pending, but it said there was a p1326 permanently stored, which I could not erase.
Upon starting the engine (with the new sensor), I thought I could hear a knock - especially between 2,000 and 3,000 RPMs. The customer then decided to tell me that the sound was there the whole time (after repeated conversations of how the knock sensor works, which I don't know why he wouldn't give me that info then).
The Check Engine Light is back on after a 15-minute drive. customer says knock kind of went away.
So, if this were a rod knock, wouldn't it have been always there, not just intermittent?
I have the old knock sensor; is there a way I can check it to see if it was operating correctly?
Thanks for any and all ideas.
