Appreciate all of the help. Mechanic is suggesting it is a $400+ repair ($80 parts/ 330+ in labor), because of the location of the sensor. It seems really expensive, but I know little about this.
The estimate states:
REPORT: Diagnostic Trouble Code PO340 ( camshaft position sensor malfunction )
stored. Tested output of cam sensor, no output, needs replacement.
REPAIR: Remove engine accessory belts and timing cover. Remove and replace the cam
posistion sensor. Clear fault code. Road test to run monitors to verify repair.
I was curious about all of this because it seems frustrating that after shelling out money to fix an engine, days later a sensor goes bad, and the cost to replace is extraordinary.
Its incredibly frustrating because despite there being a warranty on the engine, there is no way to prove that the sensor they used was originally mine, or replaced in the swap. I am not sure if that is something that is common, and I guess frankly I have to go based on their word.
In regards to George’s questions, as far as I know, it was an exact d17 2005 engine replacement. It wasn’t a factory rebuilt engine, or even performed by a dealer.
I feel like it is just horrific luck, but figured I would check regardless.
Again, I appreciate your help. I trust these guys, but unfortunately, when things are this expensive, I tend to double check everything.
