Ford Taurus Problem Report
Ford Taurus code 340 cam sensor
code 340 and after replacing the cam sensor and sync assembly, the code still exists. with all readings normal, scope pattern of the cam sensor are ok, the code remains due to a faulty DPFE triggering the code. Ford is aware of this issue and has no fix available for this issue. care needs to be taken when diagnosing this issue as to not replace parts that are, in fact, still good. We have tried re flashing the PCM with negative results. Roy - mastertech6371
code says primary and secondary coil failure, checked all wiring from coil to PCM(all OK) coils...
02 sensor 1 & 2 bad how do you know where 1 & 2 are located
Replaced EGR, EGR solenoid, and EGR pressure sensor. Code still returns. Any ideas what would cause this?
