Thanks,
So if I understand this code, it appears to mean that the drivers side bank is running rich and the ECC is trying to compensate. Can someone help me prioritize my troubleshooting?
According to
www.obd-codes.com/trouble_codes/ford/p1151.php This condition can be caused by any, or several, of the following. I'd like to get an idea of which would be the most probable root cause.
Electrical:
* Short to VPWR in the harness or HO2S
* Water in the harness connector
* Open/shorted HO2S circuit
* Corrosion or poor mating terminals and wiring
* Damaged HO2S
* Damaged PCM
Fuel System:
* Excessive fuel pressure
Leaking/contaminated fuel injectors
Leaking fuel pressure regulator
Low fuel pressure or running out of fuel
Vapor recovery system
Induction System:
* Air leaks after the MAF
* Vacuum Leaks
PCV system:
* Improperly seated engine oil dipstick
EGR System:
* Leaking gasket
* Stuck EGR valve
* Leaking diaphragm or EVR
Base Engine:
* Oil overfill
* Cam Timing
* Cylinder compression
* Exhaust leaks before or near the HO2S(s)
