I have the following codes popping up all of a sudden-here is the LONG list:

ENGINE
P1491-Rad fan relay circuit
P0132-02 Sensor B1 Sensor
P0135-02 Sensor heater
P0138-02 Sensor B1 Sensor
P0645-AC Clutch relay circuit
P1282-Fuel Pump relay circuit
P1491-Radiator fan circuit
P1687-No mechanical instrument cluster

OBD II

P0123-Throttle Position sensor
P0443-Evap emmision system purge control valve circuit
P1491-Manufactured controlled aux emmision controls

I have recently changed both O2 sensors (1000 miles ago).

I am wondering if anyone has any ideas if one thing might be causing this like a bad ground or bare wire or if it is ten differnt things . Any help would be appreciated. Thanks in advance.........

I would make sure your O2 sensor leads haven't melted to the manifold/header. I can assure you, all of those things didn't coincidentally go bad overnight. There is a root cause.

 

Yeah, something had to fail for all of that to pop, troubleshooting may take a while.....I will check the O2 sensors for damage.

 

Problem SOLVED! Stupid U-haul wiring. Whoever dropped it in did a crap job, ALL the codes cleared. Amazing, one wire grounding out caused all that problem. On to tow hooks and a 2 inch lift!
