This is my first post. Okay, I am AMAZED and, frankly, overwhelmed, at everything on this forum.
If any of you can help me pin point what's wrong, I'd appreciate the help.
I knew it wouldn't last. Last September, I did some emission control system repairs on my 1993 Explorer so I could pass my emissions test and register my car. Now, a few months later, I've got a "Check Engine" light. I pulled the codes using a code reader. These are KOEO codes. They are as follows.
186 - fault in injector pulse width circuit/high
332 - insufficient EGR flow detected
335 - EGR sensor circuit voltage higher or lower than expected during self test
336 - EGR sensor circuit voltage higher than expected
336 - (Trucks only) exhaust pressure high
337 - EGR sensor circuit above maximum voltage
As most codes point to the EGR system, let me state that the EGR solenoid, EGR valve, Pressure Feedback Sensor (PFE) and PCV valve are all brand new. The oxygen sensors are new and the catalytic converter is only two years old.
Is this a case of the replacement component failing early on? Perhaps the new EGR valve died?
Truck is 20 years old with 110k miles.
It is running just fine but that light,...
