Received a pip sensor failure fault code on my 94 f150. Also had all of the common signs like not restarting after its warmed up and randomly shutting off.
After replacing the sensor (motorcraft), all of my original problems are no longer acting up. However, today on a 4 hour trip home the CEL comes on and i pulled the same pip sensor code.
Any ideas as to why?
Battery has been disconnected several times. Egr, ac curcuit, and pip sensor fault.
List the codes by number and during which test they were displayed. Many times folks misinterpret the codes and chase their tails and spend money for no reason.
If you have a 4.9L engine you will get the AC circuit error if you did not push the clutch in during the KOEO test.
Try clearing the codes instead of disconnecting the battery.
Disconnecting the battery can set a code and should not be done unless you replaced a sensor but do not disconnect the battery for an actuator replacement.
After sensor replacement you need to disconnect the battery for 30 minutes and then clear the keep alive memory error code.
What is the codes you are getting? Maybe you are getting an IDM code with a 1994 and not the PIP sensor code. Also are the codes KOEO, CM or KOER codes?
You have 172 listed as a KOEO code but 172 is not a KOEO code. It is a code for DILUTED ENGINE OIL in CM or KOER codes.
I am not sure how a computer would know this one.
CM code 211 is a PIP sensor code.
Continuous Memory DTC 332 indicates the EGR valve did not open with the engine stabilized and the EVR solenoid duty cycle present sometime during vehicle operation.
DTC 332 in Key On Engine Running (KOER) indicates the EVP sensor input did not change after the EVR solenoid was instructed by the Powertrain Control Module (PCM) to open the EGR valve.
So I would think I would try a different PCM Computer.
Im using a innova code reader.I just found the book that came with it and it list 172 as a KOER or a Continuous memory code for H02S Sensor fault/lean. Is this correct?
Could be the right or rear H02S lean.
But it is under the heading of DILUTED ENGINE OIL.
Possible Causes:
-- Fuel injectors
-- HEGO sensor
-- Thermactor
-- PCV
-- Vacuum
-- CANP
-- MAP sensor
Wow thats a wide range of possible culprits. Seems like i would have a code for some sensor related to that!
How does the pcm monitor crankcase dilution?
