I have been diagnosing an error code 332 problem on my 95 f150 xl (302 motor, 2 wheel drive) and I believe I have narrowed the problem down to the PCM. I have replaced the egr sensor and have verified that the egr valve is operating by bypassing the solenoid and applying vacuum dirrectly to the egr valve. This results in a immediate bogging down of the engine. My next thought was that the solenoid was bad so I checked for the 20 -70 ohms across the solenoid, this checked out ok. I checked the resistance of the circuit between the solenoid and pin 33 on the pcm and this was less than 1 ohm. I checked that resistance between pin 33 and 37 on the pcm, this returned a reading of 105 K ohms (105 on the 200K range of the multimeter). According to a previous reply on the ford.justanswer website if the resistance value between pin 33 and 37 exceeds 10,000 ohms then the pcm is defective. I also checked the resistance between pin 33 and 57, 33 and 40, 33 and 46, and , 33 and 60. All these checks gave close to the same reading of 105 K ohms.
I now have the pcm off the truck and am wondering if I could bench test the resistance values directly on the pcm as a double check. I do not have a breakout box so the previous checks were done with the pcm connected and I pierced the wires with thin needles to get the resistance readings. So if I measure the resistance between pins 33 and 37 directly on the pcm, while off the truck, and receive the same values as before will this verify that the pcm needs to be replaced. Thanks.
