I have a 1995 Chevy pickup 4 X 4, 350 engine, 200,000 miles; the service engine light comes on sporadically, code 33 and 52, Replaced the MAP sensor and the code 33 went away, so I just get code 52. The manual I have indicates “PCM detects ignition feed voltage greater than 16-volts for 90-min", but the manual also makes a reference to codes (52 and 53) “represent internal transmission problems", I have a standard transmission.
The light comes on when I first start up the truck, not in 90 min, this includes when I clear the codes. It also comes on and off after awhile, and then will come back on.
Any help trying to figure this out would be appreciated, what should be checked and how to check it would be appreciated?
have the same problem?
