1995 GMC pickup
My son took off the exhaust manifold without disconnecting the battery. The manifold fell onto the positive lead of the battery (right above the starter) and shorted to ground. I am now getting a OB1 error code of 34. (short, map sensor low voltage, ECM). I replaced the map sensor and checked for shorts. Could this of caused the ECM to go out?
