Have a 1991 Mustang Lx2.3l. When I do koeo test I get code 122. Tps sensor is brand new. Just replaced. Went ahead with koer test and got codes 998 and 122. Need help in the direction I should go.
When I tested my tps sensor I was getting a constant reading of 0.051 volts. Something turned on and the voltage went to 0.124 volts. No change when going to wide open throttle. Could the map sensor be messing with the numbers I saw they share a wire on a diagram. Honestly dont know what I'm looking at.
