- 1993 Explorer
Hey all,
My Mom has a 1993 ford explorer that has been running a bit rough of late. I jumpered the edc and got three codes; two saying the engine is running rich (one for left side and one code for right side), and one code saying the TPS was running at a low voltage.
I checked the wiring harness to the TPS with the KOEO and found that it is indeed running low with a voltage of 4.87 when it should be 5.0-5.1 +/- .1 volts.
If the TPS is getting low volts from the harness, 1: would that cause the engine to run rich? and 2: how do I fix the low voltage issue?
If it was the sensor itself I cold fix it easy enough with a replacement, but I have no clue when it comes to figuring out why the voltage coming into the sensor would be too low.
Any tid bits of info would be great! Thanks all.
