I have 150 HP DFI 2001 optimax. The idle is about 3500 rpm. When i disconnect the TPS, the Idle is OK. I found a problem. On the connector of the TPS, We have 3 wire. one with 5 volts, one who send the modulated voltage to the ECM and one wire connected to the ground (Black/Orange).
On the ground wire (Black/Orange), I have 3.6 Volts and is not at the ground and isn't broken.Of course, the ECM read 87% of TPS. Someone can help me????
