Car will give these codes and go into 'limp mode' run rough and die. Will not restart unless power removed from ECM to clear and codes will return within 5 miles run rough and die. Unable to clear with handheld code reader. Mechanic said O2 heaters and circuits fine. So I purchased refurbished 'plug and play' ECM from ebay. Got new codes P1189 & P1105 for TIP sensor and solenoid. TIP sensor is new so online company sent me 2nd ECM which gave new codes of P0700 & P0755- not communicating with Transmission and car would not shift from first gear. So online company sent me 3rd ECM which gave P0032 & P0038. They refunded ALL my money. Now purchased ECM from different online company and getting P0032.
What I have Done:
-Swapped ASD relay with horn relay.
-Unplugged Sensor 1 and measure 3.6 ohms heater resistance with no short to ground and only 9.5 Volt supply? Supply ground is good and Hot wire is 2.8 Ohms to ground?
-Unplugged sensor 2 and measure 4.3 ohms heater resistance and 10.7 Volt supply. Supply ground is good and Hot wire is open to ground.
Any assistance on my next step is greatly appreciated.
