So last night went out and left the car out for about 5 hours. Temps weren't especially cold (about -25F) and when I got back in here is what happened:
1) Initial start was sluggish
2) Variable Intake motors (a known problem) CEL was on
3) EPC came on and car nearly died. Luckily I wasn't far from home and so I limped back at around 20 mph with no power.
4) CEL light began flashing furiously and then was a steady ON as the engine warmed a little
5) Having parked the vehicle overnight in the garage, I dumped the log and cleared the codes, hoping the cozy 58F in the garage would help.
6) Variable intake motor error codes cleared but EPC reappeared:
Mode 03: Emission related fault codes
Address 7E8: 09 Faults Found:
P129C - Manufacturer specific code
P2257 - Secondary Air Injection Pump Relay (J299): Short to Ground
P0102 - Mass Air Flow Sensor (G70): Signal too Low
P010C - Mass Air Flow Sensor (G246): Signal too Low
P0031 - Oxygen (Lambda) Sensor B1 S1: Heating Circuit: Short to Ground
P0051 - Oxygen (Lambda) Sensor B2 S1: Heating Circuit: Short to Ground
P2401 - EVAP Leak Detection Pump Control Circuit: Short to GND
P0037 - Oxygen (Lambda) Sensor B1 S2: Heating Circuit: Short to Ground
P0057 - Oxygen (Lambda) Sensor B2 S2: Heating Circuit: Short to Ground
It didn't snow so there's nothing wet.
Not sure what is meant by some members reported that they can shift without using the brakes, but I doubt the brake controller is it as it would not trigger the above. But one never knows...
Any thoughts???????
