Issues with Crank Position relearn Went to try and get my crank position relearn done today but couldn't get anything accomplished. The car was reading that it was doing 1-2MPH when revved when it clearly isn't moving. LoL. Unplugged the VSS to kill all signal and it still could not run the relearn. I'm assuming it might be becaus ethe PCM doesn't know the car is in "Park" as I don't have a late model park/neutral position switch hooked up. Is this needed or do I have another problem elsewhere? Failry frustrated with this.

IIRC, the crank relearn requires:
vehicle speed = 0
engine temp > 150* F and < 220* F
RPM < 2400 before starting relearn
Transmission in park (A4) or nuetral (M6)
vehicle speed = 0
engine temp > 150* F and < 220* F
RPM < 2400 before starting relearn
Transmission in park (A4) or nuetral (M6)
The following DTC's will prevent a relearn:
•
P0336 Crankshaft Position (CKP) Sensor A Performance
• P0341 Camshaft Position (CMP) Sensor Performance Bank 1 Sensor A
• P0342 Camshaft Position (CMP) Sensor Circuit Low Bank 1 Sensor A
• P0343 Camshaft Position (CMP) Sensor Circuit High Bank 1 Sensor A
• P0117 Engine Coolant Temperature (ECT) Sensor Circuit Low
• P0118 Engine Coolant Temperature (ECT) Sensor Circuit High
• P1539 Air Conditioning (A/C) Clutch Feedback Circuit High Voltage
• P1546 Air Conditioning (A/C) Clutch Feedback Circuit Open
• P0705 Transmission Range (TR) Switch Circuit
• P0706 Transmission Range (TR) Switch Performance
• P1810 Transmission Fluid Pressure (TFP) Position Switch Circuit
• P1825 Internal Mode Switch-Invalid Range
• P0341 Camshaft Position (CMP) Sensor Performance Bank 1 Sensor A
• P0342 Camshaft Position (CMP) Sensor Circuit Low Bank 1 Sensor A
• P0343 Camshaft Position (CMP) Sensor Circuit High Bank 1 Sensor A
• P0117 Engine Coolant Temperature (ECT) Sensor Circuit Low
• P0118 Engine Coolant Temperature (ECT) Sensor Circuit High
• P1539 Air Conditioning (A/C) Clutch Feedback Circuit High Voltage
• P1546 Air Conditioning (A/C) Clutch Feedback Circuit Open
• P0705 Transmission Range (TR) Switch Circuit
• P0706 Transmission Range (TR) Switch Performance
• P1810 Transmission Fluid Pressure (TFP) Position Switch Circuit
• P1825 Internal Mode Switch-Invalid Range

Hmmm! P1546 might be causing it then. I almost have the complete A/C setup done but havent wired it up yet. Will P1546 throw a MIL? Would it show up on a regular cheap scanner?
