<TABLE border=1 cellSpacing=0 cellPadding=3><TBODY><TR><TD vAlign=top align=left>P0720 - Insufficient input from Output Shaft Speed sensor </TD><TD vAlign=top align=left>The output shaft speed sensor inputs a signal to the PCM, based on the speed of the output shaft of the transmission. The PCM compares this signal with the signal of the VSS or TCSS and determines correct tire size and axle gear ratio. </TD><TD vAlign=top align=left>
- OSS sensor circuit short to GND
- OSS sensor circuit short to PWR
- OSS sensor circuit open
- Damaged OSS sensor
- Damaged PCM

Hi Rickx
So you are saying that I should check the list of sensor problems you have listed and also how do I verify sensor output to speed. I did have one shop tell me that it could be a ground problem any idea where I should start and would a digram of speed sensor help also any idea where I could get one.
Thanks
