Customer Question

Hi Dave, I'm a 30 plus year tech, seen a lot of changes, I suspect I'm fighting a programing issue but need your experienced advice to confirm. I'm trying to diagnose a code po 501 on a 08 spectra,with out abs. Vehicle in air,all codes cleared, hooked up with wireless scan tool, engine running, transmittion in drive, speedometer at 12 mph, scan tool says its at 0, input shaft sensor reading 591, third gear reading on shift selection ,output sensor reading 591 +_, the scan of 0 speed doesn't match what I'm seeing at the speedometer. I'm guessing, that the input shaft sensor and out put shaft sensors are functioning correctly and that the computer is processing the info correctly to enable the instrument cluster to consistently give accurate mileage readings. I'm lost as to why I'm getting a zero mph reading at my scan tool , but believe this to be the reason for the po 501 please advise

Hello and thank you for your question,

Are you sure you do not have ABS, dose the right front wheel have a speed sensor?
