P0523
P0522
P0237
P0602
P1693
P0113
P0577
Help me out with all 11 of these *******! Thanks!

 

P1693 is a companion code. just means other codes are present.
P1682 - Charging system voltage too low
P0122 - APPS voltage too low (Accelerator Pedal Position Sensor)
P0500 - No vehicle speed sensor signal detected
P0523 - Oil Pressure Voltage too high
P0522 - Oil Pressure Voltage too low
P0237 - MAP sensor voltage too low
P0602 - ECM fueling calibration error - ECM internal fault condition detected
P0113 - Intake air temp sensor voltage too high
P0577 - Cruise control switch voltage too high



to me it sounds like either somebody is pulling a nasty prank and unplugged all of the sensors, OR you have bad grounds somewhere, OR the whole system doesn't have enough power to operate properly, or lastly and most likely the ECM is fried...

that is just way too many sensor codes which leads me to believe the sensors are fine and there is a huge electrical problem or the ECM is just dead.

 

Well it still runs fine.... starts right up and have no problems with going down the road... dont miss a beat
