My buddy has an 02 z06 w a magy supercharger on it. It is currently throwing a check engine code p 0140 and p 0157. Can anyone tell me what these mean and what is the typical cause of throwing them?


Thanks!

They're both rear 02 sensor codes it that helps. P0140 is insufficient activity, bank 1, sensor 2 - P0157 is low voltage, bank 2, sensor 2.

If he still has cats and rear 02 sensor's, then it is time to change them.

If he does not have Cats anymore, then he needs to have those codes tuned out.

Either way, these codes will not affect the way the car runs in any way
