Got a check engine light today - threw the following codes:

P1668
P1590
P1415

Anyone know what they are?

Found two...

Found them...

P1590 - ABS rough road signal circuit malfunction - Hardware is OK, but SLABS ECU is sending an error signal

P1668 Engine anti-theft signal circuit high - Serial link open circuit

P1415 Secondary air system fault bank

What would cause thes very different codes to go all at once?

did you in the past have a problem with the ABS sensors.

and did you pull the battery or set off the alarm or pull any fuses at all.


YOu might want to reset the codes and drive it one drive cycle basically ten miles at 55 MPh no cruise and three miles of city driving and two minutes of idling to reset all monitors. if the codes come back then it needs to be looked at by the code itself.

Alot of times on Rovers you end up reseting the light and test driving again to get a feel for what is actually wrong.

Thanks beezel. I just had one of the ABS sensors replaced two weeks ago. I have also been having issues trying to "arm" the alarm system via the key fob. Those are separate issues though, right?
