J!m,
I'm resurrecting an old thread here, but I found it while searching. I've got an S52 swapped ti (engine and car are OBDII) with no secondary air pump currently installed. The CEL is on, but the only code I'm getting is P0135 which is for the o2 sensor heater circuit. Is there a separate code for the pump or does the pump's absence throw this code? I'm open to any suggestions. |
