Major problems

[jimberg]

Bigred90gt,

Your codes are as follows:

KOEO:

22 - MAP/BP out of Self-Test range

In your case, it's BP (Barometric Pressure). This sensor is mounted to the firewall just to the left of the main vacuum tree. It helps measure the amount of air going to your engine. It's a critical component and should probably be replaced.


85 - Canister Purge (CANP) circuit failure

The canister is that black box behind the passenger side headlight. It's kind of under the air box. It is a charcoal canister that catches excess fuel vapor from the fuel tank and then releases it to the intake manifold to be burned.

Continuous Codes

22 - Same as above.

66 - Mass Air Flow sensor circuit below minimum voltage (Mass Air equipped cars only)

The MAF sensor isn't working correctly for some reason. I'd start with the BP sensor since it may be causing this code.

KOER:

12 - Cannot control RPM during Self-Test high RPM check

The idle air control solenoid (cylindrical thing on front of throttle body) is not working, or a result of the stall during the KOER test.

33 - Exhaust Gas Recirculation valve opening not detected (SONIC)

The computer tried to open the EGR valve and couldn't.

18 - SPOUT circuit open

The SPOUT connector is missing. It's a gray jumper that goes into a plug that is hanging off one of the wires that goes to the TFI module on the side of the distributor.
