Code checking..

I ran a code tester on my car today, and with KOEO it threw MAP sensor, and O2 sensor. With KOER, it only threw EGR valve.

I guess my question is, are all 3 actually bad, or is something amiss?

It would be more helpful to post the actual code numbers. There are 02 codes for 1. lean, 2 for rich and 3 not switching. Also our cars use a BP senser, not a MAP sensor. 87-88 TC that have had the EGR recall done normally throw a 34 so letting us know what year car you have can also help

Sorry for the vague post, I didn't run the codes myself. But anyway, it's an 88 tc and the code numbers were

74, 72, 22

Sorry Pete, still getting used to all this. :x

72 = ECA power intrupt, open or short in power or ground. Might be electrical noise.

22 = BP sensor - check connector and wires at the sensor. Otherwise replace sensor

74 = BOO (brake on/off switch) shorted to ground

Were these continuous memory codes or "hard" KOEO codes? Did you have your foot on the brake or tap the brake during the KOEO test?
