89 2.3 Manual CEL Codes 54, 67, 89

[bnunjo11]

These codes were taken KOEO and I would like to know a little bit more about them and how I should go about fixing them. I have tried looking into them myself and have seen that codes 67 and 89 don't exactly apply to a Foxbody Manual and are more meant for cars like an automatic Bronco, so i'm not sure how these pulled up.

Code 54 makes sense and from what i've seen the symptoms apply of having bad start ups in the cold and that sort of thing. However I am still unsure as to how I can fix this problem myself.

Any help would be appreciated

It looks like the intake air temperature sensor. This is either the sensor itself, a wiring issue, or (unlikely) an issue with the ECM.

67 you will get sometimes if you don't have the clutch down or if the car has a T5 swap with the incorrect harness or ecu.

are you 100% positive that the codes were read properly? It's not too terribly hard to get messed up while reading the CEL flashes.

89 is either an automatic trans code or a heat riser solenoid circuit failure. I am not sure on the heat riser but if you have an original 5 speed car with all the correct ecu and matching harnesses, you should not have code 89.
