Transmission Control Unit/Module(TCU/TCM) for Honda models 1992-1994, were made with faulty components. I knew mine was bad, not only through my research efforts, but also because I took the TCU completely apart so that I could visually inspect the circuit board. That was when I discovered a burnt spot on one of the components. The Transmission Control Module is located under the carpeting of the floorboard on the passenger side. First disconn...

The Powertrain Control Module (PCM) can misinterpret data from the coolant temperature sensor and set a false Check Engine (MIL) light. The PCM will need a software update for this issue.
On certain models, a transmission solenoid can short-circuit and illuminate the Check Engine Light.
The computer can misinterpret a low battery voltage and can cause a false Check Engine (MIL) light to come on. Updating the PCM can correct this issue.
The PCM can misinterpret data from the air fuel sensor and set a false Check Engine (MIL) light requiring a PCM update to repair.
The AC condenser failed due to contact with road debris and a lack of protection for the condenser.
A Check Engine Light can come on because some models may misinterpret the ratio of air and fuel being burned for combustion. The powertrain control module (PCM) will need to be replaced to fix the problem.
Some models can have a problem with moisture entering the fuel pressure regulator and affecting the amount of fuel being burned in combustion. This would set a Check Engine Light.
Contamination can get in the distributor, cause a misfire and set a Check Engine light.
