No. The ECM is a computer.
Yes, a faulty Engine Control Module (ECM) can cause an air conditioner to blow hot air. The ECM regulates various functions in the vehicle, including the operation of the A/C system. If it malfunctions, it may not properly control the A/C compressor or other related components, leading to insufficient cooling and hot air being circulated. Additionally, issues with sensors that the ECM relies on can also contribute to this problem.
I have a V6 and the ECM was a pain to get to: 1) remove the glovebox 2) remove the blower for the air conditioner/fan 3) lift the carpet under the blower 4) and there it was.
It can.
Bad ecm
No you can not , That is what makes and keeps the engine running
dont know about the emissions stuff but if your planning to swap engines the ECM will also have to be switched as the 267 ECM will not work on the 305
under the air box
it is located under the airfilter. Remove the air box and the 2 screws holding the cables on the ECM. After the cables are disconnected you can just lift out the ECM.
Ecm = engine control module. 1998 and before it controls cruise, alternator and ac. On a 1998.5 and later it also controls the actual fueling and running of the engine.
might run lean? you could try it and check your plugs or if you hear pinging good sign running lean . if it is mass air set up should compensate for change if speed density will not and need to change ecm or get reflashed
The ECM on mine (2.5L of that year) is to the right side of the battery, up against the frame, integrated with the air intake.
You can't. It doesn't have a distributor. The ECM does all that stuff electronically.
