Hi, I have a code p1450. I grounded the control wire from the air pump relay and the air pump turned on and at the same time 2 vacuum air solenoids next to the ignition coil did not come on. What could this problem be? How do I test the wiring coming to these solenoids, are these solenoids using the same control source wire? I don't have a scanner to check these wires.
I also checked the air pump control relay wire coming from ECM to the relay and there is continuity.
I checked the solenoids hanging near the ignition coil with 12 volts and it clicks and I can blow air through it once I applied power and can't when voltage removed.
I like to know what to check first before replacing the ECM. If I replace the ECM, what equipment do I need to make the unit work and will the old key still start the engine if ECM replaced?
have the same problem?
