Thanks for trusting us with your problem. I have trained in the automotive field and currently work as a shop foreman. I will be helping you today.
Verify the solenoid is 12 to 25 ohms. Check the Yellow wire from the solenoid back to terminal D1 of the Engine Control Module. If the wire harness and connections are good, unplug the ECM and power the solenoid through an amp meter and look for 1.2 to 0.4 amps of correct flow when the solenoid activates. Compare that circuit to terminal D7, the shift solenoid "A", they should both have the same current flow. If the circuit tests good and there is not a harness or a connection problem then look for the possibility of a faulty ECM even know it is new.
I have a feeling the problem will indeed be related to the lockup solenoid. Possibly a bad wire that is why you have to ohm it.
This is the standard code information.
The diagnostics shop that I deal with ran test for many hours yesterday and then claim that the wiring tests out ok. That is why I replaced the PCM later today...dame problem. Prior to all that I put a new lockup solenoid on. But now is is showing a different code than before P1753. I wonder why a new code, and doesn't this code point to the shift solenoid?
On this accord SE, I'm not sure there is a separate TCM is there?
But the reason it is switching codes would be related to a bad connection or voltage issue.
ok. Since I already switched the PCM, I will take it to a different diagnostics place just in case. This is my first time on the sight. After I close this window, can I access this thread again and continue to ask questions on this same issue?
You can always continue to reply to me. If you rate my answer this is how I get credit. But this does not close out the session. You can set a bookmark to the page and return even if you rate the answer now.
So to repeat, since I already replaced the PCM more than likly its a wiring problem? Do you think its prudent to simply replace the shift solenoid? or not?
Did you already replace the shift solenoid once before?
No, I replaced the lockup solenoid
That is what the first code was saying
I would not throw anymore parts at it.
Just ohm the sensor this is simple and easy to do.
If it is out of spec replace.
ok. I will run with the wiring at the diagnostics shop and start there.
Excellent. Keep me posted. If I can do anything to help just give me a message.
I will rate and then come back after I run into the next wall
I will talk to you soon!
