Okay, seeing some interesting variation in this thread. The FSM repeatedly says the normal operating range for the A343F is 158f-176f. But some seem to never get into this range, with typical readings between 120f-140f. I am seeing values in the FSM range during typical driving.
For earlier models, the PCV neck is so narrow, I’m not sure what you’d “stuff” down there that would keep debris from falling in while also giving yourself enough clearance to work on the hard rubber. Give it a shot and report back.
To circle back, my issue earlier was simple. I did not realize that the vehicle exits programming mode immediately if the key fob sequence is not exact. Quick simultaneous press. Then unlock. You get one shot or must restart.
Thanks @BnvS. Does the ECU limit the number of fobs or is it the master key? I always thought the constraint was 5 masters. Was able to program the key as a master, just not the lock/unlock function.
This worked like a charm. Manually cycling just the driver door works perfectly.
Steps: Driver door open, unlocked. All other doors closed. Key in ignition and back out (do not turn). Manually cycle driver door lock five times. Close door. Open door. Manually cycle driver door lock five times...
@bcomnes did the swap end up fixing the screeching sound? If so, still have the accumulator for sale? My dad’s GX screeched a couple times at start up this morning.
