E4OD - Errorcode 1, 23 and 29
Hi, my -92 E350 7.3 E4OD have a flashing od-ligt and I'm getting errorcode 1, 23 and 29. Check engine lamp flashes in this order: 1 (weak/very short), 23, 23, 1, 29 29.
What does these codes mean?
The trans misses gears, hard shifts, can't decide which gear to chose, "hard" downshift while stopping. TPS/FIPL reads 0.98V and goes smothy up to 3.8V and TPS/FIPL are the "bad black one".
Anyone who can list/link to all the different errorcodes which the trans can set? I cant find a list anywhere...
Thanks!

"1" is not a fault code, it is a separator between the EO/ER and the continuous memory codes.
23 = a problem with the TPS or the throttle mechanicals
29 = PSOM output signal problem
Does your RABS work correctly? The PSOM uses the rear differential RABS sensor as its input. A bad sensor will screw up the whole shifting strategy and the PCM won't know when to shift properly.
Sounds like other vehicles that have a bad VSS sensor...

Where did you find these codes?

I have just tried another instrument and the transmission shifts like it should.
Then I guess it was the PSOM which was faulty. I forgot to test if the cruisecontrol started working again.
