wagon in the limp home mode?

[baudenfj]

My E320 95 is in limp home mode! I pulled the codes and get

Pin 8 - code 11 O2S1 heater...
and code 45 - Fuel safety shut-off to engine control module (HFM-SFI or left or right LH-SFI)

Pin 14
11 Closed throttle recognition signal to engine control module (HFM-SFI or Left LH-SFI)

The wiring harness has been replaced as well as the OVP relay.

Here is what I read in the manual...

If the throttle valve is opened further than specified by the accelerator pedal because of malfunction and the Tempomat cruise control is not in use, a safety contact in the actuator switches a ground signal to the LH control unit via the electronic accelerator pedal control unit. This interrupts fuel injection, which is restored again at a certain engine speed depending on the engine!

Does this mean my ETA is SHOT? I replace it 5 years ago with a new one!

Cheers,

Franz

Could be as the wiring in those if you got an off the shelf model the wires inside could be crumbling. Same reason you ask what year wiring harness was made as they had old insulation on them. Sorry to hear about you having issues.

I measured the potentiometers on the ETA!

Pin 1/2 - I get a varying resistor between 1190 - 1710 Pot 1?

Pine 2/3 - I get a constant resistor of 1380!

This must be it! I think we they recondition these ETAs most shops only change the wiring! We all know it goes bad. Some might rewind the actuator!

I am not sure what to do? The best thing would be to get one from a low millage car. Rewire it and be done with it. I fear if I get a remanufactured one I might have the same problem a year down the road.

Has anybody got one for sale?
