Hi, my car was shutting off at random, at the most uncomfortable times ofcourse... No hesitation, nothing just shuts off while driving or standing at a stop light, and would not start after that.

Got engine faults, is says P0332 - engine speed sensor - no signal.
checked the manual, engine speed sensor aka frankshaft position sensor with grey plug and 3 contacts under the coolant expantion tank. Got it tested with multimeter, contacts 1 and 2 have 900ohms (if I'm reading myltimeter the proper way ) everything esle is no contact.
Ordered new sensor, got it today, it shows exactly the same 900ohms, what;s wrong? The test does not mean anything and old sensor might be still bad, or something else going on>?
Can I have a broken wire from sensor to ECU? Does anyone know to what pins in the ecu the sensor is connected so I can check the line?

car is 2.8 aha, automatic transmission.
Thank you.

 

From the Bentley for AHA engine:






Knock Sensor2 Circ.
Low Input

Sounds like you may be chasing the wrong sensor.

Can you get a Vag Com scan?

 

Sorry, my bet, it's P0322 =)
The scaner called it to be Engine speed sensor. I checked my dumb audi manual and the thing I bought is called the 'engine speed sensor' in there.

Can you please check your manual for the correct code?
Thanks.

 

For P0322, the Bentley says:

[align=center]Immed.[/align][align=center][/align][align=center][/align][align=left]Here's the process for checking the wiring between the ecm and the sensor:[/align][align=left][/align][align=left]



-
Check wiring for open circuit between ECM/test box and 3-pin harness connector.





Connector terminal 1 to ECM/test box socket 67





Connector terminal 2 to ECM/test box socket 63





Connector terminal 3 to ECM/test box socket 56





Specified value: max. 1.5



-
Check wiring for short circuit between ECM/test box and 3-pin harness connector, according to wiring diagram.





Connector terminal 2 to ECM/test box socket 67





Connector terminal 1 to ECM/test box socket 63





Connector terminal 1 to ECM/test box socket 56





Specified value:
If wiring is OK:



-
Replace engine speed (RPM) sensor -G28-.



-
Check readiness code Page 01-80 . If Diagnostic Trouble Code (DTC) memory has been erased, or ECM was disconnected, generate new readiness code Page 01-83 . [/align]

 

Hopefully I understood the test completely:

term 1 to socket 67:
term 2 to socket 63:
term 3 to socket 56:
100% connection, 0 resistance.

term 2 to socket 67:
term 1 to socket 63:
term 1 to socket 56:
No connection

Is that what it suposed to be? Then I have bad sensor right?
I guess sensors own resistance does not really mean anything in this case.

 

That's the way I read it. Didn't see any reference to a check of the sensor itself.

Good luck!!

 

Well, I'll replace it and go for a ride, it should be abvious wery soon if it helped or not [8D]
Thanks.

 

hey, so did you have any avail with the crankshaft position sensor? i have the EXACT same problem and have been trying to fix it for weeks but can't seem to get it. hopefully there will be some response as i am STUMPED! I had the local indi shop replace the crankshaft sensor and it didnt do anything....
