My crank sensor for 1997 Audi A6 quattro is showing low voltage and wont start what is causing this

Throwing any codes? Crank sensor working? The cam and crank sensors typically work together to adjust timing.

Hi David, Remove the sensor and hook up an analogue voltmeter to the two cables. Set the meter at mili voltage and pass a metal screw driver across the business end of the sensor, without coming into contact with it. You should have a distance of about 0.5 of a millimeter gap between the sensor and the screw driver. The voltage generated is very small and the pulse will only occur as the field is broken. In other words its a two man job. If the needle of the meter moves the sensor is fine, if not replace it. It is very important to use an analogue meter as the pulse is too small to be noticed on most digital meters. Regards John

mine 97 audi a6 did the same thing, jack up the front passenger side, remove the wheel, and hit the starter a few times with a bar, and she will crank! promising results!

Note:
Only a high pressure service valve is used for A/C system servicing. A low pressure service valve is not installed. Perform all A/C system service (ie. discharging, evacuating and charging) through the high pressure service valve only.

resistance in the connectors between sensor or igniton module corosion ,loose connector or wire ,posibly the sesor or ign module itself requires further testing

Under bonnet on the right side of the car face to windscreen you will find the fuse box / relay plate - engine bay. Here is placed the Data Link Connector (DLC) for Audi A6 Quattro 1997.

I have a 1995 AUDI A6 QUATTRO, and it had similar problems which the AUDI repair shop had to fix.

i think you have a faulty starter. If you know where the starter is. you could get someone to knock on it. when you trying to start. Works sometimes. It also could be bad connection to the fuel pump. check/listen if it get fuel. when cranking.

i have a 1997 audi a4 2.8.i just finish replacing the timing belt and spark plug. when i try to crank it the engine does turn over like it wants to crank and it is getting fuel but i am not getting no spark

dealer only ,factory immobiliser is cutting in, try the spare key and if it doesnt start call the breakdown truck to take it to dealer
