Hi, I don’t understand the error code 00515 engine codes normally start with a ‘P’.

However ‘SHORT TO GROUND’ sounds like the wiring loom has chaffed on the engine or bodywork

[AskTheMechanicCoUk]

Most Vauxhalls flash the engine management light if the immobilizer is the fault.

I think you have Bosch Motronic M2.5 fitted, which uses an inductive crank sensor and not hall effect so wont have any power as it produces it own, see my video on Testing Crankshaft Position Sensor (inductive). I would volt drop all the earths and lives to the ECU, if ok I would look at the camshaft sensor, I think it is in the distributor and would be hall effect, but I think they changed pin numbers around 1991 so you would need the correct wiring diagram to test.

[AskTheMechanicCoUk]

Sensors and wiring can be affected by temperature change and vibrations. DTC are very useful with intermittent problems.

[AskTheMechanicCoUk]

Yes thats right, it is switching on and off, the meter just shows the average voltage

[AskTheMechanicCoUk]

The early type of Hall switches fitted to distributors had a 12v supply voltage, but as with most modern electronics (USB on PC etc.) they all work on a 5v supply voltage, this is the case for most vehicle sensors fitted now, from a air flow to throttle position. The early Hall type switch just operated a simple amplifier where a modern one sends information to the ECU/ECM to be processed. The 5v supply voltage will come from the ECU/ECM.

I did not know the GIECO Lizard fixed cars ...

I have a question, I have two camshaft sensor plugs on a Acura K20A2 engine and the first plug's power wire is at 10.00 DCV and the othe plugs wire is at 1.00 to 3.00 DCV and the first plug's switch wire is at .100 -.200 ACV when engine is cranking while the other one is pretty much at almost nothing. So is the low voltage camshaft sensor wire bad? Plus how do I fix this problem or what is going on. Please Help.

free wires? sick

Nice Videos, cheers!

on my audi a3 1.8se 2000 model computer has thrown error code 00515 camshaft position sensor hall effect SHORT TO GROUND.i had the camshaft sensor replaced along side the crankshaft sensor.symptoms are limp mode,heavy fuel consumption,cutting out.please advice how to fix this short to ground error,as the car been in the garage for 2 weeks and still not fixed!!! please help

Hi. I have a j reg vauxhall astra 2.0 16v engine. There is no power going to the crankshaft sensor at all and no signal going to the coil amplifier. I have carried out continuety checks, replaced ecu and crank sensor. Do you have any ideas what could be wrong? I think possibly immobilizer?
