Title: Fault code
Post by: omega V6 on 09 October 2010, 17:01:04
Hello, just did the paperclip test with the engine off and I got a 19 Incorrect RPM Signal, but I thought if the engine was off youre supposed to get a 31?  :-?
I did the test again with the engine on and got the 19 again. I did the test because there are a few different little problems with the car, but as I said I only got the one fault code. How can I fix this? Thanks for any help

That is a crank sensor faulty code, so replace and all will be well.

I would go for a genuine Vauxhall one.

Ahh ok but on the fault code list given by Marks DTM Calib it says:
17 Knock Signal Circuit 2
18 Knock Control Module; Replace Electronic Control Unit (ECU)
19 Incorrect RPM Signal
21 Throttle Position Sensor (TPS) Voltage High
22 Throttle Position Sensor (TPS) Voltage Low
Surely if it it were crank problems, the engine would be lumpy and noisy. Or are you just saying its the sensor that needs replacing, because its the quietest running omega ive ever heard and it drives lovely  :D

It generates a signal that the ECU needs to determine the position of the crankshaft and the number-one cylinder. This information is necessary to control ignition timing and the operation of the fuel injectors. The signal from the crank sensor also tells the ECU how fast the engine is running (engine rpm) so ignition timing can be advanced or retarded as needed. On some engines, a separate camshaft position sensor is also used to help the ECU determine the correct firing order. The engine will not run without this sensor’s input.

So just get a new crank sensor and it should be ok?
