Corsa-B.uk - Vauxhall, Opel and Holden Corsa B Owners Club

Thought the car wasnt spot on. did a diagnostic test today in my dinner hour lol. I know I need ro disconnect battery and reconnect as i havent done it since ive owned the car.

Have the following errors showing at the moment tho:

13 - oxygen sensor - no change in voltage/open circuit = I have just replaced this so should dissappear once disconnecting battery

19 - Crank Angle sensor - incorrect RPM signal - got s spare, should i swap it or just clean it up?

22 - Throttle potentiometer sensor (TPS) - Low voltage= whats this and where?

35 - Idle stepper motor - poor or no idle speed control = I have one of these to put on. (Idle speed control valve yeh?)

67 - Air flow sensor, hot wire meter - signal is outside normal operation parameters (out of range)

68 - Airflow sensor, hot wire meter - Faulty air mass meter signal, incorrect frequency. - does this mean its fooked?

Any help would be much appreciated. Car drives ok but idles a bit high sometimes and can be a tad jerky from cold.

Just swap you idle control valve. This should sort it.
Then re-set the ECU.

how much was it for a diagnostic test as my corsa keeps poping up the ecu light but runs the same

What Do u mean by the paperclip test sorry im new to this and how long do u disconnected the battery for... thanks
