Upgrade today to remove Google ads and support TLF.

22 is throttle position sensor, 34 is MAP sensor. The first could cause the second. Check voltage readings and connector security on TPS. A direct replacement is from a Vauxhall Corsa, very reasonable!

Spot on Sparky,

Had freescan runing on Wednesday night and engine fault light came on and TPS sensor voltage went to zero confirming fault code.

Took your advice and looked on ebay for Corsa TPS and got one for £12.00. (GM part number 17106688/17087653).

Parts came today fitted and cancelled codes and the engine runs spot on idel speed as it should be and no light on dash on test run.

Thanks

Andy.
