Hi all,

Looking for confirmation of fault code definition for code 53 on the above vehicle. I get no coms using autodiagnos , Carmanscan gives code 53 but no definition.
Autodata lists as Oxygen sensor heater OR Exhaust gas control valve (curiously clicking on the Exhaust gas test on Autodata takes you to test for Cam sensor!)
CAPS & Tolerance do not list code 53 at all, an internet trawl lists as ISCV fault.

Confirmation of correct definition would be greatly appreciated

Thanks

Andy
