MG ZR: Cams & Maps

[lolsteve]

Cutting it fine but lambda is all wired up now *yay*
Guy who did it though cleared the warnings and told me there's two non o2 sensor codes *boo*

Codes P1520 & P1522. Apparently P1520 is an earth fault that loads of them have and can be ignored since it's something to do with the mgf having an oil temp sensor but the zr doesn't
P1522 is tricky though since apparently it's down to the same thing according to MGRover

"During various diagnostic routines, the fault flag P1520 and P1522 may appear.

P1520 - Oil gallery Temp fault
P1522 - Unknown fault code.

This condition is due to the same T4 software being used for the MGF VVC models.
Unlike the MGF VVC the MGZR 160 and Rover GTi does not have an oil temp sensor fitted. The software looks for the presence of this sensor and produces a fault code when it can not locate it.

Please advise all technicians using testbook/T4 to ignore this message if it appears"

But others on forums are saying it's the vvc solenoid and could still be a problem..
Bloody rovers
