Hi all,

I have this car with wiring faults. The engine loom for the injectors was bad with the CTS wires shorted. I replaced this loom and repaired the wiring for both AFM's, which was as bad.

It now only runs on the right bank, but will run on 12 sometimes with both AFM's disconnected. I have only 8v supply to each MAF which I assume should be 12v. These are 5 wire sensors which I assume should be - supply, earth, signal, sensor earth and burn off?

Can anyone tell me where the supply comes from? I have followed the wiring back to the module box. If I have to I will strip the box out but this does not look too easy. Also I cannot comm with the base module but I have 10.2v on the K line at the plug. I have tried AST, Snap-On and a Star Tester. This makes me think the fault may be in the base module or the module box.

Any input welcome,

Thanks in advance,
