idle issue

MA70-3.0GT · 11-09-2009, 05:08 PM

Meant to say, the diag test showed code 51 (switch signal) & lists the TPS not having an IDL signal as a possible cause, or the "A/C switch. A/C circuit & A/C amplifier". What's A/C stand for in this case, not aircon obv.?...

Anyway, first chance I get I'm going to calibrate the TPS, although I can't do the timing till I can get the swine started again (Might just be out of petrol now though). Just need to find out about the A/C thing too.

EDIT-: OK so it was aircon, just never clicked that it'd be integrated into the idle circuit. Now I think of it, it has to be to bump the idleup when the compressor kicks in! Anyhow I guess the 51 is just telling me to do the TPS so I'll go do that tomorrow.
