We currently have a 95 Diamante in the workshop at the moment. has an intermittant cut out problem - seems mostly on corners at slow speed. direct cut - like fuel or ignition. the fault codes appear when bridging pin #1 (fault code mode trigger) and #4 (earth) - ECU lamp shows fault code - 32 - TCL lamp shows fault code - 75. 32 = MAP sensor. 75 I have no idea, havent been able find information on this anywhere. Is anyone able to help with this - is it a common problem, what does fault code 75 mean?!?
I have checked all voltages, powersupplies and earths on the map sensor. it appears to work fine. 1.3V at idle within spec. but I dont have an ECU pin diagram so I cant work out which pin it is to see if the working Map sensor is getting its signal to the ECU itself. Anyw help would be much appreciated, thanks
