Hey guys, jsut did a fault code check and it came back with: 23 - Intake Air Temp sensor(voltage High) 32 - Air Flow Sensor(Voltage out of range) What and how do i fix these? ive got the gregorys manual and for fault code 23 it says to check the voltage between the harness connector terminals and it should approx be 5 volts. i couldnt get any volts out of it(i think my multimeter may b screwed) and for 32 it says to check the terminals A and C on the harness, i didnt get anything out of terminal A or C, but with a test light i got it to light up using terminal C?? (may need to buy myself a new multimeter) Is any of these two codes of any concern and will they do any damage if left? could they be affecting the permformance/fuel economy/temperature of my car? Any help would be appreciated Nick ok, i just cleared the codes(disconnected the battery) and went for a 5 min drive round the block. came back and did the fault code check again and it still came back with codes 23 and 32, but now its saying theres a fault code 25, which is: Intake Air Temp sensor(voltage low) so now its telling me that the voltage for the intake air temp sensor is to high and to low?? I think im gunna have to go buy a new multimeter tomorrow.... anyone else got any ideas/suggestions on how to fix this? Nick

possible faulty maf

Codes in the vs are electronically erased, you either need the tech 1 tool or there is two terminals you can bridge with the right amount resistor to clear them. Are you testing these at the sensors also? sounds like a possible charging fault.
