![]() O.k here are the conditions and numbers. First I ran the car for 3-4 minutes then shut it off, I un-plugged the MAF sensor, then plugged the VOM up and with the key in the on position I probed the VPWR(power from computer) and the PWR GND (power ground)with the meter set on DC-V #20 I got 12.15
Next I tested the OHMS with key in the off position,still with the MAF sensor un-plugged and with the VOM set at 2000K and probing the MAF SIG, and the MAF RTN, I got 130. Then I turned the meter to 200K and got 131.3. Also with the VOM set on ohms, I probed the MAF SIG, and the PWR GND with the key in the off position and at 2000K I got 101 and with the meter set on 200K got 101.7. Last test I did was Volts, I started the car up and with the MAF plugged up I probed the MAF SIG and the PWR GND, with the car idling and the VOM set on DC-V #20 I got +0.02, I think this is to low and if it is what do I do. ![]() * I also tried idling the car up while testing and no affect on the reading. |
