If battery voltage is not present, check for open or shortĬircuit on White/Red wire between MAF sensor and main relay. Measure voltage between ground and harness connector If problem is found, repair as necessary and Light Green/Black wire between PCM connector No. If no problemĢ) Using scan tool, access PID/DATA MONITOR. Problem is found, repair as necessary and go to step 4). Inspect all applicable harness connectors. * Open or short circuit between Powertrain Control Moduleġ) Ensure FREEZE FRAME PID data has been recorded. * Open or short circuit between main relay and MAF sensor. Ĩ6 volt with engine started for 3 seconds. The sensor itself isn't a repairable item from what I can see in the shop manaual.ĭTC P0102: MASS AIRFLOW (MAF) SENSOR CIRCUIT LOW INPUTĭTC is set when input voltage from MAF sensor is less than. If you wanted to bet that it was the sensor you might be able to get the part for less from Trussville and just pop it in yourself. It sounds to me like you got charged too much for what you've got to date. $330 is probably on "book rate" for parts and labour to replace the sensor (it's an expensive bugger). $220 to pull the code and plug in the diagnostic tool sounds high. Not much you can do in the home garage on this one. Open circuit in wiring from PCM terminal 3C to mass air flow sensor terminal A.Open or short circuit in wiring from PCM terminal 2L to mass air flow sensor terminal B.Open or short circuit in wiring from main relay terminal D to mass air flow sensor terminal C.If all the wiring checks out, it's the sensor itself (could be the hot wire is broken or damaged) and it gets replaced. P0102 in the shop manual has you check the wiring, voltage and continuity as the diagnostics leading to repair.
