Maf Sensor Reading Too High
Maf Sensor Reading Too High - The maf sensor high voltage output to the ecu may have several causes: I had a friend get some readings from an obd2 scanner, which indicated that both precat o2 sensors (passenger side and driver side) had negative values. Either the maf sensor itself is faiing, or the circuit for maf has problems. You will find a list of possible reasons why the engine check lamp is lit here. And this damn code just started popping up at the same time that she's been running wierd on cold starts. There could be a broken wire in the sensor's circuitry.
Web the p0103 code signals a high voltage issue from the mass air flow (maf) sensor, which can stem from several underlying causes: Web the p0103 code stands for “mass or volume air flow (maf) ‘a’ circuit high,” which means the powertrain control module (pcm) detected a high voltage output coming from the maf sensor. I have a vagcom usb cable and i am trying to diagnose the maf sensor. Too little exhaust causes more air to be ingested by the engine due to lack of exhaust gas dilution, and the maf sensor is measuring this increased air flow. You may also notice changes in fuel consumption, or black smoke from the exhaust.

You will find a list of possible reasons why the engine check lamp is lit here. In addition, the map signal is used to control smoke by limiting fuel quantity during acceleration until a specified boost pressure is obtained, and is used by the pcm for egr system calculations and control. Often mass air flow sensor readings are measured at.
