The engine control module (ECM) monitors the high side refrigerant pressure through the A/C refrigerant pressure sensor. The ECM supplies a 5V reference and a low reference to the sensor. Changes in the A/C refrigerant pressure cause the sensor signal to the ECM to vary. When the pressure is high, the signal voltage is high. When the pressure is low, the signal voltage is low. When pressure is high, the …

09/07/2021· Often mass air flow sensor readings are measured at idle, 1,000 RPM, 2,000 RPM and 3,000 RPM. A contaminated or bad air flow sensor will, in most cases, show lower air flow readings than a known good one. In some rare cases a bad sensor may show higher readings. Of course, different engines will have different readings. The air flow depends on the engine …

That’s another clue that the mass air flow sensor has failed inspec, meaning it’s not functioning correctly but the malfunction is not bad enough to set a fault code. Testing. A faulty MAF will have the same effect on both banks of a twobank engine. If a fault code or some other symptom shows up only on one bank, the MAF is probably OK. A dirty MAF can be diagnosed quickly and accurately with a scan …
