Corsa mass air flow meter symptoms kia sedona

Same me result, only different coloured earth, like i said i wouldn't touch any wiring unless i was 100 sure, i wasn't and neither where nobody on here could give me the answer to my the reason i took it too the garage was they. Mass Air Flow Sensor (Appearance will vary.) Step 2 - All maf sensors include an electrical connector which is used to transfer data to the computer. This is needed to keep the exhaust emissions low without sacrificing the engine performance. Lift the hood and disconnect the black, negative battery cable.

Mass flow sensor - Wikipedia, the free

The temperature sensor measures the temperature of the air near the hot wire. Step 1 - The mass air flow sensor is designed to monitor the volume of air passing into the engine at any giving time (located in the intake tube connected to the throttle body) this information is then transmitted to the computer for calculations while. A bad or contaminated mass air flow sensor cannot measure the amount of air flow correctly. A hot-wire mass air flow sensor has a small electrically heated wire (hot wire) and a small temperature sensor installed close to the hot wire. Have you ruled out the simple things like an air leak downstream of the MAF?

Do you actually know how to test a MAF I don. While your at it check the camshaft retaining bolts for tightness.

What are the symptons of a

Basic testing Check the condition of the vehicle wiring harness and if output voltage is correct. Read about testing and replacing the air flow sensor on the next page. The main type of MAF sensor is a hot wire or film type. As the wire heats up, the electrical resistance increases, so causing the current flowing to decrease.

How a hot-wire air flow sensor works. Btw tried a multi meter on the plug to the maf and get the following on each of the five pins. Tags: technical issues warning lights electrical faults engine problem Can anyone help! Edited by Andy Bairsto on at 15:55.
