Does anyone have a procedure for bench testing a Bosch MAF sensor ?
I removed my OEM sensor 2 years ago after a problem with starting the car. The non OEM sensor corrected the starting problem and I stored the original sensor for future consideration. With the cost of the OEM sensors skyrocketing I would like to revisit the original sensor and see if it can be tested and or fixed.
The easiest/best way to test it is to try it on the car. Always a good idea to replace the 2 (power & burn off for '86 and up) MAF relays when installing a new MAF sensor. If a sensor circuit is not working properly it should deliver a trouble code to the ECM.
