IPD plenum still puts CEL on HELP!

[Stunin_Stud]

Ok guys I finaly got the code. its P0102 mass air low input. This is a new MAF i put in could it be messed up or what. Thanks

one type of test is to unplug the wiring to the sensor and see if it idles better

The car Idles fine. it runs excellent. The CEL is on and when I reset it or disconnect the battery it comes on immediately when I drive it.

When I first installed the IPD plenum and cold air intake with a non oiled filter, the light came on and the car ran bad. I changed the MAF and now the car runs good but the CEL comes on with P0102-Below lower limit code.

Should I get a new MAF or is this problem something else like wiring?

what does the repair manual say for testing 0102 ?

[mikefocke]

– Open circuit
– Short circuit to ground
– Mass air flow sensor

I disconnected the plug to the MAF and turned the car on and the car ran fine. I plugged it in and it ran fine again. Basically no change with it plugged in or out.

what does open circuit or short circuit to ground mean? how do I know its grounded or open?

Could this be a problem with the Intake or filter?

thanks guys

maybe go to a shop that has the proper test equiptment. the code does seem to point to a bad MAF sensor buti would do more testing and that requires pro books,meters,scan tools etc
