Check engine light on with codes for mass air flow, air intake temp sensor, and trans. range sensor. We've had a hose replaced, I think, connected with air intake (not sure) 6 mos. ago. What does all this mean? The serviceman replaced a spark plug and reset check engine light to get us on the road. He said it could go out again anytime or even later like next year.... What should we do? A dealership serivce technician is going to charge us a lot, I'm sure. Should we just trade it now, while it's running? or is is worth trying to get it repaired? It has 92,000 miles.
There could be only one sensor causing all these problems.Usually when one sensor goes bad the other ones will get a bad reading and they will read a fault code.Looks like not to many miles on it.Its worth the fix because those cars run forever.Hope this Helps you and Have a great day

P0103 - Mass or Volume Air Flow Circuit High Input
Possible causes- Dirty mass air flow sensor - Dirty mass air filter - Mass air flow sensor harness is open or shorted - Mass air flow sensor electrical circuit poor connection - Intake air leaks - Faulty mass air flow sensor
P0101 ISUZU - Mass Air Flow Circuit Performancehttp://engine-codes.com/p0101_isuzu.htmlForum CodePossible causes- Dirty mass air flow sensor - Dirty mass air filter - Mass air flow sensor harness is open or shorted - Mass air flow sensor electrical circuit poor connection - Intake air leaks - Faulty mass air flow sensor Tech notes Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor
P0103 MAZDA - Mass Air Flow Sensor High Input Signal
Possible causes
- Dirty mass air flow sensor - Dirty mass air filter - Mass air flow sensor harness is open or shorted - Mass air flow sensor electrical circuit poor connection - Intake air leaks - Faulty mass air flow sensor
P0113 is air temp circuit high. The maf sensor (mass air flow) sensor just measures the amount of air entering the engine. The iat (intake air temp) sensor is the one that detects the temperature of the air.
Change that sensor, and the code should disappear. It is located in the intake manifold or air plenum.
Your map sensor, otherwise known as mass air flow sensor is probably bad. You should replace it. it is normally located between the air filter and the throttle body. It senses how much air is going into the throttle body so the car knows how much fuel to inject.
