2008 Chevy Kodiak c4500 duramax desiel code reader (Innova 3100 Can OBD2) shows P0102, what does it mean


P0102 Chevrolet - Mass or Volume Air Flow Circuit Low Input

Read more: http://engine-codes.com/p0102_chevrolet.html#ixzz38p5k1ZD8

Possible causes - Faulty mass air flow sensor
- Intake air leaks
- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor circuit poor electrical connection

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.

Error codes P0507 and P0102 after replacing MAF sensor


P0102: you need to make sure the sensor is clean; sometimes it get dirty as you are working on an old car. Check the voltage manually. Make sure there is no air leak near it

P0507: high idle... this sounds like a vacuum leak. get starter fluid and start the car. Spray around and check for change in car idle

1998 corolla dies when idling runs ok driving


Engine stalls cold or RPM fluctuates at idle up and down or dies near idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control. If the above cleaning doesn't cure your issues you need to have the computer controlled automatic idle speed control system diagnosed and repaired by a dealer or electronic engine control repair shop.

P0102 Code on 98 Chevy 2500 van


Check to see if the pink wire on the mass air flow connector has voltage with key on.It come's from fuse #15 inthe under hood power box.Also called eng 1 fuse.If voltage is present try the old trick of using carb cleaner to see if you have a vacuum leak.that will also cause a high idle oon fuel injected veh.If you can't find anything ther your going to need to see your mechanic to trace the trouble tree down for that code.There is a long process for that code. Good luck.

Fault codes, p0102,p0122,po507


po102--maf sensor, could be a bad air cleaner and not letting air into engine, po122--tps pedal position sensor low, replace or adjust tps sensor,or wiring,po507--idle control system high input. for this you can take off idle air control, and clean out carbon from were it mounts on engine. it is just before throttle body at end of air intake hose, it is black. do not push on pintle on end of valve when cleaning, use a old toothbrush to clean carbon off of valve, use carb cleaner but do not soak valve in liquid of any kind. good luck!!
