Even if you have the most powerful automobile like the Chevrolet Silverado, and even if it is equipped with the most reliable original features and parts, it still needs routine checks and maintenance all throughout. A well-maintained application can mean notable fuel economy and safer drives - on-road and off-road. If you hate getting stranded on the road, especially if you are in a great hurry, be sure that you do your best to keep your car in its best shape. Say for instance, the Chevrolet fuel filter. This is a very crucial component of every vehicle as it traps out harmful elements that might mix up with the fuel. Particles cannot be just allowed to combine with the fuel as it will negatively affect the fluid�s function for the road performance of your Chevrolet Silverado. And, you cannot just leave it like that. Obviously, you must do something about it. That is through the highly efficient Hastings fuel filter. Yes, you got it right! Hastings is the brand that definitely has it.you need an immediate replacement for your Chevrolet Silverado fuel filter

MAKE SURE THE O RINGS ARE ON THE PCV, AN EASY CHECK IS TO PLACE YOUR HAND OVER THE OIL FILL WITH THE ENGINE RUNNING, IF IT TRIES TO **** YOUR HAND INTO THE VALVE COVER THERE'S LIKELY AN O RING MISSING FROM THE PCV.

It is a low voltage circuit supplied by the ECM. You probably need a new sensor.

I am getting three different codes on my 2001 Mercedes ml320. p0103, p0106, and p0453.


code p 0103 refers to mass air flow(MAF) sensor/ volume air flow(VAF) sensor --high input===causes ---short to positive---maf/vaf sensor/s---ECM
code p 0106 refers to manifold absolute pressure(MAP) sensor/barometric pressure(BARO) sensor---range /performance problem===causes ---intake /exhaust leak--map sensor---baro sensor
a leak here could be the hose to the cabin to control the vent operation, transmission actuator hose leak and the exhaust leak could be a cracked flex section of the exhaust pipe near the manifold
code p 0453 refers to evaporative emission(EVAP) pressure pressure sensor---high output===causes --wiring short to positive --EVAP pressure sensor---ECM
I would fix the EVAP symptoms first as as it will show as some of the problems you have mentioned

I HAVE HYUNDAI CAR 2002 SHOW HTIS CODE P0106 AND P0172. WHAT IS THE DEFFRENCE BETEEW MAP/BARO, VAF/MAF.


MAP = mass air pressure, Baro is atmospheric air pressure ( as in barometer), VAF = volume air flow and MAF = mass air flow . The baro sensor alters the air fuel mixture for varying altitudes that the vehicle can travel through. IE from flat plains at sea level to over the rockis.. The VAF sensor measures the volume of air passing through the air intake . The MAF measures the combination of volume and the density of the air flowing through the air intake to adjust the air fuel mixture as cold air is more dense and requires more fuel to burn completely. The MAP measures the vacuum in the manifold after the throttle control to adjust the air fuel mixture in over run situations so that the car will not backfire. All these sensors continually supply input to the ECM which continually compares them with the O sensors and adjusts the injector pulse to ensure complete burn of the mixture in all situations and engine rpm's.

code p0102 refers to MAF/VAF sensor ---low input ===causes --wiring short to ground. MAF/VAF sensor
code po172 refers to system too rich --bank 1=== causes ---intake blocked --EVAP canister purge valve---fuel pressure ---HO2S sensor
code po random misfires ---plugs --wiring ---injectors--low compression
code po305 refers to cylinder 5 misfire detected ===causes --engine mechanical fault--ignition/ fuel system ---injector ---ECT/MAF

I would check that the air filter is not blocked first as it affects the MAF/VAF sensors . Have a fuel pressure system pressure test done

99 Audi A4 quarto, keep having to replace same coil pack and code p0102 but changed the MAF. My last guess is the wiring has gone bad, but I don't know how to fix it or even where to start.


code p0102 refers to mass air flow (MAF) sensor/volume (VAF) sensor-low input===causes --wiring short to ground---MAF/VAF sensor--- ECM Replace the sensors and check for a wire shorting across to the earth pin. Code po102 has no reference to coil packs but check that the wiring to the coil has not been damaged when removing for replacement.

I have 2 pending codes for a 99' pontiac grand prix gt. p0107 map/baro ckt low input.. & p0113 iat sensor 1 ckt high. i need to figure out what these 2 problems come from & what problems will they...


Try unplugging and plugging the map sensor, this device should have manifold pressure hooked up to it, via hose, so check for cracks or leaks. Then clear codes and test again.
