SOURCE: 98 chevy suburban, code reads mass air flow sensor

Check the wire leads and clean them before reconnecting the wire leads. It wouldn't hurt also to clean the MAF sensor with MAF cleaner, the code your getting is most common to the high performance oil base filters like K&N.

Good luck and this should help you resolve your MAF issues. Thank you for using Fixya

SOURCE: 98 chevy blazer misfires when cold

Don't know if you got your answer. I found my Timing gear/chain set worn very badly. Cam bouncing. Causing the distributor to misfire between 2000 to 3000 rpm. You can check your play by pulling the distributor cap. Then bar the crank damper back and forth. The rotor button should rotate at exactly the same time the serpentine belt moves. Best way to do this, is to have somebody bar the engine while you put one hand on the rotor and your other hand on the A/C pulley. Rotor and pulley should start to move together. Check by rotating the other way.There will be play only if you reverse directions. If so, pull the timing chain cover and check the gears. Hope this helps.

SOURCE: Would a problem be caused to use a 2003 Suzuki Esteem Mass Air Flow Sensor on a 2002 since it seems to be working great

They have to be exactly the same part electrically,etc

No way to know that unless the part number & application is the same

Your cars pcm won't have proper air flow readings if you don't
have the correct sensor

Are they the same,Don't know,that is up to you to research

Where is the air charge temp control sensor located on a 1999 ford explorer 4.0 sohc

Generally the Air charge temp sensor is in the intake tube between the air box & the intake. However, there is a possibility that it is part of the Mass air flow sensor.

1997 chevy silverado starts one day next will not start

The next time it does not start have someone crank it over while you tap on the mass air flow sensor,if starts then remove the mass air flow sensor and clean the small wires inside of it using a non-chlronated brake cleaner let dry 10 minutes then re-install.

I got the code from the OBD IT read a code of 23 and one of 36 now i need to find what it means

code 23 is MAT too low.(mass air temp.) code 36 is Mass Air Flow Sensor Error

The ECM receives a signal from the Mass Air Flow sensor depending on the amount of air entering the engine. The ECM uses information from this sensor to help calculate fuel delivery and spark timing.

  • 36 - Mass Air Flow sensor error


    • Engine stalling
    • Lack of power

      99 Chevy Blazer(4.3) will not start on cold mornings(20-30 degrees). Will turn-over but not start. Once the Sun is up and it warms up, will start all day. Distributor changed about a year ago.

      Sounds like a coil intermittent. Try a new coil or if you want to test it you can connect an ohmeter to the wires then put it in an oven at about 200 deg. Watch for opening, increase in ohms, in the coil wires.
      Hope this helps.

      98 chevy lumina. Code 113, 102, 171. runs then

      the code 113 is intake air temp cicuit, high input.
      the code 102 is mass air flow volume air flow circuit, low input.
      the code 171 is system too lean (bank 1)
      I sure hope this helps you out. Dont sound like anything too major though

      98 Jimmy has 5 codes (multiple misfire; egr; mass air flow; intake air temp; manifold pressure) Was dogging out on me and the other day it quit. Now it turns over but will not start. Checked and it is...

      I would start with the Mass Airflow and EGR sensors first, because they can cause the misfire codes and the intake pressure and temp. Just because the air filter and hoses are clean and free flowing doesnt mean the computer can see that. If your Mass Airflow sensor died, as far as the computer is concerned, there is no air going into the engine.

      Need to find Mass Air Flow sensor on 98 Camry

      You are not stupd! :-) This car has a speed-density system. The computer is programmed to meter fuel and spark timing from manifold absolute pressure (MAP), engine temperature, air temperature, and throttle position only.
