REMOVE SNORKEL AIR TUBES BETWEEN GRILL AND AIR CLEANER. REMOVE ENTIRE AIR CLEANER--(PULL UP FROM BOTTOM OF UNIT, IT IS JUST HELD ON WITH FOUR CLIPS) AT REAR OF ENGINE YOU WILL SEE A ROUND AIR INTAKE THE SENSOR IS IN THE TOP TUBE. USE FLAT BLADE SCREW DRIVER TO PUSH IN THE CLIP AT THE REAR AND REMOVE THE TUBE UNPLUG THE ELECTRICAL CONNECTION. THE SENSOR IS SCREWED IN WITH 2 TAMPER PROOF SCREWS REQUIRING A SPECIAL BIT (5 STAR WITH A HOLE IN THE CENTER) I GOT ONE FROM A TOOL TRUCK (SNAP ON ETC)

SOURCE: MASS AIR FLOW SENSOR REPLACEMENT & DIAGRAMS

Very easy for the Mass Air Flow Sensor....it is in the duct between the throttle body and the air filter box. Just unclamp the tube and remove the old and replace with the new.

If the mass flow sensor was bad, the check engine light should of came on giving off an engine code. To remove the mass flow, disconnect battery neg cable, then pull of the wire harness and pull out mass. You will probably have to remove the air intake hose.

Code 157


Error code 157 on your vehicle indicates a problem with your mass airflow sensor. The mass airflow sensor gives a reading based on the air intake and output within the engine compartment. A properly functioning sensor will contribute to better fuel economy. In some instances, you may be able to clean your mass airflow sensor to clear the error code, but the error will most likely return in a short time. Fortunately, replacing the mass airflow sensor is a reasonably simple repair.

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.

Fault Code Description

  • 36 - Mass Air Flow sensor error

    Symptoms

    • Engine stalling
    • Lack of power

    Common Problems Faulty Mass Air Flow sensor,Broken wire to Mass Air Flow sensor,Dirty sensing element in Mass Air Flow sensor

      P0100 OBD-II Trouble Code

      Technical Description

      Mass Air Flow (MAF) Circuit Malfunction

      Basically this means that there's a problem with the Mass Air Flow (MAF) sensor or circuit.

      You will likely not notice any serious driving problems, but there may be symptoms like a general decrease in power or sluggishness.
      Causes

      A code P0100 may mean one or more of the following:

      * The MAF may be disconnected, or a wiring connection may be bad.
      * The MAF sensor may be faulty.

      Possible Solutions

      Use an OBD II Reader (or go tou your local parts store and they will for free) and reset the code and see if it comes back.
      Then start with the cheapest, easiest repair procedures:

      * Check the Mass Air Flow Sensor wiring/harness is connected properly and that there are no broken / frayed wires.
      * Unplug and reconnect the MAF wiring harness a few times to clear the contacts.
      * Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information).
      * Replace the MAF sensor.
