What is a solution to fixing the mass air flow system, with code po121


DTC P0121: Throttle Position (TP) Sensor 1 Performance
Circuit/System Description
The engine control module (ECM) uses the following information to calculate an expected airflow rate:
?€¢
The throttle position (TP)


?€¢
The barometric pressure (BARO)


?€¢
The manifold absolute pressure (MAP)


?€¢
The intake air temperature (IAT)


?€¢
The engine RPM


P0121 The predicted air flow and the predicted MAP combined are outside a calibrated range for more than 3 seconds.
Circuit/System Testing

  1. Inspect for the following conditions:
  2. ?€¢
    Vacuum hoses for splits, kinks, and proper connections as shown on Vehicle Emission Control Information label


    ?€¢
    Inspect thoroughly for any type of leak or restriction


    ?€¢
    Air leaks at throttle body mounting area and intake manifold sealing surfaces


    ?€¢
    Throttle body for dirt, debris, and coking--Refer to Throttle Body Cleaning.

  3. Allow the engine to reach operating temperature. Observe the MAP Sensor Voltage parameter with a scan tool. Voltage should be more than 0.8 volt and less than 4 volts.
  4. ?‡'
    If more than 4 volts or less than 0.8 volt, refer to DTC P0106.

  5. Idle the engine. Observe the MAP Sensor kPa parameter with a scan tool. Increase the engine speed slowly and then back to idle. The MAP sensor kPa should change smoothly and gradually as engine speed is increased and returned to idle.
  6. ?‡'
    If the MAP sensor kPa does not change, refer to DTC P0106.

  7. Take a snapshot of the engine data list while performing the actions listed below. The mass air flow (MAF) sensor g/s should change smoothly and gradually as the engine speed is increased and is returned to idle.
  8. ?€¢
    Idle the engine.


    ?€¢
    Increase the engine speed slowly to 3,000 RPM, then back to idle.


    ?€¢
    Exit from the snapshot and review the data.


    ?€¢
    Observe the Mass Air Flow (MAF) Sensor parameter frame by frame with a scan tool. The MAF sensor g/s should change smoothly and gradually as the engine speed is increased and is returned to idle.


    ?‡'
    If the MAF sensor g/s does not change smoothly and gradually as the engine speed is increased and is returned to idle, refer to DTC P0101 or P1101.

  9. Inspect the throttle body for the following conditions:
?€¢
Loose or damaged throttle blade


?€¢
Broken throttle shaft


?€¢
Any throttle body damage


?‡'
If any of these conditions exist, replace the throttle body assembly.

V70 rpm high fluctuation at idle and engine stops


I would start by unplugging the throttle position sensor then start it and see if there is a change. Could also be the slow idle sensor or the crank position sensor? Have you looked that code up or had it computer checked? most the auto part stores here will let you use one in the parking lot hope that helps

Have 03 Chrysler Sebring 2.4 Lx with a very high idle. (Undriveable ) replaced the map and throttle position sensor. That didn't work. Any ideas?


your throttle body door is stuck open check the cable from the gas pedel to the throttle body. if anything just to both cables off the throttle body andrun it. if it is the same with cables off when your idle air control valve is bad

it is possibly the throttle position sensor(tps) malfunctioning. basically the computer or "brain" of the car thinks the throttle is in a different position than it really is and automatically makes adjustments to fuel, air ect.... based on these false readings from the sensor thus causing the engine to react a little different when you expect to have power.

2004 Sebring with 2.7 engine. MAF needs cleaned and hpoefully not replaced. Need help locating and the procedure for removing, cleaning, and replacing. Thanks, Keith


I wouldn't remove the sensor. Get yourself a can of electrical parts cleaner. They have it at most car parts chains. Then, just take off the air filter and look inside the inlet. The sensor should be right there. Don't touch it. Just give it a couple of good sprays. More if it looks dirty. I have pasted info below on you system that I copied from autozone.com. Let us know if you have more questions, and thanks for using FixYa!


Operation The Mass Air Flow (MAF) sensor is an air flow meter that measures the amount of air entering the engine. The Electronic Control Module (ECM) uses the MAF sensor signal to provide the correct fuel delivery for all engine speeds and loads. A small quantity of air entering the engine indicates a deceleration or idle condition. A large quantity of air entering the engine indicates an acceleration or high load condition. The MAF sensor has the following circuits:



An ignition 1 voltage circuit A ground circuit A MAF sensor signal circuit An IAT sensor signal circuit A low reference circuit

The ECM applies 5 volts to the MAF sensor on the MAF sensor signal circuit. The sensor uses the voltage to produce a frequency based on the inlet air flow through the sensor bore. The frequency varies in a range of near 1,700 Hertz at idle to near 9,500 Hertz at maximum engine load.


Removal & Installation


  1. Before servicing the vehicle, refer to the Precautions Section.
  2. Disconnect the negative battery cable.
  3. Remove the air pump assembly.
  4. Remove the 2 bracket mounting bolts.
  5. Remove the bracket assembly.
  6. Disconnect the electrical connector to the Mass Air Flow (MAF) sensor.
  7. Twist the MAF sensor sideways and remove it from the bracket.
  8. Remove the rubber mounting.

    Fig. Remove the 2 bracket mounting bolts


To install:
  1. Install the rubber mounting to the MAF sensor.
  2. Twist the MAF sensor sideways and install it into the bracket.
  3. Connect the electrical connector to MAF sensor.
  4. Install the bracket assembly.
  5. Install the 2 bracket mounting bolts.
  6. Install the air pump assembly.
  7. Connect the negative battery cable.


Testing


  1. Verify the integrity of the air induction system by inspecting for the following conditions:

    Damaged components Loose or improper installation An air flow restriction Any vacuum leak Water intrusion
  2. With the engine running, observe the scan tool Mass Air Flow (MAF) sensor parameter. The reading should be between 1,700-3,200 Hz depending on the Engine Coolant Temperature (ECT).
  3. Verify that any electrical aftermarket devices are properly connected and grounded.
  4. Inspect the harness of the MAF sensor to verify that it is not routed too close to the following components:

    Any aftermarket accessories The secondary ignition wires or coils Any solenoids Any relays Any motors
  5. A low minimum air rate through the sensor bore at idle or during deceleration may cause a DTC to set. Inspect for the following conditions:

    Any deposits on the throttle plate or in the throttle bore Any vacuum leak downstream of the MAF sensor
  6. Inspect for any contamination or debris on the sensing elements of the MAF sensor.
  7. Inspect the air induction system for any water intrusion. Any water that reaches the MAF sensor will skew the sensor and may cause a DTC to set.
  8. A Wide Open Throttle (WOT) acceleration from a stop should cause the MAF sensor parameter on the scan tool to increase rapidly. This increase should be from 3-10 g/s at idle to 150 g/s or more at the time of the 1 to 2 shift of the transmission. If the increase is not observed, inspect for a restriction in the induction system or the exhaust system.
  9. Inspect for a skewed or stuck Engine Coolant Temperature (ECT) sensor.
  10. Test for a high resistance of 15 ohms or more on the ignition 1 voltage circuit. This may cause a DTC to set. A high resistance may also cause a drivability concern before a DTC sets.

The Barometric Pressure (BARO) sensor that is used in order to calculate the predicted mass air flow value is initially based on the Manifold Absolute Pressure (MAP) sensor at key ON. When the engine is running, the BARO value is continually updated near WOT. A skewed MAP sensor will cause the calculated mass air flow value to be inaccurate and may result in a no start condition. The value shown for the MAP sensor parameter varies with the altitude. With the ignition ON and the engine OFF, 101 kPa is the approximate value near sea level. This value will decrease by approximately 3 kPa for every 1,000 feet (305 meters) of altitude.
