Question about Mitsubishi Lancer

1 Answer

I've got a Mitsubishi 2006 4G69 2.4L lancer. Very recently while starting for work early morning, the car suddenly lost power (did not switch off) after a couple of km's and would not let me rev beyond 2500-3000 rpm. I switched it off and back on again and still had the same problem it worked fine after 10-15 mins of rest. Happened 3 times till now. Not sure what to change very confused. The code P2138 came up everytime it happened. Please advice

    Thanks will see what I can do. Also like I said the check engine light came up and went off again everytime for the 2 times that happened and it does work fine now (been almost a week though not sure when this might happen again). Any chance of a loose wire? ALso where about is this located. Am also getting another set of codes as well. P0170, P0125, P0130. thanks

    With regards to the P2138, If there are loose contacts where do I look for one?? and if its corroded and needed to be replaced what are these sensors called?

  • fareed83 Dec 29, 2010

    Do i have to remove the sensor and check it or jus check the cable outside the sensor? Also if these are corroded what do I do? Do i need to replace the sensor? If so what are these generally called and how many sensors are there in it?? Thanks for the help and patience

  • fareed83 Dec 29, 2010

    When you say the connector, you meant the set of wires with a plug at the washer tank end (as per the image shown) is it?? thanks

Hello Fareed.

The code that is setting is accelerator pedal position sensor failure.
When this code sets it does a "failsafe" to prevent it from going full throttle.

TROUBLESHOOTING HINTS (The most likely causes for this code to be set are:)

  • Accelerator pedal position sensor failed or maladjusted.
  • Open or shorted accelerator pedal position sensor circuit, or connector damage.
  • ECM failed.
  • PCM failed.

There are several required special tools for this repair. The average handy man usually won't have these available.


MB991958: Scan Tool (MUT-III Sub Assembly)

MB991824: V.C.I.

MB991827: USB Cable

MB991911: Main Harness B

I would highly suggest you take it to a mechanic capable of doing this repair for you.

Thank you for using FixYa.

    Loose wire? Possibly. Also water inside it or corroded terminals. My experience has been the sensor itself internally.


    DTC P0125: Insufficient Coolant Temperature for Closed Loop Fuel Control
    This is probably a stuck open thermostat. Engine running too cold.

    PO130: front oxygen sensor heater circuit.
    Could be a fuse for the circuit but it's usually the sensor itself bad.

    PO170 ???? Not listed for this model.


  • FUBAR Dec 29, 2010

    They are called accelerator pedal position sensor.
    Look for loose or corroded connections on the sensor itself.
    It's mounted under the hood. Here is a location diagram for you.




  • FUBAR Dec 29, 2010

    I would recommend you replace it.
    Buy a new one and you will then see what it is you need to replace.
    If you do see corrosion when you pull the connector you may need a new connector for it as well.

    The sensor is called......Accelerator pedal position sensor

  • FUBAR Dec 29, 2010

    Yes Fareed, that is correct.

  • FUBAR Dec 29, 2010

    You are quite welcome.
    Thank you for using Fixya.

Trouble Starting the 2003 Mitsubishi Lancer


The most common cause for no crank is the neutral safety switch.
On automatic trans cars it keeps you from cranking the engine in drive or reverse. On manual trans cars you have to push the clutch in.
I would want to know if the starter is getting power from the key switch when the switch is in the start position.
