    Default Fuel Cut & Check Light on (CS5 GDI)

    Hi Guys,

    Sorry I havent posted in awhile on these forums but Im at a loss as to whats happening with my CS5 and would appreciate any assistance.

    Its a CS5A with GDI engine, everything is stock except for a K&N drop in.
    I'll be driving around (2000rpm) and the engine light would come on and the fuel delivery would cut. At least thats how it feels.
    I would mash for gas and not go anywhere.
    Flooring the pedal would get me to 2000rpm and a very slow creep over to the side of the road.

    Idle stays the same, no fluctuations, check light would remain on.

    If I take off the car for about 30secs and restart, it works normal and the check light comes off.

    The error code reads:
    "P0220 Throttle/Pedal Position Sensor/Switch B Circuit Malfunction"

    I have changed the throttle body and the problem stopped but it started back today.

    Its electronic throttle so im thinking its either the sensor on the pedal or the throttle body.

    Did this happen to anyone here?
    Or can anyone assist in diagnosing my problem.

    Thanks

    Try to check ur Pedal Position Sensor.. If you know any CS5 friends can swap with them and test it out.

    BTW, how high is your boost ?

    Or rite, sorry I forgot to mention im N/A

    Jus a regular 4G93 CS5 sedan non-turbo

    There arent much CS5's here otherwise I wouldve tried that

    We mostly have CS3's with 4G18s and CS2's

    Can a CS2 pedal be swapped?
    The CS2's here have the 4G15 GDI e-throttle

    If i am not wrong, you could use CS5 turbo pedal.. Should be the same model..

    Its very hard to find a 4G15 GDI here..

    thanks MZSport

    Every other Lancer here is a CS2A...very very rare to find another CS5A
    More common is the CS2W then the CS5W, turbo CS5W is a gem to spot

    Ok so Ive been doing some really extensive searches and I remember the car throwing two codes: P1225 and P0220

    Online search show the P1225 as a Fuel/Air Metering Problem and P0220 as TPS.

    I found a MMC manual which states otherwise:

    P1225: Accelerator pedal position sensor (2nd Channel)
    P0220: Accelerator pedal position sensor (1st Channel)

    Theres a diagram that shows 1st channel goes to the ECU and the 2nd channel goes to the Throttle Valve Controller.

    Now I unplugged the Pedal Sensor and the idle went up to 2500 and was erratic sounding like a subaru engine. Definitely not the same when it happens while driving. So Im wondering if wires are short circuiting or if the ECU needs changing.

    So far I scrapped everything and cleaned all the sensors with Electrical CRC
    and checked all the wires for breakage.

    Its driving normal for now, but will update if it changes
