    Default Peugeot 407 throttle body?

    Hi everyone.

    The car's Peugeot 407, 2004, 2.2 petrol, EW12J4, ~150К on the clock.

    The car goes into limp home mode after starting. Shows Engine fault : repair needed on the dash and has the following error codes in the ECU:

    P1153 Throttle stop programming.
    P0123 Motorised throttle signal 1. Short circuit to positive or open circuit.
    P0121 Throttle/Pedal Position Sensor/Switch "A" Circuit Range/Performance
    P1134 Throttle motor position sensor 2
    P1161 Throttle position check. / Throttle position captor, check. Coherence.

    I've checked the fuses, they're fine. Disconnected all plugs from the throttle unit, they look ok. Disconnected the battery.

    Am I right thinking I've got to buy a new throttle body? Anything else I should check prior to that?

    If I decide to turn to wreckers, what other model do have this engine/throttle body?

    Thanks.

    It's entirely possible.

    Here's a disturbingly similar story on Peugeotlogic

    I'm reasonably certain that, sadly, the 407 was the only Peugeot/CitroŽn sold in Australia with that engine and therefore, that throttle body.

    If sourcing one from a wrecker, you're looking for a VIN with a 3FZ or 3FY in it.
    Regards,

    Thank you, I've seen that link already. And VIN tip is quite good though 2.2 petrol seem to be quite rare at wreckers. Unlike diesel ones that are everywhere.

    The part number is 1636.15 by the way.

    It does appear that you can get them on eBay, and EAI here in Australia even have one on eBay.

    Yeah and there are plenty of them on eBay in UK. $400 shipped via DHL express (which is same 3 days as local AusPost). Not a big deal but I just want to ensure it's the unit itself, not not the loom or something like that. Hence the question.

    Have you checked the coil pack thingy (sorry the description escapes me). I had similar issues and one of the plugs was not firing correctly, So i had to replace the whole unit.

    Thanks mate. I'll check the loom and all related wiring and some other things over the weekend. But I'm almost certain I'll have to buy a new throttle unit and thus will contact you soon.

    Did you also have a bunch of error codes related to throttle body? And how do I check the coils/coil pack?

    You also got this error:

    P0121 Throttle/Pedal Position Sensor/Switch "A" Circuit Range/Performance


    Have you eliminated the TPS? I believe it's integrated into the throttle pedal, and can put car into limp mode if faulty.

    Cheers

    Not yet, I'm just getting some ideas for the weekend. How do I tell TPS issues from all the other stuff?

    Sorry - I only know what I read on this forum . I know others have had problems with the throttle/accelerator pedal sensor (not just on 407s, but on Cit C5s I think), but I don't know how to test it or how to replace it.

    Cheers

    So I took the throttle unit off and low and behold, the gears are shattered (as per one the links above):


    Time to replace it.

    Well I'll be...

    Great diagnostic work! Hope the replacement isn't too expensive.

    Cheers

    Not exactly Moggil, but I guess it's that one, yes.

    This sort of failure seems to be fairly common. Plastic gears aren't really known for their durability.

    As mentioned, thanks for posting up your findings. It will be a reasonably pricey fix, but hopefully it helps others too.

    New throttle body is 400 AUD shipped on eBay. And 15 minutes to install it back.

    So I got a replacement throttle body (thanks Balki), installed it, then followed the procedure that supposedly initializes the throttle. And all's good.

    For anyone curious, this is the procedure found on the internet:
    1. Turn on ignition (do not start the car) for 30 sec
    2. Turn off ignition for 30 sec
    3. Turn on ignition (do not start the car) for 30 sec
    4. Turn off ignition for 30 sec
    5. Turn on ignition then slowly push the throttle pedal to the floor, kepp it like that for few seconds
    6. Turn off ignition
    7. Start the car

    Not sure if it works, but lot's of people claim it helps them with intermittent errors and issues.

    I was at KMJ Wreckers at Sumner Park earlier in the week picking up some interior trim pieces for my 407. They have a 2.2L petrol 407.

    What did you end up paying for the 407? I was going to go and see it as I live around the corner, but couldn't tee up a time with the woman. Is it a keeper or are you going to sell it?

    You can also use Lexia for throttle body alignment.

    I wish I knew that earlier. But anyway sourced the part from this forum.

    $1400 plus towing. Also had to fiddle a bit with ABS sensor. "Professional" mechanic who replaced the fuel pump forgot to plug the sensor back in. I'll keep the car for my wife. It's in good condition though it would need a service and probably a major one.

    I'll probably do that once the car's back on the road.
