207 1.4 ECU Pinout

Post by jjsmith1100 »

I have a 2007 207 1.4 8 valve. I have noticed that 4 pins in my ECU seems to be burned or something and I would like to know what they are for. I have searched everywhere but I don't seem to be able to find a layout of what pin is for what on the ECU. I did find a picture that mark these pins as plug T2 pins L1 L2 M1 and M2. Don't know if that helps. Its the centre plug on the ECU, top two rows, last for pins on the right hand side.

Pop your VIN up here for me and I'll be able to look at the circuit diagram for your injection. We should be able to sort this for you.

Ok, so ignore that diagram you had - that is for a Bosch system. You don't have that injection system - you have a Johnson Control unit.

I'm not quite sure what it is you want or what you are looking for - this is the Injection ECU diagram for your vehicle. 1310 is the Injection ECU

Hey, I stumbled onto this thread few days ago, used search function but didnt found any relevant answers to my problem, so need to revive thread. Would this wiring Diagram also work out for an 207 1.4 running on a Valeo V34.1? Some pins I already checked seem to be matching, but I want to make sure nontheless ^^ Also it follows my understanding that the pinout from the wiring looom, must stay the same regardless of ecu type ran. I can also post VIN if needed.

Diagrams are unique and specific to vehicle, engine, build date and options, so yes I'll need the VIN (please post your VIN in full without spaces - it will be automatically masked from public view after submitting your post & will only be visible to staff). You haven't mentioned which system you need - so I assume Injection, if not let me know at the same time.

Systems I need is quite alot, as im trying to wire up a VEMS ECU ^^, so pretty much all I/Os are needed :)
But I have found a lot of Documentation online for reading and interpreting the Wiring Diagrams.

I can't provide you with everything, but here is the injection ECU:

Thank you the Wiring Diagram was very helpful for my Pinout so far. But I encountered a few problems...

Is there information on the Pinout for the Ignition module?
Is there information of the exact wiring for A/C and Fan control?
Valeo ECU gets VSS from Component "1313", but does not specify on what pin it outputs Tacho (guessing 12V square) or does it use spark pulse?
The most vital part for me seems to be missing in the diagram, Crankshaft and Camshaft position or how it is called in Documentation: "TDC and Cylinder Reference Sensor"

Nontheless, again a big thank you for the help so far... Documentation is really spare and confusing on French Cars for some reason... ^^

1313 is the engine Speed Sensor.

Wire 1361 (Pin 1): engine speed sensor signal +
Wire 1362 (Pin 2): engine speed sensor signal -

I'll see if I can get the ignition / AC for you shortly.
