Dear Mr. XOIC.

If your Waja 1.8 error code is 'throttle potentio circuit' error, just ask your mechanic to service or clean the TB first, then please also check the wiring from TPS (throttle potentiometer sensor), TB (throttle body) and to the ECU.

There are 6 wires from the TB and TPS to your Waja ECU. My mechanic found that the socket/plug to my ECU was a bit oxidized with white powdery residue. My problems so far have been gone for almost 2 years now.

Bare in mind that our Waja 1.8/ Renault f4p ECU (esp ind. module C and above) and TB are very hard to break-down.

Hope this may help you.
