I'm new here and this is my first post, so hi everyone and thanks in advance for reading.
I recently acquired a 2003 Vectra C Y20DTH. Thought I had got myself a bargain, only 68k on her. But alas, things were not as good as I had first hoped. The car drove perfectly at first but after a number of days I got chugging and a loss of power with the spanner appearing on dash.
I had my mechanic run diagnostics and it showed a fault on the Throttle Position Sensor and a Clutch Sensor fault. At this point he point he pushed the pedal to the floor with the engine not responding at all. He said he would locate another accelerator, which he did the following day. In fact he sourced two to try. No joy, same fault.
What was worse was when he replaced the original pedal it was clear that it had already been replaced, meaning that someone else had already attempted to resolve this issue.....and failed!!!
Cut a long story short, my mechanic thinks that the problem lies with the ECU and on this model that's attached to the fuel pump and it's generally an expensive fix.
Now I know my mechanic will give me a fair price on labour and I think I've located a reconditioned ECU /pump at a reasonable price but it's still expensive and from reading some similar problems on here I wanted to be sure we haven't overlooked a simpler fix.
So my questions are
Has anyone fixed a throttle position sensor fault by another method other than replacing the pedal or ECU?
Some other posts mention a dry solder on the throttle body, how likely would it be that's the culprit?
Thanks for reading
