Citroen C4 losing power

(jw snipped-for-privacy@yahoo.co.uk) gurgled happily, sounding much like they were saying :

Go on, a rough hint... Petrol? Diesel?

On the face of what you say, a failing pedal position sensor.

Tim..

It's a petrol 1.4.....the basic one

Thought about that....it (apparently) has two sensors that choose the 'correct' position if one fails - scary. Whatever was wrong with a cable? Or am I showing my age.................

But you might be right!

Yes, there are two tracks, in most cases, one ranges 0-5v, the other 3-8v or there abouts. The ECU monitors both and chooses a 'sensible' amount of power from that, based on several other things.

Cables are old hat. Need many fixtures and fittings at both ends, whereas with a sensor at one end and motor at the other, you only have effectively 2 moving parts. (and yes, a greater propensity for failure!)

Tim..

Aye, I can remember driving home with a piece of string to pull to operate the carb. (remember those) in the days when everything was fixable, mind you, things did seem to break more often too, but at least they were fixable or temporary bodgeable.

Yeah, you could mostly cure any none HT drivability problem with a can of carb-cleaner, for about £3 at home.
