Intermittent starting

[Alfie76]

​Hey guys, I have a 2001 ph2 with intermittent electrical/heater plug light which comes on when I try to start car, turn key off try again & light goes out & cars starts, crank sensor maybe??Any ideas please?

If the light comes on does the car actually start ? Does it go in limp mode ?

Most common problem is the crank sensor, assuming you know where it is (and it is the problem) just give it a wiggle and that will sort it out

Was just about to get to that but crank sensor doesn't usually cause light to come on. TP sensor does though...

Thanks guys, no car doesn't usually start with light on however it has once & I 'think' it was limp mode as car was running but not as normal with revs at a constant 2.5k so I turned ignition off & car started fine again?!?!

Could be faulty Throttle position sensor. bolts to the side of the throttle body.
, Tells the ecu the location of the paddle. Had the same though of issue on my Clio 1.2
