Clio won’t start I have the solution!!

[LoopyLou]

I have had a few problems with intermitant starting problems with my Mk1 172. I had 4 people look at it each with different ideas to the solution to the problem including immoboliser, relays etc. But the clever AA man worked it out.....

.....a dirty crank sensor! he just cleaned it up and the car is working perfectly now. I suggest anyone that has the same problem with intermitant starting problems checks it. Its just under the air filter and is worth cleaning. Might save you some headaches.

What does this sensor do???

 

[LoopyLou]

It senses the motion from the flywheel and sends the message to the fuel pump, injectors etc to start the car

Hmmmmm, Do you know if the sensor applies to a mk2 172? I have been having similar starting issues. If so is it a easy thing to get at???

yep a common failure on all renaults that is.

well worth checking, its usually the connections that fail.

On the Mk1 its quite easy to reach - I doubt the mk 2 is very different. The air filter has to come off, and then on the left, quite far down there is a black square, thats the sensor, there are two bolts one either end on the square, unbolt it and clean it. Apparently it is more exposed than on other cars so its a common problem for it to get dirty and stop working on clios.
