Hi can only say use a quality/genuine kit with dephaser pulley and in my opinion you must replace water pump. It would be false economy not to as it forms part of the tensioning system and if it failed would require all same work to be done again, even if it didn't wreck your engine. £200...

Hi, this is always a risky process trying to diagnose a car over the internet, but here goes!! (It's hard enough sometimes when you have the car and the kit!) From the codes given I cannot see (at this point) issues with the throttle or throttle body (unless other codes relating to these have...

Can you get hold of all the codes saved (and pending) and post on here? I'm interested to see if there is a "thread" of issues. The problem is that the codes you focus on make sense as being the problem, mask the underlying issue. Are there any other codes that are NOT engine related?

I might be wrong, but as I said towards the start of this thread, our Clio came up with both throttle and throttle body faults (together with MAP sensor) and was none of these. It would be unlikely to be both of your components - my guess is that there is another underlying issue.

Hi, you cannot be 100% certain (especially from a distance) but it appears your Clio is throwing up codes associated with the throttle pedal/potentiometer and the throttle body. In my limited experience it is unlikely to be both and possibly neither! I can only reiterate what I have already said...

Hi, really sorry to hear. In short the answer is yes. Almost certainly an electrical fault, otherwise the car wouldn't put the lights on. Our Clio went into limp mode and both lights were illuminated. The problem is that whilst the fault codes will be stored in the ECU, the codes stored may or...

Many thanks Steve - will think about it, but the air-con wasn't working before this fault anyway - so a bigger issue than just sensor. If we get a good summer will get it looked at. Thanks again

Hi Steve, no it can't really as the short that is evident would still be there whether the sensor was disconnected or not. Please remember it was showing a 5V reference fault/short which has now been cleared and not reappeared. Secondly, when the car is scanned (Search System) it now knows the...

Hi Steve, that switch is correct one. It is definitely switch which has short as if it was wiring or anywhere else on car, the codes wouldn't clear.

Very many thanks, but would just reiterate one point. If the vehicle is going into limp mode (and even if it subsequently comes out) there will be a fault stored in the ECU which will not have been cleared, just because the event has gone away. Very best of luck - really frustrating issues.

Hi Steve, will dig out the wiring diagrams we managed to locate and as importantly the legend/descriptions we found. With regards to our fault, yes, the fault/code will be sorted when we replace the sensor. At the moment its just left disconnected. Best regards - Tony

Hi, for what its worth will try and give some ideas from our similar experience. Intermittent problems are the most frustrating, but from the little info available I would say following: - 1) If you have that triangle light on the car/ECU knows it has an electrical issue - component or wiring...

Hi Steve, that's the one! I will have to come back to you about the three wires/wiring code if I can locate the wiring diagram we downloaded. All we did was disconnect this sensor and it finally allowed us to clear the engine codes which had placed the car into permanent limp. The air-con was...

Hi Steve, many thanks. It's not shown on this photo, but is located in front of the air box air intake pipe. Had we not taken out the air box, we wouldn't have seen it. I can photograph our car if it helps, but don't know if this is universal on all similar models.

Many thanks for the help with this one - really appreciated. We finally tracked the problem down to a faulty pressure switch on the air-conditioning condenser! Just for others benefit, our learning points are, if you get several sensor faults that won't clear (and the 5V reference issue) it is...

I have replaced the dephaser, timing belt and water pump on a 172 and would just make the following observations: - I had not done one before, but took well over the 6 hours that the specialists can do the job in. Its really not difficult, but access is really limited. As for parts, personally...

Very many thanks for rapid response - really appreciated - will check tomorrow. Thank you again

Hi, I'm new to forum but wonder if anyone can point me in a direction with this? Car went into limp mode last week. Had the car diagnosed and came up with following codes:- Track 2 of throttle pedal Map sensor fault Induction damper 5v reference circuit We have switched throttle pedal, MAP...
