Check injection and power loss

[AbdoH]

Good day, am a clio rs 200 owner.
Am experiencing a major loss of power with my car, and today the “check ignition” and “check ESP” went on. Anyone experienced that problem
PS: I have recently changed the lambda sensor, spark plugs, and checked the fuel pump pressure.

Thank you

You had it plugged in to decent diagnostics yet?

 

[AbdoH]

Yeah sure, it was diagnosed at Renault’s dealer few days ago. am going back today to check on the injection prob

Diagnosed with what though and this is something you left out of the original post, why?

If you need help we will all try our best to give it but we need the full story matey.

First of all I was experiencing a loss of power; the car was really slow; I took it to the dealer and did a diagnostic. I was told that the problem was the lambda sensor, so we replaced it.
But the problem was not solved.

And today when driving normally the “check ignition” and “check ESP” warning lights on the dash went on.

Okay so we've most likely got two issues then (maybe linked?). As the main one is lack of power I would opt to start here and as the "Check Injection" message is on a code, and most importantly, context data has been flagged and memorised so back on CLIP it should go to have this looked at by someone that knows what they're looking at.

Some people in the trade dismiss CLIP but it does things that no other diagnostic kit out there can on Renault vehicles... mainly it can carryout a range of wiring and data network tests which can tell you if there are any wiring faults and more importantly between which nodes the fault is occuring and then it can also read Renaults sub-code system which is invaluable in cases like these.

So to sumerise (lets start simple):

1 - identify the actual fault first in both systems.

If they're linked (eg. Communication fault) then look to a possible wiring issue. If one is for example, low power and the other is a sensor issue check the systems power levels and then the actual alternator/battery voltages and go from there.

Report back
