Engine light on with fault code

Postby sbtjap » Fri May 04, 2012 10:11 am

My Service Engine Soon light just came on. Took out my Renault CAN Clip Diagnostic Interfaceand the following codes came up: P1086, P1084, P0172, P0175. What should I be looking for when trying to fix this problem?

Hi,

Running too rich, fuel/air mixture. Thinking could MAF related. Is it worth cleaned the MAF with the dedicated MAF Cleaner?

Also make sure that the housing around air filter/MAF has no splits.

What megane are you running Petrol or Diesel

Regards

Tony

Is there a typo in the first two codes?

The last two are about too little oxygen detected by the O2 sensors. Look at the graphs of live parameters for the further analysis.
