Engine Managment Light

[Guest Keithf]

Hi all im new to these forums and have a question that i hope you can answer for me.

 

have a xara picasso 02 reg and recently the engine managment light has come on and the guy at the garage checked it with his machine ( free of charge im happy to say ) and anyway he said it was something to do with air intake or filter????? anyway iv changed the filter but light still on. just got me a haynes manual to try and learn about my car but not sure what im looking for so was hoping someone could give me some help with any ideas.

 

thanks

I had same problem with my car, 02 plate 1.6 eml can't on. The car felt like it was misfiring so replace the coil pack spark plugs services it twice. So bought fault code reader of eBay really cheap came up with fault code p1070 air and fuel trim. ok. I changed the maf sensor, coolant temp sensor clean the throttle body, cleaned all the wires and connecters. Change air filter. Nothing, then the car started cutting out without any warning. Fault coded again found to fault codes p1070 fuel trim and p1327 same problems has the first code. The car got worst cutting out round bends and straight roads so changed the relay next to ecu. ( red/brown box) cause thought that was the problem. Well after endless weekends of trying decides that the car was unsafe for the road and scaped it. Wasn't safe for someone with kids. So maybe if you try some of the things I did it may hopefully will work. Finger crossed and good luck

Rather than a cheap code reader, one that gives live data or a Citroen Lexia or a dealer diagnostic check would help point you in the right direction as opposed to replacing lots of bits hoping to find a fix. P1070 could be a faulty lambda sensor in the exhaust - live data would have shown if it was switching properly and whether at fault. Similarly, live data would show the temperature indicated by the coolant temp sensor so you could tell if it was faulty. Cutting out could also be a faulty crankshaft position sensor, particularly as it gets warm and making it difficult to start again until cooled down.
