Could you have an air leak? I had a CEL and after retightening all hoses and resetting the ECU - no CEL.

Hey guys
It's been 3 months and I had my 50k service and a ECU update and the CEL keeps popping up

P0132 Fuel Bank Cylinder 1
Left Bank Lean

Mazda Dealer has no idea what it might be. They said after the service if it come back on to leave it with them for 4-5 days so they can monitor what is actually causing the problem. They said we know it isn't damaging the vehicle, but just hate knowing that there might be a problem

Plus I'm a bit hesitant to leave it with since the Service Manager at Garry & Warren Smith Mazda Mulgrave has defected to Berwick Nissan. He was fantastic and honest and always had time for a chat.

Anyone else had this CEL code or this problem? Everytime its cleared it pops up 1-2 days later

Do you have an intake or downpipe?

Tried cleaning your MAF sensor Pete? Might be a long-shot, but from what I can see something's telling your ECU that the engine is running lean (one of the O2 sensors near the cat maybe?)

If your MAF sensor is dirty, it could be feeding inaccurate data to the ECU about the actual amount of air flow into your engine (ie not metering all of the air passing through) and in turn the ECU isn't feeding enough fuel in to match the actual air rate

Just a thought

Went to visit LoopyMPS who had a OBDII reader.

New code come up
P0171

Any clues guys?

means you're running lean

Thanks mate. I will do that from now on!

We cleared the code and cleaned the MAF sensor and air filter

Gonna see what happens after a few days and then speak to Mazda

Edit:
Thanks to the advice above, found this website:

Might have fixed it with the cleaning of the MAF and air filter
