Engine fault

Hi All. Engine light came on on my 07 SC. Got the IID tool on it and it says left bank too lean. Cleared the fault but it keeps recurring. Obviously cos the fault isn't rectified. Car is well and regularly serviced and does motorway miles all week so the engine is clean, and spot on.
Any ideas? Tony

Can be all sorts tbh.. vacuum leaks, Pcv system,bad maf sensor ect. Start with the obvious like the Pcv hoses. General inspection on them and maybe a smoke test to find any leaks

All hoses seem good. My son is a mechanic and he's checked, but I just thought there might be something obvious! Don't think it's the MAF as it is only registering the fault on one side and the MAF is a single intake into the SC. Thinking perhaps Lambda sensor???? Tony

Could be a sensor but knowing a rangey it could be a multitude of things..if you have done a smoke test and tested the fuel trims /fuel pressure/ fuel filters good and alls well then a sensor would be next on my list..

I didn't check voltages to be honest, but I had a new battery fitted in March. Tony
