I had got a check engine light on. The code on IID tool is P0173-00 (EC) Fuel trim (bank 2). What can be the possible reasons for it. Please advise the fix for it.
Also I accidentally reset it without any action, the check engine light is gone for now. If there is really a problem, will the engine light be back again?
Mine is 2015 Range Rover Sports V6 HSE Petrol
Thank you in advance.
