Check Engine Light- gas cap

Get that message often on my Toyota Tacoma. Check your fuel cap. Your system checks (CEL) it if you "generally" fill up. It pressurizes it but ignores it when the fuel level is down and sees if the cap is loose. Could indicate possibly a "break" in the fuel system recovery canister device. Might also check if the "O" ring of the cap is OK too.

Ok. Yea some articles I read suggested changing the cap also

Usually it is only the "O" ring that is bad. Try looking at it and see if the gas cap is damaged or the "O" ring is cracked. You might try some grease on it which will last a week perhaps if you are lucky.

Get a new cap and make sure it is from Range Rover and not aftermarket.

I didn't have that issue but our tire pressure monitor light kept going on . we actually disabled it and get tire pressure checked every few months. Your issue may be fixed by getting new cap

How did you disable the tire sensor light?

Yes, Have spent $700.00 with the dealer in repairs to my low mileage 2011 RR Sport Supercharged, replacing "bad" fuel system parts, and yet the problem persists. The check engine light will remain off for about a week after the repairs, but will come back on. Spent another $450 with an independent Land Rover service company, same problem. Replaced the gas cap twice with OEM part and Range Rover part, still persists. Jerry Edwards lake elsinore ca
