Hi All,

I just got my 2015 F-Type R back after getting my front tires replaced due to a nail in one of them that couldn't be fixed. As I was pulling into the service bay my check engine light came on. When I got home I tried to scan it, but the ODB2 scanner said the vehicle isn't responding. I tried with the car started and also in On (not running). I tried under Jaguar mode and Generic ODB2 mode with no luck. I have a car club drive to Borrego Springs I am co-leading tomorrow and wonder if it is safe to take the car?

 

You might want to check and see if the fuse for the OBD port is good - ISTR that can cause problems with scanners. You did turn the ignition on though right ?

 

Yes, start button pressed w/o brake depressed - engine not running and also tried with engine running. Where is the ODB port fuse? Car has slightly less than 10K miles on her.

 

According to my handbook it is Fuse #1 in the engine compartment (5A Tan) for Diagnostic Port

 

Thanks for taking the time to find the info. It didn't dawn on me to check the manual.

 

Fuse is fine. I'll need to make an appt to take it in. Per manual it is emissions related for the CEL. Can be driven, but may go into Limp-Home mode. Bet it is the O2 sensor since that seems to be a thorn in the cat's foot.

 

You might physically inspect the OBD2 connectors on the car and your scanner.

 

Try a different code reader.

 

One of my buddies borrowed the scanner a few weeks ago and worked fine for his Mercedes. I'll try one of my other cars. Seems to go into the F-Type OBD Port fine.

FYI to prev post.. Fuse for 2015 F-Type R OBD port is #15 in engine bay per manual.

 

Try tightening the gas cap - remove and put back, turn at least 3 clikcs then drive for a few miles. I have had the CEL once and this resolved it.

 

I filled up gas on the way back home and CEL was still present when I got home. Shutdown the started again... Waited a couple of hours to let cool and still CEL. I always click several times. Wish it was the issue.

I am riding with one of the other club members tomorrow and I will be navigator. Made an appt for next week with dealer service.

 

I brought the car into the dealer today. First thing they asked if I had put a code reader on it. The Service Writer (SW) said that causes issues (hmmm). He said the CEL code was for the evap system. He stated since I have a 3rd party gas cap (the locking one that most of us have) that it may not sealing and causing the issue. I told the SW that I've had the cap on for 2 years without issues. He wants me to put OEM gas-cap back on and see if code reappears (they cleared the codes). I am kind of leery about parking the car with unprotected gas-cap. He said this is the only way he can move forward and look for other causes if they eliminate the gas-cap as the issue.

 

How often does anyone tamper with the fuel tanks in your area? I haven't heard anything about that for over a quarter century. I suspect most miscreants just assume all fuel tanks are locked.

 

Only takes one miscreant to make ones life a little tougher. I may be overly cautious.

 

Gas cap seal could have failed after 2 years - age / wear & tear. Who knows what the quality of the cap is.

Replacing the cap is an easy fix to try - if it goes away after a couple of days you know that is the issue, if not the dealer can continue their troubleshooting.

I don't think I have read one report on here of an owner having had their gas tank tampered with, personally I consider the risk to be almost negligible .

 

I'm with Unhinged and ek993; I don't have a locking cap and don't really care, I agree that the risk is very, very, very small. FWIW, neither of my MB's have locking caps either.

Put the stock cap back on and see what happens.

2 cents,
Dave

 

Good points. I misplaced the OEM gas cap when I moved into my new house (somewhere in many boxes), so ordered a new OEM one off of eBay. Hopefully CEL doesn't return prior to getting the replacement cap.

 

I could not find a locking cap in the US or GB that fit the F type. Had to return them.

 

even if it does, the light will reset after several starts if the new cap resolves the problem.
