Seeking Solutions for Check Engine Light and Faulty Fuel Tank Flap on 2020 Nissan Navara

Check engine light on

Fault stored

Warning light in the speedometer of the vehicle

Hey gearheads! I’m having a bit of trouble with my 2020 Nissan Navara (Gasoline) - odd behavior I can't quite nail down. The check engine light's on, there's a warning light in the speedometer, and I noticed a fault stored. I've a hunch it might be something off with the tank flap not unlocking correctly, but I thought I'd tap into your collective wisdom here before I dive down that rabbit hole. Got any thoughts on this? How have you tackled similar problems before? Particularly keen on hearing about your workshop experiences and how you got it sorted. Cheers!

Hey there, I had a very similar issue with my 2018 Nissan Titan that drove me bonkers. I only have some level of experience with car troubles, nothing too fancy. Mine also had the dreaded check engine light and a warning, turned out the Linkage was defective. I took my ride to my trusted local mechanic, a really chill but clever dude. He did his magic, and it cost me a modest 210 Euro to fix it up. It's worth mentioning that the diagnose and fix might differ based on specifics of your car. Could you share more about the warning light and the fault stored? That might help guide us a bit better. Stay safe!

Hey, appreciate you chiming in and sharing your experience with the Titan. My Navara, with about 130971 KM on it, hasn't been to the garage since the last oil service. The warning light is a generic "service required" signal, but I think it's more than that since the tank flap has been playing up. The fault stored was something about "Evaporative Emission Control System Incorrect Purge Flow". Quite a mouthful but I have no clue what it means – any ideas? Could it be related to the tank flap issue or is it a separate thing altogether? Cheers!

Hey, the rabbit hole goes deeper, doesn't it? Your mileage there isn't necessarily a warning sign, but it does mean your Navara has been around the block a few times. It could very well be related to the tank flap issue you've mentioned earlier. So, here's the tech bit: the "Evaporative Emission Control System Incorrect Purge Flow" fault is linked with the fuel system. Basically, the system captures and temporarily stores fuel vapors from the fuel tank before sending them to the engine for combustion. A purge flow error could hint towards a blockage or a leak in the system which can trigger the check engine light. Now, the tank flap not locking correctly might be a symptom or a cause. If it's not sealing properly, it could allow those fuel vapors to escape, triggering the fault. On the flip side, if the problem is elsewhere in the system, the pressure changes might be affecting the flap lock. It's a bit tricky to diagnose precisely without getting hands-on, so I'd recommend taking your truck to a mechanic. In my experience, this isn't typically a wallet-buster of an issue, but better safe than stranded. Keep us posted! Cheers!

Great stuff, that's really helpful to know. I wasn't even aware of this "Evaporative Emission Control System" thing, but it most certainly sounds like it could be connected to the tank flap issue I noticed. She's indeed been around the block quite a few times, so I guess I shouldn't be shocked at some new issues cropping up. I think I'll follow your advice and get it to a garage with a decent mechanic to check it out. I really wouldn't want to mess it up trying to fix it myself. I'll keep you updated on what's what once things move along. Thanks again for your insights, really appreciate it. Cheers!
