Stalling Colorado? Bad Rail Pressure Sensor Alert

Had the exact same symptoms on my 2017 Chevy Silverado last month. The pressure sensor was indeed failing, causing incorrect sensor signals to the ECU. This made the engine run in "limp mode" to protect itself. It turned out to be a serious issue that needed immediate attention since bad readings from the fuel rail pressure sensor can potentially damage the fuel injection system. The diagnostic scan confirmed error codes related to fuel pressure irregularities. The repair involved replacing the complete fuel rail pressure sensor assembly. The engine performance returned to normal right after the fix, no more stalling, proper idle, and full power restored. The check engine light also cleared up. Quick tip: Make sure they check the wiring harness connected to the sensor too. In my case, they found some minor corrosion on the connector that could have caused future problems if left unchecked. The repair was straightforward for an experienced mechanic and took about 2 hours total. Definitely not a DIY job though, as it requires specific diagnostic equipment to verify proper sensor function after installation.

Wow, that's exactly what happened with my Colorado too! I took it to the shop and they also found it was the rail pressure sensor causing the engine stalling. Really similar to what you described, engine running rough, check engine light, the whole deal. Did you remember roughly what you paid for the repair? Mine cost a bit more than I expected, but wondering if that's just normal these days. Also curious if you've had any other engine performance issues since getting it fixed? Mine's been running great for about 3 months now, but always good to know what to watch out for.

Just wanted to update on the repair costs, the rail pressure sensor replacement ran me 240€ total. The mechanic confirmed it was definitely causing the faulty sensor signals and leading to those engine stalling issues we both experienced. The diagnostic scan showed the exact same error codes you mentioned. Since the repair, my truck's been running perfectly fine, no more check engine lights or performance issues at all. The fuel pressure is now stable and the engine idles smoothly. It's been about 7 months now, and I haven't had a single problem with the engine performance. The repair cost was worth every penny considering how critical that sensor is for proper fuel delivery. Make sure to keep an eye on your fuel pressure readings through the scanner if you can, that's usually the first sign if anything starts acting up again. But honestly, once these sensors are replaced with quality parts, they typically last for quite a while. The shop did a great job checking all the related components too, which probably helped prevent any future issues. Sounds like we both got the right fix, even if the cost felt a bit steep at first.

Thanks for checking in. Yeah, I ended up taking my truck to the mechanic last week. The final bill came to just under €300 for the entire job. The mechanic showed me the old pressure sensor when they pulled it out, it was pretty corroded and definitely needed replacing. They had the diesel engine up and running in about 2 hours. The check engine light cleared right away and the stalling completely stopped. Been driving it for a few days now and it feels like a completely different truck, smooth idle, no power loss, running great. Funny thing is, while I was waiting at the shop, another guy came in with almost identical symptoms on his truck. The mechanic mentioned they've been seeing quite a few failing fuel rail pressure sensors lately. Guess it's a common issue. Really glad I didn't wait any longer to get it fixed. The mechanic said ignoring these symptoms could've led to bigger problems with the fuel injection system down the road. Money well spent in my opinion, even though I initially thought the quote was a bit high.
