2013 Chevrolet Silverado 1500 — check-engine light turned itself off — still scan it?

RoadWrench173Community StarterMay 18, 20262013 Chevrolet Silverado 1500 LTPhiladelphia
The light was on for two days and then disappeared before I could schedule service. Car feels normal. Is there still likely to be useful stored or pending data if I scan it now?

I wouldn't throw parts yet. Loaded-suspension checks on the 2013 Chevrolet Silverado 1500 catch play that a wheels-hanging inspection misses. That's the branch I'd chase this week. Any freeze-frame data saved? Worth doing even if the car feels fine right now. Happens in gear, not in park, for what that's worth.

Tried a second charger / second scan and the story on the 2013 Chevrolet Silverado 1500 didn't change. I'll poke at it this weekend.

Ask what changed right before it started. Get a real battery/charging test on the 2013 Chevrolet Silverado 1500, not just resting voltage, before blaming a module. You'll know quickly if you're on the wrong tree. No need to make it theatrical. Next check is the cheap one I can do in a driveway.

I'd want a measurement, not a hunch. Capture voltage while the 2013 Chevrolet Silverado 1500 is actually failing — after it restarts you've lost the clue. If the cheap test changes it, stop and reassess. Was this after sitting overnight? Not trying to scare you — just skip the expensive first guess. Parking it somewhere I can hear it better next time.

This is usually cheaper to test than to guess. Move a coil or plug on the 2013 Chevrolet Silverado 1500 if it's cylinder-specific and see whether the code follows. If the cheap test changes it, stop and reassess. If they can't show the line item, I assume it's hiding. Next check is the cheap one I can do in a driveway.

Intermittent stuff lies if you only catch it once. Get a real battery/charging test on the 2013 Chevrolet Silverado 1500, not just resting voltage, before blaming a module. Save the big job until that test fails. On “check-engine light turned itself off — still,” that was the fork that mattered for me. Write the result down so the next test isn't a repeat of the last one. This is the filter I use when the thread starts repeating itself. Heat soak after errands is the other window.

Yes, with one caveat: Two 2013 Chevrolet Silverado 1500s can feel identical and have different causes, so measure before you copy someone else's repair. Save the big job until that test fails. This is from a 2013 Chevrolet Silverado 1500 in Philadelphia. Verbal 'we'll take care of it' is not a plan. Happens in gear, not in park, for what that's worth.

Asking because it changes the advice: Write temp, speed, and in-gear vs coast when the 2013 Chevrolet Silverado 1500 does it — then decide on parts. Save the big job until that test fails. This is from a 2013 Chevrolet Silverado 1500 in Philadelphia. Have you gotten a second quote in writing? No warning lights, which is why I'm documenting it.

Log the conditions before you spend. If a shop can't duplicate it on the 2013 Chevrolet Silverado 1500, bring a video plus freeze-frame data, not just a story. Don't erase codes until someone who can help has seen them. On “check-engine light turned itself off — still,” that was the fork that mattered for me. This is from a 2013 Chevrolet Silverado 1500 in Philadelphia. That's the whole play. That's my plan before I call anyone.

Checked the easy stuff on the 2013 Chevrolet Silverado 1500 and found one clue worth chasing before I book a shop. If that fails I'll eat the diagnostic fee.

OP update: scanned the 2013 Chevrolet Silverado 1500 again and still only have the one pending code, no new lights. I'd rather pay for diagnosis than a second guess-repair.

Start with the test that can prove you wrong. Write temp, speed, and in-gear vs coast when the 2013 Chevrolet Silverado 1500 does it — then decide on parts. If the cheap test changes it, stop and reassess. Keep sale price, fees, and rate as three different conversations. Doing the boring step first on purpose.

That's the branch I'd chase this week. I'd want that in writing, not as a promise. I'd sleep better after that step, even if it finds nothing. I already checked the easy fluid levels.

Start with the test that can prove you wrong. A pressure test beats staring at a dry driveway if the 2013 Chevrolet Silverado 1500 is losing coolant with no puddle. If the cheap test changes it, stop and reassess. Learned this the expensive way on a previous car. If this is nothing, great. I want that in data.

Fair point. Counterpoint: Get a real battery/charging test on the 2013 Chevrolet Silverado 1500, not just resting voltage, before blaming a module. Save the big job until that test fails. When does it actually happen? I'm in no rush to be a hero on it.

If it were in my driveway, loaded-suspension checks on the 2013 Chevrolet Silverado 1500 catch play that a wheels-hanging inspection misses. Save the big job until that test fails. This is from a 2013 Chevrolet Silverado 1500 in Philadelphia. Time, temperature, and whether it's in gear are the notes that actually help a shop. Wrote this up on my lunch break.

You'll know quickly if you're on the wrong tree. If it doesn't change the out-the-door or the repair estimate, it's noise. Make the next action something you can finish this week. Not driving it hard until I know more.

I keep a notes app thread for this now.
