Why doesn't my remote start work with the check engine light on?

I’ve been having some trouble with my Chevrolet lately, and I’m hoping to get some advice or solutions from those who might have experienced the same issue.

Overview
I’m noticing that my remote start feature doesn’t work when the check engine light is illuminated. Initially, I just assumed it was a minor issue, but I did some digging and realized that there are likely some underlying problems that could be affecting my vehicle’s functionality.

What I’ve Observed

  1. Check Engine Light: This light came on recently without any noticeable changes in performance.
  2. Remote Start: Every time I try to use the remote start, it simply does nothing. It seems to be tied to the check engine light, as I can’t use the remote start feature whenever it’s on.

Possible Causes
I understand that the remote start system can be disabled by a variety of issues indicated by the check engine light. Some common reasons might include:

  • Faulty Sensors: Sensors such as the oxygen sensor or mass airflow sensor can trigger the check engine light, leading to the remote start being disabled.
  • Battery Issues: If the battery is weak or failing, it might also cause the remote start issue.
  • Other Faults: Various other engine-related issues might also cause this light to illuminate, compelling the vehicle’s safety protocols to kick in.

Seeking Guidance

  • Have any of you experienced this with your Chevrolet?
  • What steps did you take to resolve it?
  • I’m also considering visiting my mechanic but would like to gather some additional insights first.

Conclusion
Any advice or troubleshooting tips would be greatly appreciated! It’s a bit frustrating not being able to utilize the remote start feature, especially in this cold weather. Looking forward to your thoughts and experiences!

Thanks in advance for your help!

When the check engine light is on, it usually indicates that the vehicle’s computer has detected an issue. Common causes can include sensor malfunctions or even something as simple as a loose gas cap. This can definitely interfere with remote start functionality.

Exactly! It could also mean there’s a more serious problem at hand, like engine trouble. I’d recommend getting it checked out soon.

Don’t forget that some vehicles will disable remote start as a safeguard if there’s a fault. It’s annoying, but it’s there to protect your engine! Check your manual for details.

Yes, that’s such a frustrating feature! If it’s just a sensor or something minor, it feels like overkill.

Agreed, it might be time to pull out the code reader if you have one. Issues like oxygen sensor failures or catalytic converter problems could also cause it to light up.

It’s a good idea to look into this ASAP. A check engine light could point to something harmless or severe. Don’t take chances with your car’s health.

If remote start isn’t working, it doesn’t mean you can’t drive it. Just make sure that the issue is diagnosed to avoid further problems. Do you have a mechanic in mind?

True! But my friend once had an issue that escalated because they ignored the light for too long. Better to address it early!

Honestly, sometimes it feels like the check engine light is just a suggestion! But it really could be a vital problem. Are you hearing any unusual noises from the engine?

Haha, right? But we know that’s not true! Keeping the car running smoothly is key to these fancy features working.

If your remote start isn’t working and the check engine light is on, it’s often a warning signal. Start by using an OBD-II scanner to read the error codes. This will help you pinpoint the issue.

It’s definitely a good idea to check those error codes first. Each code can give you a specific direction to troubleshoot. Anyone know where I can find a reliable OBD-II scanner?

I had a similar problem before! After scanning, I found out it was just a loose gas cap. Sometimes the simplest issues cause headaches.

That’s a great point! It’s easy to overlook simple fixes. What were the codes you got, Lisarussell?

I’ve used my OBD-II scanner for various issues. Once you have the codes, look them up online for better clarity. Often, forums are full of experiences similar to yours.

Definitely! And don’t hesitate to ask for help on forums. There are many knowledgeable users who can guide you through troubleshooting.

What if the issue is something more serious, though? It could be a malfunctioning sensor or even a problem with the engine itself. Best to catch it early!

That’s true, richard70. But starting with the codes gives you a clearer direction before diving deeper!

This topic reminds me of my car saga last month! The check engine light was on, and I thought it was serious. Turns out it was just a software glitch! Took me ages to resolve.
