P0016 and P0017 Codes on Chevy Equinox - What Now?

Understanding P0016 and P0017 Codes

If you’re dealing with P0016 and P0017 trouble codes on your Chevy Equinox, you’re not alone. These codes often indicate a problem with the correlation between the camshaft and crankshaft positions. Let’s dive into what these codes mean, potential symptoms you may be experiencing, and how to troubleshoot and resolve the issues.

What Do These Codes Mean?

  • P0016: This code signifies that the Engine Control Module (ECM) has detected a mismatch in the camshaft position sensor and the crankshaft position sensor.
  • P0017: Similar to P0016, this code indicates a correlation issue but is specifically related to the exhaust camshaft.

Symptoms to Look For

When these codes trigger, you might notice:

  • Poor engine performance
  • Increased fuel consumption
  • Engine stalling or rough idling
  • Check Engine Light illuminating
  • Possible noise from the engine

Troubleshooting Steps

  1. Check the Sensors: Inspect the camshaft and crankshaft position sensors for any signs of wear or damage.
  2. Wiring Issues: Check the wiring and connectors for corrosion, disconnection, or short circuits.
  3. Timing Chain or Belt: Make sure the timing chain or belt is aligned correctly. A misaligned belt can often lead to these codes.
  4. Oil Flow: Check the oil flow, as these sensors can be affected by low oil levels or dirty oil.
  5. Faulty Components: Sometimes, replacing the sensors or solenoids related to these codes is necessary if they are found to be faulty.

Potential Repairs

  • Sensor Replacement: If the sensors are faulty, replacing them usually resolves the issue.
  • Timing Adjustment: In some cases, adjusting the timing or replacing the timing belt can fix the problem.
  • ECM Reprogramming: If everything checks out but the codes persist, the ECM might need reprogramming or replacement.

Maintenance Tips

  • Regularly check and change your engine oil to ensure proper lubrication of engine components.
  • Keep an eye on the timing belt or chain’s condition and timing to prevent issues before they start.

It’s essential to address these codes promptly, as ignoring them can lead to more severe engine damage down the road. If you’re still unsure about tackling these problems yourself, consulting with a professional is always a good idea. Has anyone else experienced this challenge?

The P0016 and P0017 codes indicate issues with the camshaft and crankshaft sensor alignment in the Chevy Equinox. This can lead to poor engine performance and even stalling. It’s crucial to get them checked as soon as possible.

Thanks for the clear explanation! I had no idea they could impact performance so drastically. What other symptoms should I look for?

Common symptoms include rough idling, difficulty starting, and decreased acceleration. You’ll also notice a drop in fuel efficiency, which is frustrating!

Exactly! I experienced some of those symptoms before getting the codes read. It was a hassle. Has anyone else had a similar experience?

Yes, I had similar issues last year. The car would jerk during acceleration. Turned out to be a faulty camshaft sensor. It was a pain to fix, but worth it in the end!

I read that sometimes this can be caused by oil flow issues. If the VVT (Variable Valve Timing) solenoids are clogged, it might lead to these codes too. Has anyone looked into that?

That’s an excellent point! Maintenance like regular oil changes could prevent this. I wonder how neglected maintenance contributes to these codes?

I think a lot of drivers neglect the regular oil changes. This, combined with sensor wear, can definitely set off those codes. It’s a wake-up call!

Totally agree! My friend had his Equinox go into limp mode because of this. It was quite the scare!

Limp mode?! That’s a nightmare. I hope this thread helps people avoid similar problems. Any DIY solutions for the codes before heading to the shop?

You could try cleaning the sensors if they’re accessible. Resetting the codes after cleaning can sometimes help too. Just keep in mind it might be temporary!

Temporary fixes are better than no fixes! Any experience with folks who tackled this and it worked?

I tackled it myself and cleaning the sensors worked for a few weeks! Then the codes returned, so I ended up replacing the sensors. At least I saved on labor!

I had the P0016 and P0017 codes pop up last year. It turned out to be a faulty VVT sensor. After replacing it, the codes cleared and I’ve had no issues since!

That’s great to hear! I replaced my camshaft position actuator and it did the trick. It was a DIY job, and I saved a ton on labor!

I’ve been having these codes too. My mechanic mentioned it could also be a problem with the timing chain. Anyone else experienced that?

Yes! I had the same issue. They found my timing chain was off by a few teeth. After realigning it, the codes disappeared!

It’s amazing how these codes can lead to such different issues. I’ve been told it might even be a wiring problem. Has anyone checked their wiring?

I wish I had the luxury of checking wiring! I just took mine to a garage. They found several connectors corroded and replaced them.
