P0016 Code: Anyone Else Dealing with Crankshaft and Camshaft Correlation Issues?

Technical Discussions
1

I’ve been having some trouble with my vehicle lately, specifically with the P0016 error code, which points to a crankshaft position and camshaft position correlation problem on Bank 1 Sensor A. I’m having a hard time understanding what this means for my engine and how serious it might be.

Symptoms

  • The engine sometimes runs rough.
  • I noticed a decrease in power.
  • Fuel efficiency seems to be impacted.

What I’ve Tried

  • I’ve checked the oil and it seems fine, but I may need to change it.
  • I inspected the timing chain/belt for any visible issues, but nothing looks out of place.
  • Also, cleared the error codes a couple of times, but they keep coming back.

Questions

  1. What steps should I take next for diagnosing this code? Should I focus on the camshaft sensor or the crankshaft position sensor first?
  2. Could this be an indication of timing chain/belt issues? What are the common reasons for this code?
  3. Any recommended fixes or things I should look out for?

Any advice or experiences with this error code would be really appreciated! Thanks in advance for your help!

The P0016 code indicates a mismatch between the crankshaft and camshaft positions, which can lead to timing issues. It’s essential to diagnose quickly to avoid significant engine damage.

Thanks for the info! I started getting this code, and my car has been stalling. Could this be related?

Definitely could be! A failing sensor or timing chain issue can cause stalling as well.

I faced a similar issue! It turned out my camshaft timing gear was worn out. Had to replace it, and the code cleared immediately after.

That’s interesting! How can I tell if my gear is worn out?

If you notice grinding noises or if your engine runs rough, that could be a sign. A mechanic can check the timing with a scan tool too.

I’ve always wondered about the longevity of these parts. Is this something that typically fails as cars age?

9

Honestly, yes! Many people report such issues after about 100k miles, especially with high-stress driving conditions.

10

Good to know! I’ve been driving my car hard for a while now; I should probably get it checked.

11

Don’t wait too long! Ignoring the P0016 code can lead to costly repairs down the line.

12

How much should a timing gear replacement typically cost? Just trying to prepare for the worst here!

13

Depending on your vehicle, it could range from $500 to over $2000, especially if you go for OEM parts. Ouch!

Yikes! I better start saving! Maybe I’ll just trade it in for a bicycle instead! :joy:

Haha, a bicycle is a solid plan! But if you decide to keep the car, make sure to get a mechanic you trust to do the repairs.

I just dealt with a P0016 code in my car. It turned out to be a timing issue. Make sure to check the timing chain and its alignment first.

17

Thanks for the tip! How did you figure out it was the timing chain? Any specific symptoms to look out for?

18

I experienced rough idling and poor acceleration before the code appeared. Also, I had a strange sound from the engine that I thought was nothing but ended up being a warning sign.

Another thing to consider is checking your camshaft and crankshaft position sensors. If they are faulty, they might trigger that P0016 code.

Good point! Are there any easy tests to perform on those sensors?
