What Does p3497 Chevrolet Impala mean?

By Nick Marchenko, PhD

In simple terms, the p3497 diagnostic trouble code essentially indicates an issue with the cylinder deactivation system in Bank 2. You might be wondering, "What's this all about?" This means there's a problem with the engine Bank 2 of the cylinder deactivation system.

Maybe the engine oil is low or has become dirty. There could also be a chance of damaged wiring messing things up. Most of the time, like 90% of it, you'll notice a lit-up check engine light and your Chevrolet Impala might start guzzling fuel. It's always wise to address these issues pronto for your Impala to run at its best.

What Does p3497 Mean for the Chevrolet Impala? 

As we touched on before, the DTC p3497 pinpoints a snag in engine Bank 2 of the cylinder deactivation system. This cylinder deactivation, also known as variable displacement, is pretty nifty when it comes to saving fuel. When your Impala's engine doesn't need to go full throttle, this system steps in. But if something goes sideways in this system, the PCM will jot down the code p3497.

The PCM will jot down the code P3497 if it spots something off in the cylinder deactivation system or can't get the system to work right for engine bank 2.

Breakdown of the Code

Here's a closer look at the meaning of the code.

• "P" is all about the PowerTrain.
• 3497 zooms in on the cylinder deactivation system. 

What Could Cause this P3497 Code in a Chevrolet Impala?

Let's dive into the potential culprits for this p3497 code.

• First off, you might trigger the code if there's low engine oil level or pressure.
• Maybe you haven't peeked at your engine oil in a dog's age and it's dirty as all get-out. Dirty engine oil can set off the code.
• Then again, maybe the engine oil is doing its thing, but there's a hiccup in the circuits. You could be dealing with shoddy connections or wires gone rogue.
• Every so often, the troublemaker is a funky cylinder deactivation system sensor or a PCM glitch.
• Or heck, sometimes things just wear out and you're dealing with a mechanical issue.

How Do I Tackle the p3497 code for the Chevrolet Impala? 

Alright, let's dive into how you can tackle this code for your Impala.

Scope Out That Engine Oil Level

First off, if you want your Impala purring smoothly, double-check that the oil's hitting the mark. If not, that VCM system might just throw a fit. 

Give That Engine Oil a Once-Over

Also, don't forget to check that you're using the right oil for the job. If it's looking more like mud wrestling material than pristine liquid gold, it might be time for a change. Remember, gunky oil and your Impala? Not the best of friends.
