Causes and Fixes P0014 Code Chevy Trailblazer

If you have a Chevy Trailblazer with a P0014 OBDII error code, there are several causes and fixes.

A P0014 Code means the onboard computer is seeing low oil pressure.

Below are the most common symptoms, along with causes and fixes.

What is a Chevy Trailblazer P0014 Code?

A P0014 error code is an “Exhaust (B) Camshaft Position System Performance.”

Some scan tools will give an Exhaust (B) Camshaft Position Timing – Over Advanced Bank 1.

The most common cause of a Chevy Trailblazer with a P0014 error code is low oil or bad actuator solenoid.

Other things can also cause problems, but these are by far the most common solution.

Chevy Trailblazer Code P0014 Symptoms

A P0014 can give varying symptoms but usually will run rough or stall when cold.

Also, the engine light and oil maintenance light will usually come on.

Causes and Fixes P0014 Chevy Trailblazer

The first thing to check is the oil level since a P0014 error code can be caused by little to no oil in the engine.

Often the dipstick will show no oil or very little, but it may be at a good level, so be sure to check it twice.

If the engine oil is low and adding oil solves the problem, it would be a good idea to have the oil changed.

Keep in mind when the engine is low on oil, damage may have been caused depending on how low it was.

A bad or dirty Variable Valve Timing (VVT) Solenoid is a common problem with the Chevy Trailblazer.

When it becomes dirty or plugged up, it causes problems, including the P0014 error code.

The unit has screens that get dirty and clogged, which will cause an issue.

The solenoid is located behind the power steering pump, which will need to be removed to get to it.

The Solenoid can be bought at an auto part store or online on Amazon or eBay.

Summary
A P0014 OBDII trouble code given by an OBDII code reader on a Chevy Trailblazer is usually caused by low oil or VVT solenoid.

This is often an easy fix, as long as other damage has not been caused, and the fix is usually to replace the solenoid.

If the oil level has dropped too low, the engine can become damaged and cause many issues.

If the oil level is good, the solenoid should be checked next and is a common failure.

The solenoid has small filter screens that can become clogged up, stopping the flow of oil.

Changing the oil is also usually a good idea as old oil can cause issues.

Some mechanics clean the solenoid and insert it back in, which I would not recommend since they are low-cost, and another component on the solenoid may have failed.

Chevy Trailblazer P0014: Causes + How to Fix

P0014 is a relatively common trouble code for vehicles that have Variable Valve Timing (VVT). This includes the Chevy Trailblazer.

VVT adjusts the position of the camshaft(s) to maximize the combustion efficiency of the motor. P0014 means that the camshaft position is too far advanced from where it should be in relation to normal operating specs.

Before doing anything, check your Trailblazer’s oil level. Low oil is the number one cause of P0014.

P0014 Quick Reference Table

P0014 Definition	“B” Camshaft Position Timing Over Advanced or System Performance (Bank 1)
Symptoms	Stalling, decreased MPG, rattling, engine running rough, check engine light
Common Causes	Low oil, wrong oil viscosity, faulty camshaft actuator, timing chain/belt jumped
Breakdown Risk	Not usually, but in rare cases, the underlying causes can damage the engine. Don’t drive with P0014.
Repair Cost (Parts Only)	Usually well under $200

Chevy Trailblazer: P0014 Definition

The technical definition of P0014 for the Trailblazer is “B” Camshaft Position Timing Over Advanced or System Performance (Bank 1). Here it is separated into its three main pieces, with a quick explanation of each.

“B” Camshaft Position

Engines equipped with VVT use camshaft actuators (they’re often called phasers) to adjust the position of the cam. Adjusting the camshaft timing allows an engine to have a better power curve and better fuel economy (the automotive equivalent of having your cake and eating it too).

Depending on the vehicle, the “B” camshaft is the exhaust, right or rear camshaft.

Over Advanced or System Performance

VVT allows an engine to act as though it has different camshaft profiles at different RPMs; this is great for both power and fuel economy. It can advance or retard the timing at will. Sometimes, the system will get stuck in an over-advanced position.

When this happens, your Chevy Trailblazer will store trouble code P0014.

Valve timing control methods can be quite different for every engine, even from the same manufacturer, but the basics are the same.

Camshaft actuators or phasers change how long the intake and exhaust valves stay open. They are hydraulic, which means that they use the vehicle’s engine oil to change the intake valve timing.

Some simpler systems change the cam timing, while others change cam profiles entirely. Here’s a detailed write-up on exactly how VVT works if you’re interested in learning more.

Bank 1

Bank one is the side of the engine with the first cylinder. If your Trailblazer has an inline engine, you don’t need to concern yourself with this.

But, if your Trailblazer has a “V” engine, it’ll have two cylinder heads. You’ll need to look up which side is bank 1. It’s usually the cylinder head closer to the front of the engine.

Symptoms of P0014

When the cam timing is off, it can cause some issues with the motor. Here are some of the typical symptoms of P0014 in the Chevy Trailblazer:

• Poor Idle Quality– If the “B” camshaft actuator fails while it is too far advanced, it’ll idle roughly.
• Rattling Sound– You may hear the camshaft actuator rattling at idle speed since it’s not where it’s supposed to be. A rattling sound can also indicate the timing chain jumped a tooth.
• Decreased Gas Mileage– Now that your Trailblazer’s engine can no longer adjust its cam timing on the fly, it will no longer be able to produce optimum combustion, which causes poor economy.
• Lost Power– Your truck’s engine will not be able to produce as much power; this is because the cam profile will not allow it to run a performance power curve when you need more power.
• Service Engine Soon Light– Most of the time, you’ll be able to feel or see one of the above symptoms, but if you can’t, the check engine light will come on and let you know something is wrong.
• Hard to Start– With the timing too far advanced, it won’t be easy to start the motor, especially when it is warm.

Chevy Trailblazer P0014: Causes + How to Fix

Here are the most common causes of the P0014 code in your Chevy Trailblazer. Start by checking your vehicle’s oil level.

Here are the most common causes, presented in order from the easiest thing to check to the most difficult:

Engine Oil

The first thing you should do is check your Trailblazer’s oil. There are three ways that it can cause P0014:

• Low Oil: The most common cause of P0014 is low oil. The oil level needs to be low enough to lower the engine’s oil pressure (dangerously low). If oil flow slows down enough to throw the p0014 code, It’s likely low enough to lock up the engine.
• Dirty Oil: If the oil and/or oil filter haven’t been changed in a long time, sometimes it can cause the camshaft actuator to clog up with sludge.
• Wrong Viscocity (Too Thick or Too Thin): If you recently had an oil change and your Trailblazer now has this code, change the oil again, and verify that the shop used the right oil.

Bad Exhaust Camshaft Position Actuator or Actuator Solenoid

The actuator solenoid can go bad over time. You certainly don’t want to start here since, a lot of the time, it’ll be something else that causes the P0014 to appear. Here’s a good video that explains how to test the camshaft actuator using a scan tool:

Engine Timing

If your Trailblazer’s camshaft(s) are no longer synced to the crankshaft properly (such as if the timing chain jumped a tooth), it can cause the engine timing to be off enough to throw the P0014 (probably P0011, too), even though it’s not the actuator’s fault.

Wiring Issues

The wiring from the solenoid to the ECM can become damaged or broken, this will throw the P0014 OBDII code. The wiring harness to the intake camshaft position sensor may also develop a poor connection—YouTube: How to Find an Open or Short the Fast Easy Way.

Bad ECM (highly unlikely)

If your Trailblazer’s engine controller goes bad, it may throw this code along with other issues. Here’s how to tell if you have a bad ECM Autoblog: Symptoms of a Bad ECM.
