Ever gotten a P0010 Chevy Malibu error and wondered what it meant? Well, you are not alone as many Malibu owners have wondered that exact same thing.
In this post, we are going to be looking at this in the error message and what it means when you get one. Chevy is one of the more popular Chevy brands available today.
Due to that and other factors, you will find that a lot of people will have faced this problem at one point or another. So, what exactly causes this error code to appear?
In short, The P0010 error code appears when the Powertrain Control Module (PCM) picks up a faulty solenoid. It is linked to the Engine Control Module and points to a mistiming issue between the bank 1 camshaft crankshaft.
What Causes P0010 Errors on the Chevy Malibu?
The following are some of the primary causes for a p0010 error:
- Oil sludge from lack of regular oil changes
- Engine timing issues
- Worn out guides, chains, and gears in the timing mechanism
- Sensor malfunctions in camshaft and crankshaft
- Expired ECM software
- Damaged wiring
- ECM damage
The presentation of these issues on the vehicles often comes in the exhibitions of certain things on the vehicle such as the “Check engine” light turning on.
Which is an immediate indication that you might need to take your car in for service. With a p0010 error code, the idle quality of the vehicle changes meaning it can have a rough idle and maybe as a result the combustion of the fuel might not be that efficient.
It is worth taking note that this is not the cause of the error but a symptom of it. Incomplete combustion of the fuel can greatly reduce the fuel efficiency of the car, giving it poor fuel economy. Meaning for a similar distance consumes more fuel than a car working properly.
As a consequence of the improper burning of the fuel the vehicle more often than not tends to fail an emission test because of the high amounts of carbon monoxide. And as stated before the performance of the car at higher RPMs is also greatly affected.
Diagnosing the P0010 Error Code
When diagnosing this error it is important to remember to clean the timing actuator first and see if that was the main issue or check the electrical circuit.
To properly diagnose a p0010 you would need an advanced scan tool capable of factory sensor readings and codes. In the hands of a qualified technician, he can interpret the data from the scan tool to decide when and where the problem is or whether it is still there.
They can even erase the code from the ECM and test drive the car while checking with the scan tool data to make sure the fault does not return. As engine sludge is a common problem related to this error code.
The solenoid indicated by the code should be removed and the screen filter inspected for sludge and manually activated with a test probe. For an intermittent fault, it is best to visually inspect the solenoid or the wiring. Otherwise, one would have to drive the vehicle until the problem becomes more persistent.
Using a digital voltage scope to observe the sensor signals is necessary when the error returns quickly. T. Generally, though, the scan tool should provide enough information from professional resources to be able to narrow down the problem.
How to Fix P0010 Error Code on Your Chevy Malibu
The following are ways to fix some of the issues:
- Inspect your wires and all the other things listed above visually.
- Use a digital voltage scope to analyze the wiring and signals from the solenoid to trace the problem.
- Assess whether Verify the timing marks on the crank and camshaft sprockets align.
- Look for signs of wear on the guide and timing belt or chain.
- Replace any faulty components
