P2010 trouble code definition
P2010 is a generic OBD2 trouble code that indicates a fault within the intake manifold runner control circuit.
This code is similar to P2005, P2006, P2007, P2008, P2009, P2013 and P2015.
What the P2010 code means
P2010 means that the control circuit for bank intake manifold runner has a voltage that is out of normal and on the high end. The ECU tries to control the intake manifold runner but it detects the high voltage and triggers a Check Engine Light.
This Check Engine Light is illuminated on the dashboard and may be accompanied by a failsafe mode. This failsafe mode is to prevent damage to the vehicle and will remain active until the code is cleared or the voltage drops back into a normal range.
What causes the P2010 code?
- Poor electrical connections
- Intake air runner bound of stuck in place
- Failed intake manifold control solenoid
- Wiring harness that has an open or short
What are the symptoms of the P2010 code?
Drivers may notice no symptoms at all except for the Check Engine Light.
You may also experience a lack of low end power and the engine running roughly.
How does a mechanic diagnose the P2010 code?
Install the scan tool into the vehicle's DLC port and check for any present, history, or pending codes.
Take note of the freeze frame data associated with every stored code.
Clear all the codes and freeze frame data.
The vehicle will now be taken on a test drive with care to recreate the circumstances from the freeze frame data.
Next, a visual inspection will be performed, looking for any frayed or damaged wiring, broken vacuum lines, and components that are visibly damaged.
Lastly, a scan tool will be used to monitor the intake manifold control solenoid operation and voltage.
Common mistakes when diagnosing the P2010 code
Even the best technicians can make mistakes when diagnosing codes if they do not follow the diagnostic process and complete all steps in the proper order and in their entirety. When steps are skipped or not done simple items can be overlooked in favor of larger ones.
How serious is the P2010 code?
If the intake manifold runner flap door breaks it can cause serious engine damage. This generally happens when the Check Engine Light is neglected for long periods of time. In general P2010 causes minor symptoms if it is taken care of promptly.
What repairs can fix the P2010 code?
- Replacement of the intake manifold runner control solenoid
- Fixing the poor electrical connection
- Unblocking the intake manifold runner doors
- Repair or replacement of the wiring harness
Additional comments for consideration regarding the P2010 code
An advanced level scan tool will be required to diagnose the P2010 code. These tools allow technicians to quickly determine if a sensor or solenoid is working properly but checking the live data stream.
Vehicles with binding or blocked intake manifold runner doors can be repaired by using a solvent that is applied through the intake. This breaks up carbon deposit.
