What is the P0029 fault number? What is the Exhaust Valve Control Solenoid Range/Performance Bank 2 failure description? How do I fix the P0029 fault code What are the causes and symptoms of the P0029 error code?
What is the P0029 Fault code? What does it stand for?
Vehicles equipped with variable timing (VVT) will have a P0029 code triggered when the powertrain controller module (PCM), determines that the exhaust vales are slow to activate or not engaging at all. “Bank 2”, in the code description, indicates that there is an issue with the engine bank. The exhaust valve solenoid is located usually on the exhaust side of the Cylinder Head.
Note: This code can also be used in conjunction with codes P0078 , P0079 Or P0080 . These control solenoid-related fault codes should be removed before the P0029 fault code can be used.
The P0029 fault code can affect vehicles of all makes and models, including but not limited to Toyota, Volkswagen, Ford or Dodge.
What is the P0029 Fault Code?
Here are some reasons why P0029 should be set.
- – Exhaust valve control solenoid circuit open or closed
- – The exhaust valve solenoid circuit is prone to damage or rusty wires
- – A poor connection between ground cable and PCM
- – Low engine oil
- – Oil with an insufficient viscosity.
- – Obstructed oil passage lines
- – Solenoid for defective VVT oil control
- – Defective VVT actuator
- – Timing chain/timing belt misaligned or loose
What are the symptoms of the P0029 Fault Code?
These symptoms may be present if you own a vehicle that has the P0029 code.
- – Illumination for the check engine light
- – Lower engine performance
- – Engine hesitation during acceleration
- – Unusual operation of the engine
- Engine misfire
- – Higher fuel consumption
How to Fix the P0029 Fault Code
There are several repairs that can resolve the P0029 fault code.
- To determine if the fault will be back, it is important to first clear the codes.
- – Check your engine oil level. If it is low, you should replace it.
- – Oil filter and engine oil with a low viscosity must be replaced.
- – If your exhaust valve solenoid is not working properly, you should have it tested and replaced.
- – Repair of broken wires, connectors, or open or brief circuits to the exhaust control solenoid
- – Replacing damaged or loose timing chains or timing belts
- – Reparing or replacing the PCM connector
