This summary uses the existing diagnostic information shown in full below.
The car's computer is having trouble controlling a part that helps open and close the exhaust valves on one side of the engine.
The P0029 code indicates a problem with the exhaust valve control solenoid circuit on bank 2, which is affecting its range or performance.
The P0029 code is triggered when the Engine Control Module (ECM) detects a performance issue in the exhaust valve control solenoid circuit on bank 2. This solenoid is responsible for controlling the timing of the exhaust valves, and any malfunction can affect engine performance.
• Check Engine Light is on
• Reduced engine performance
• Poor fuel economy
• Faulty exhaust valve control solenoid
• Wiring issues in the solenoid circuit
• ECM malfunction
Solenoid: A device that converts electrical energy into mechanical movement.
ECM: Engine Control Module, the computer that controls engine functions.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections to the exhaust valve control solenoid.
• Test the solenoid for proper operation.
• Replace the faulty exhaust valve control solenoid.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Socket set

Moderate
• Chevrolet Silverado
• Ford F-150
• Toyota Camry
• Regular maintenance and inspection of engine components
• Timely replacement of faulty sensors
• Keeping the engine clean and free of debris
Engine Performance
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional mechanic.
• Avoid driving long distances until the issue is resolved.
Check with the vehicle manufacturer for warranty coverage on engine components.
This code has been associated with issues in vehicles with variable valve timing systems, particularly in models from the mid-2000s onward.
Moderate – While the vehicle may still be drivable, it is important to address this issue to avoid further engine damage.
Driving with a malfunctioning engine component can lead to increased emissions and may not comply with local environmental regulations.
• Engine at operating temperature
• Vehicle in park or neutral
The exhaust valve control solenoid for bank 2 is typically located on the cylinder head of the engine, opposite to bank 1.
Q: Can I drive with a P0029 code?
A: It is not recommended to drive for extended periods with this code as it can lead to further engine issues.
Q: How can I reset the P0029 code?
A: You can reset the code using an OBD-II scanner, but it's important to fix the underlying issue first.
