P0029
Fix within a few daysThe engine computer detects a problem with the exhaust camshaft control system on Bank 2. This means the engine isn't able to adjust the exhaust valve timing on that side of the engine as it should.
Code P0029 means the exhaust camshaft control on Bank 2 has a performance issue. Common causes: Faulty VVT solenoid (70%), low/dirty oil (15%). Drivability: Yes, for short trips only. Repair cost: $50-$200 DIY, $150-$500 professional.
Can I Drive With P0029?
Yes, for short trips only
Essential trips under 10 miles, avoid highways and heavy acceleration. Fix within a few days.
Stop driving immediately if: Flashing Check Engine Light, loud engine noises, significant power loss, or burning smell.
Symptoms of P0029
- 1Reduced engine power
- 2Rough idle or stalling
- 3Decreased fuel economy
- 4Engine noise, such as ticking or rattling

Common Causes of P0029
Parts most likely causing this code, ranked by probability
The solenoid responsible for controlling the exhaust camshaft timing on Bank 2 is faulty, either electrically or mechanically stuck.
70% of P0029 cases are fixed by replacing this part
Variable valve timing systems rely on clean engine oil at the correct level and viscosity to operate properly; sludge or low oil pressure prevents the solenoid from functioning.
15% of P0029 cases are fixed by addressing oil condition
Damaged wires, corroded terminals, or a loose connection to the exhaust VVT solenoid on Bank 2 prevent proper electrical control.
10% of P0029 cases are fixed by repairing wiring
A faulty camshaft position sensor on Bank 2 can send incorrect signals to the engine computer, leading it to believe the VVT solenoid is not performing correctly.
5% of P0029 cases are fixed by replacing this sensor
Check These First (Before Buying Parts)
- Verify engine oil level and condition. Low or dirty oil is a common cause.
- Inspect the electrical connector and wiring to the exhaust VVT solenoid on Bank 2 for any visible damage, corrosion, or looseness.
How to Diagnose P0029
- 1Check engine oil level and condition; ensure it is full and clean.
- 2Inspect the electrical connector and wiring to the exhaust VVT solenoid on Bank 2 for damage or corrosion.
- 3Test the resistance of the exhaust VVT solenoid on Bank 2 using a multimeter; compare to specifications or swap with Bank 1 solenoid if accessible to see if the code moves.
- 4Remove and visually inspect the exhaust VVT solenoid on Bank 2 for debris or sludge blocking the screen.
- 5Use a scan tool to monitor live data for camshaft position and VVT solenoid command/actual values.
P0029 on Popular Vehicles
Ford F-150
2004-2014Ford's 5.4L 3V Triton engines are notorious for VCT solenoid issues, often accompanied by ticking noises and rough idle. Oil pressure and sludge are critical factors.
80% fixed by replacing VCT solenoids and ensuring proper oil
Toyota Camry
2007-2024Toyota V6 engines (e.g., 2GR-FE) can experience P0029 due to VVT solenoid failure, sometimes exacerbated by infrequent oil changes leading to sludge buildup.
75% fixed by replacing VVT solenoid and oil change
Honda Accord
2003-2024Honda V6 engines (J-series) can trigger P0029 if the VTEC oil pressure switch or the VTEC solenoid itself malfunctions. Always check for proper oil level and condition.
70% fixed by replacing VTEC solenoid or pressure switch
Frequently Asked Questions
What does P0029 mean?
P0029 indicates that your engine's computer has detected a problem with the exhaust camshaft control system on Bank 2. This system is responsible for adjusting valve timing to optimize engine performance and fuel economy.
Can I drive with P0029?
Yes, for short trips only. You can drive your vehicle with P0029, but expect reduced engine power, poor fuel economy, and a rough idle. Prolonged driving can lead to further engine damage or catalytic converter failure.
Will P0029 clear itself?
No, P0029 will not clear itself. This code indicates a persistent mechanical or electrical fault that requires diagnosis and repair. The Check Engine Light will remain on until the underlying issue is resolved.
How do I fix P0029 myself?
Start by checking your engine oil level and condition. If the oil is good, inspect the wiring and connector to the exhaust VVT solenoid on Bank 2. If those are fine, you will likely need to replace the exhaust VVT solenoid itself.
How much does it cost to fix P0029?
DIY repair costs for P0029 typically range from $50 to $200, primarily for a new VVT solenoid. Professional repair at a shop will cost between $150 and $500, including parts and labor.
P0029 keeps coming back - why?
If P0029 keeps returning, it often points to an underlying issue beyond just the solenoid. This could be due to persistent low oil pressure, clogged oil passages from sludge, a faulty camshaft position sensor, or a deeper internal engine problem affecting oil flow to the VVT system.
Will P0029 fail emissions/smog test?
Yes, P0029 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on is an automatic failure in most jurisdictions, and a malfunctioning VVT system directly impacts emissions.
What's the difference between P0029 and P0028?
P0029 refers to an issue with the **exhaust** camshaft control system on **Bank 2**. P0028 refers to an issue with the **intake** camshaft control system on **Bank 2**. They both indicate a problem on the same bank but affect different camshafts.
P0029 on Ford F-150?
On Ford F-150s, especially those with the 5.4L 3V Triton engine, P0029 is a common code related to Variable Cam Timing (VCT) solenoid failure. These solenoids can get clogged or fail electrically, leading to rough idle and ticking noises. Always check oil condition first.
Questions to Ask Your Mechanic
Did you check the engine oil level and condition before diagnosing the VVT solenoid?
Good answer: Yes, the first step was to confirm the oil was at the correct level and free of sludge. Low or dirty oil can directly cause VVT system malfunctions.
Did you test the electrical circuit to the VVT solenoid for proper voltage and resistance?
Good answer: Yes, we confirmed the wiring and connector were good, and the solenoid itself had the correct resistance, ruling out an electrical circuit issue before replacing the part.

Intermediate - Requires basic mechanical skills, locating the correct solenoid, and potentially using a multimeter for testing. Access to the solenoid can vary by vehicle.
Cost of Waiting
Ignoring P0029 can lead to significantly reduced fuel economy and engine performance. Continued driving with incorrect valve timing can cause excessive wear on engine components and, in severe cases, lead to internal engine damage or catalytic converter failure due to unburned fuel entering the exhaust. A $100 solenoid replacement now prevents a $1,000-$2,500 engine or converter repair later.
While You're In There...
VVT systems are highly dependent on clean, fresh engine oil. If you're diagnosing a VVT issue, a fresh oil change is a smart preventative measure and can sometimes resolve the issue if sludge was a factor.
If one VVT solenoid is failing due to age or oil contamination, others may not be far behind. Replacing them all at once can save future labor if they are easily accessible during the same repair.
Tools You'll Need
- Basic socket set
- Ratchet and extensions
- Screwdrivers
- Multimeter (for testing)
- Engine oil
- Oil filter (if changing oil)
- Scan tool (optional, but helpful for live data)
P0029 is a common engine code related to the variable valve timing system. Most repairs involve replacing a relatively inexpensive solenoid, and your engine will run much better afterward.

Your Next Steps
Step 1: Check your engine oil. Ensure it's at the correct level and clean. If it's low or dirty, perform an oil change.
Step 2: Locate the exhaust VVT solenoid on Bank 2. Inspect its electrical connector and wiring for any damage. If you have a multimeter, test the solenoid's resistance.
Step 3: If the oil and wiring are good, and the solenoid tests faulty, replace the exhaust VVT solenoid on Bank 2. You will likely need a new VVT solenoid.
