P0015 on a 2017 Honda Civic
Exhaust Cam Over-Retarded (Bank 1, VVT)
P0015 on a 2017 Honda Civic indicates exhaust cam over-retarded (bank 1, vvt). It usually stays drivable short-term but should be diagnosed promptly. The most common cause is stuck-closed exhaust-side vvt oil control valve (typically $100–$450). Confirm the root cause before replacing parts.
What does P0015 mean on a 2017 Honda Civic?
P0015 is set when the engine control module commands the Bank 1 exhaust camshaft ("B" camshaft) to advance and the actual cam position stays too retarded — the phaser will not move off its base position, or moves too slowly to follow the command. It is the exhaust-side mirror of P0012 and the opposite-direction counterpart of P0014. As with every variable valve timing code, the usual causes are hydraulic rather than electronic: the oil control valve, the oil feeding it, or the phaser itself.
The symptoms, causes, and diagnostic steps below describe P0015 itself, so they read the same on nearby Honda Civic model years. Powertrain and trim details vary year to year — confirm the specifics against your own vehicle before buying parts.
Is it safe to drive a 2017 Honda Civic with P0015?
In most cases a 2017 Honda Civic stays drivable for short trips with P0015 active, but diagnose and repair it promptly. This is a high-severity code — ignoring it can lead to further damage or a failed emissions test.
What are the symptoms of P0015 on a 2017 Honda Civic?
- Check Engine Light is illuminated
- Rough idle
- Loss of mid-range torque and sluggish acceleration
- Engine feels flat or unresponsive under load
- Reduced fuel economy
- Increased emissions at idle
- Possible cold-start rattle from the cam area
What causes P0015 on a 2017 Honda Civic?
| Cause | Likelihood | Estimated repair (USD) |
|---|---|---|
| Stuck-closed exhaust-side VVT oil control valve Cleaning the valve and its inlet screen resolves a large share of these before any part is bought. | Most common | $100–$450 |
| Low engine oil level or low oil pressure starving the phaser | Most common | $50–$200 |
| Sludged oil galleries restricting flow to the exhaust phaser | Common | $100–$600 |
| Failed exhaust cam phaser stuck at its base (retarded) position | Common | $600–$1,800 |
| Stretched timing chain preventing the phaser from reaching commanded position | Occasional | $800–$3,000 |
| Exhaust cam position sensor reporting an offset position | Occasional | $100–$400 |
| Wiring fault between the PCM and the exhaust-side oil control valve | Occasional | $80–$350 |
Cost ranges are editorial estimates for parts and labor at an independent U.S. shop — not quotes. What you actually pay moves with your region, the shop's hourly rate, which engine you have, and how much diagnostic time the job takes. Dealer service departments typically sit above these ranges.
How to diagnose this on a 2017 Honda Civic
-
Check oil level, condition, and viscosity first
The VVT system uses engine oil as its hydraulic working fluid, so oil is not a formality here — it is the most likely cause. Check level on level ground with the engine warm. Dark, sludgy, or burnt-smelling oil, or the wrong viscosity from a previous service, will stop a phaser moving. Change it with the correct OEM-spec oil and filter before diagnosing further.
Tools: Dipstick or level check procedure, Replacement oil and filter (if needed)
-
Measure oil pressure with a mechanical gauge
A scan tool reading a pressure sensor is not good enough when the sensor itself might be part of the problem. Tee a mechanical gauge into the sender port and confirm pressure at idle and at 2500 RPM against the manufacturer's specification. Low pressure means a tired pump or worn bearings, and that has to be fixed before any VVT part is worth replacing.
Tools: Mechanical oil pressure gauge
-
Remove and bench-test the exhaust-side oil control valve
Pull the exhaust-side OCV and inspect the inlet screen for sludge and metal. Clean the valve and check it moves freely. Energised with 12 V it should click and pass air; de-energised it should seal. A valve stuck closed cannot direct oil into the phaser, which is precisely the P0015 condition.
Tools: Socket set, Brake cleaner, 12 V test source, Compressed air
-
Command exhaust cam advance with a bidirectional scan tool
Watch commanded versus actual exhaust cam position while commanding advance. A healthy system tracks within a degree or two. No movement at all points at the phaser or a blocked oil feed; slow or lagging movement points at the oil control valve or marginal oil pressure.
Tools: Bidirectional scan tool with cam position PIDs
-
Check cam-crank correlation for chain stretch
If the OCV is good and oil pressure is in spec, look at whether the cam-crank offset drifts as RPM rises. Drift under load points at a stretched chain, which limits how far the phaser can effectively move. A cold-start rattle from the timing cover alongside P0015 strengthens that case considerably.
Tools: Scan tool with cam-crank correlation PIDs, Mechanic's stethoscope

Service Bulletin - Due to a new North America regulation which introduces a new refrigerant and oil requirement, the compressor shaft seal may leak. American Honda is extending the warranty on the A/C compressor shaft seal from the original 3 years to 10 years from the original date of purchase, with no mileage limitation. The new refrigerant and oil may cause swelling of the compressor shaft seal. The swelling may lead to abnormal wearing of the seal which may increase seal gaps around the compressor shaft allowing refrigerant to leak out.
NHTSA #11002711 - VISIBILITY/WIPER Jun 19, 2024
Service Bulletin - American Honda is extending the warranty on the A/C condenser to 10 years from the original date of purchase with unlimited miles. This warranty extension only covers vehicles that have a defective A/C condenser from the factory. The A/C condenser was not manufactured to specification. As a result, corrosion may develop in the form of tiny holes in the condenser tube walls that allow the refrigerant to leak out.

Engines in the 2017 Honda Civic
The 2017 Honda Civic was offered with the 1.5L 4-cylinder and 2.0L 4-cylinder engines. Which one you have changes where P0015 is most likely to originate, so confirm your engine before ordering parts.
Engine data: EPA fueleconomy.gov.
Where P0015 sits in the VVT code family
Four codes cover Bank 1’s two camshafts and the two directions each can fail in:
| Code | Camshaft | Failure direction |
|---|---|---|
| P0011 | Intake (“A”) | Over-advanced |
| P0012 | Intake (“A”) | Over-retarded |
| P0014 | Exhaust (“B”) | Over-advanced |
| P0015 | Exhaust (“B”) | Over-retarded |
P0015 and P0012 — the two over-retarded codes — are the more common pair in practice, because a phaser that loses oil pressure springs back toward its base position by design. “Stuck at base” is the default failure state.
Start with the oil, not with parts
Variable valve timing is a hydraulic system that happens to be electronically controlled. The phaser is rotated by pressurised engine oil routed through a solenoid valve. Everything that degrades oil — extended change intervals, the wrong viscosity, a slow leak dropping the level, a worn pump — degrades VVT response first, because the oil passages feeding a phaser are among the smallest in the engine.
On engines under 100,000 miles, an oil change with the correct spec oil and a clean of the oil control valve resolves a large share of these codes with no parts bought at all. That is worth doing before anything else, and it costs a fraction of a phaser.
Cleaning the oil control valve is usually free
Remove the exhaust-side OCV and look at its inlet screen. If it is packed with varnish and sludge, that restriction alone can starve the phaser. Brake cleaner, a soft brush, and a functional check with 12 V takes about half an hour and frequently ends the diagnosis. Replace the valve only if it will not move freely after cleaning, or fails the energised air-flow test.
Driving with P0015
The engine runs. It will feel flat in the mid-range, idle less smoothly than it should, and use more fuel. Short trips are fine. What is not fine is ignoring it for months when the underlying cause is low oil pressure — that same low pressure is starving bearings and the timing chain tensioner, and those failures are engine-rebuild territory rather than a solenoid. If oil pressure is confirmed low, treat it as urgent.
