P0028
Intake Valve Control Solenoid Circuit Range (Bank 2)
Severity
medium
Worth booking. It costs fuel, emissions or comfort until it is fixed.
Can you drive it
Only if running normally
A short trip to a shop may be reasonable if the light is steady and the car runs normally. Stop safely for a flashing light, severe shaking, overheating, loss of power, or another urgent warning. The code alone cannot confirm safety.
Indicative cost (USD)
$120–$600

Intake VVT solenoid (bank 2) circuit performance fault.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then work the likely-causes list in the order shown.
That order is what a shop checks first for this code — wiring and connections before the component they run to, because a connector costs nothing to inspect and is a common answer.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.
Common symptoms
- Check engine light
- Rough idle on bank 2 cylinders
Likely causes
- Failed VVT solenoidMost common
- Wiring/connector
- Low oil pressure

Bank 2 EXHAUST camshaft position actuator (OCV) circuit fault. Electrical-only code, mirror of P0013 on bank 2 exhaust. Only applies to dual-VVT V6/V8 engines (Toyota Dual VVT-i, Ford 3V/4V Coyote and Triton, GM dual-VVT, most German V-engines).
Cheapest-first ladder
- Ohm the bank 2 exhaust OCV — 6.9-7.9 ohms most Asian, 10-15 ohms Ford.
- Verify battery voltage and PCM PWM signal at the connector.
- Pull OCV and clean the inlet screen — bank 2 exhaust OCV screens varnish faster than any other position because they run hottest and farthest from the oil pump.
- Wiggle-test harness near the rear of the engine — heat-shield chafe is common. Don't replace the bank 2 exhaust cam phaser on a P0028 — this is a circuit code, mechanical phaser is innocent.

- 2007-2016Toyota Camry/Sienna/Highlander 2GR-FE V6 — bank 2 (rear, firewall-side) exhaust OCV is the most varnish-prone OCV in the entire engine, clean screen first; TSB covers it.
- 2011-2016Ford F-150 5.0L Coyote — bank 2 exhaust OCV connector pin fretting from engine vibration plus heat, repin terminals.
- 2008-2013GM 3.6L LLT/LFX (CTS, Traverse, Acadia, Enclave) — bank 2 exhaust OCV harness chafe against the firewall and intake bracket, inspect routing.
- 2007-2013Nissan VQ37VHR (370Z, G37) — bank 2 exhaust OCV failure at 70-100k, replace solenoid.

P0028 — frequently asked
What does a P0028 code mean?
Intake VVT solenoid (bank 2) circuit performance fault.
What causes a P0028 code?
Common causes: Failed VVT solenoid; Wiring/connector; Low oil pressure.
What are the symptoms of a P0028 code?
Typical symptoms: Check engine light; Rough idle on bank 2 cylinders.
Is it safe to drive with a P0028 code?
Only if running normally. A short trip to a shop may be reasonable if the light is steady and the car runs normally. Stop safely for a flashing light, severe shaking, overheating, loss of power, or another urgent warning. The code alone cannot confirm safety. Estimated repair: $120-$600.
How do I diagnose a P0028 code?
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed. 1. Note every code that is set, not just this one. 2. Read the freeze frame — the conditions the fault was recorded under. 3. Confirm the fault is current rather than history. 4. Then work the likely-causes list in the order shown.
