What P0075 means
A solenoid valve on the cylinder head controls oil flow for the variable valve control on the intake side of bank 1. Depending on the manufacturer it drives a camshaft phaser (for example on Nissan engines) or a valve lift changeover (for example on Subaru engines). This code family reports electrical faults in its control circuit; P0075 is the general circuit fault: open circuit or short, without distinguishing between them. Some manufacturers use only this code for all electrical faults of the valve. Other manufacturers report the same valve under the "camshaft position actuator" codes instead. Valve control is then switched off or stays in its base position.
P0075 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 1.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P0075
- Check engine light on
- Less power, especially at high engine speed with lift changeover
- Rough idle possible
- Follow-up codes for camshaft timing or misfire possible
Common causes of P0075
- Most likelySolenoid coil open or shorted
- Most likelyWiring or connector interrupted, chafed or corroded
- PossibleOil at the connector, e.g. from a leaking valve O-ring
- Less likelyOutput driver or supply in the engine control module faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0075 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 0 | Area: fuel and air metering and auxiliary emission controls. |
| 75 | The exact fault in that area. |
What to do next
- Note P0075 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0075
What does P0075 mean?
P0075 means "Intake Valve Control Solenoid Circuit Bank 1". A solenoid valve on the cylinder head controls oil flow for the variable valve control on the intake side of bank 1. It is a generic code, so it means the same on every make.
Is it safe to drive with P0075?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P0075 fail an emissions test?
Yes, it can. P0075 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0075 to fix?
Difficulty: medium. A typical repair takes 0.5 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0075 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
