What P25E0 means
On engines with two cylinder banks, P25E0 is the bank 2 counterpart of P25DD: the intake camshaft actuator stays latched at its locking angle when the module wants it free to advance or retard. Because only one side is affected, the cam angles of the two banks no longer match, and the module may hold both sides in a fallback position. Ford's 2014 OBD-II code interpretation list for the Boss 302S V8 includes P25E0 among four lamp codes for a phaser stuck in its lock. A pin that fails to retract usually goes back to oil supply: too little pressure at that head, wrong viscosity, a clogged feed screen or a sticking control valve; less often the pin is jammed mechanically. CARB requires the OBD system to detect valve timing that cannot reach its target. Typical complaints are low power, rough idle and higher consumption.

Symptoms of P25E0
- Check engine lamp on
- Reduced power and rough idle
- Higher fuel consumption
Common causes of P25E0
- Most likelyInsufficient oil pressure at the bank 2 head, low level or clogged feed screen
- PossibleBank 2 intake oil control valve sticking
- Less likelyLock pin mechanically jammed in the phaser
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P25E0 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 5 | Area: vehicle speed, idle control and auxiliary inputs. |
| E0 | The exact fault in that area. |
What to do next
- Note P25E0 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 P25E0
What does P25E0 mean?
P25E0 means ""A" Camshaft Position - Stuck In Locked Position (Bank 2)". On engines with two cylinder banks, P25E0 is the bank 2 counterpart of P25DD: the intake camshaft actuator stays latched at its locking angle when the module wants it free to advance or retard. It is a generic code, so it means the same on every make.
Is it safe to drive with P25E0?
Drive gently and only to a workshop. With P25E0 the car can go into limp mode (reduced power) to protect itself.
Will P25E0 fail an emissions test?
Yes, it can. P25E0 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 P25E0 to fix?
Difficulty: hard. A typical repair takes 0.5 to 7 hours of work. This is a job for a workshop.
Will P25E0 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.
