What P245E means
Which sensor is B depends on the maker. Ford's 2013 6.7 L Power Stroke has an exhaust pressure sensor ahead of the filter as A and a two-port differential sensor across it as B. Despite its circuit title, P245E is there an offset test during after-run, with the key off and the controller still awake: since no gas flows, the differential reading should be zero, and more than 1 kPa for one second sets the code. On Ford's 2024 gasoline particulate filters with digital SENT sensors, P245E is the general circuit fault, detected within 5 s, while lost communication with the same sensor is U0602. So a sensor that drifted, a hose still holding pressure or water inside the sensor can set it as easily as a wiring fault. Low and high signals have their own codes, P2460 and P2461, and erratic signals P2462.
P245E at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P245E
- Malfunction indicator lamp on
- Soot load estimate unreliable, regeneration timing affected
Common causes of P245E
- Most likelySensor B offset drifted or moisture inside the sensor
- PossiblePressure hose kinked or blocked so pressure is trapped
- PossibleWiring or connector fault on the sensor B circuit
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P245E means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 4 | Area: auxiliary emission controls (catalytic converter, EGR, EVAP). |
| 5E | The exact fault in that area. |
What to do next
- Note P245E 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 P245E
What does P245E mean?
P245E means "Particulate Filter Pressure Sensor B Circuit". Which sensor is B depends on the maker. It is a generic code, so it means the same on every make.
Is it safe to drive with P245E?
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 P245E fail an emissions test?
Yes, it can. P245E 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 P245E to fix?
Difficulty: medium. A typical repair takes 0.3 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P245E 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.
