What P245F means
With P245F the controller decides that the sensor B value is electrically fine but makes no physical sense. Ford's 2024 gasoline strategy runs three such tests on the B sensor of the gasoline particulate filter: an offset check with the engine stopped that fails once the average reaches 16 to 32 hPa; a rationality check that fails when the reading stays at or above the pressure expected for the current exhaust flow for a total of 20 s; and a derivative check that compares how fast pressure follows a change in flow over 2 s. Jeep released PCM software for 2018 Wranglers with a gasoline filter in Asia-Pacific and EMEA markets that set P245F together with P2453. Deutz assigns P245F to the pressure after the filter leaving its physical limits. Hoses, condensate and sensor drift are the usual suspects. Circuit codes are P245E, P2460 and P2461.
P245F at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P245F
- Malfunction indicator lamp on
- Filter regeneration triggered too early, too late or blocked
Common causes of P245F
- Most likelySensor B hose cracked, disconnected or blocked
- PossibleCondensate in the pressure line falsifying the reading
- PossibleSensor B drifted out of calibration
- Less likelyControl software needing an update (some Jeep models)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P245F 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). |
| 5F | The exact fault in that area. |
What to do next
- Note P245F 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 P245F
What does P245F mean?
P245F means "Particulate Filter Pressure Sensor B Circuit Range/Performance". With P245F the controller decides that the sensor B value is electrically fine but makes no physical sense. It is a generic code, so it means the same on every make.
Is it safe to drive with P245F?
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 P245F fail an emissions test?
Yes, it can. P245F 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 P245F to fix?
Difficulty: easy. 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 P245F 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.
