What P2895 means
P2895 is set when cylinder 2 delivers an ion signal that is electrically intact but does not behave plausibly – for example, it shows almost no combustion peak at normal load, or it scatters strongly from cycle to cycle compared with the neighbouring cylinders. Because the ion current is a direct image of combustion, a genuine problem in cylinder 2 such as a lean injector, a leaking valve or low compression can trigger this code just as well as a dirty plug. That makes it worth reading misfire counters and fuel trims before replacing parts. Saab processes the raw signal with filters that separate the slow combustion part from the fast knock ringing. No manufacturer describes P2895 publicly; electrical faults on cylinder 2 belong to P2894, P2896 and P2897.
P2895 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 2 hours
- Clears after repairAfter a drive cycle
Symptoms of P2895
- MIL, sometimes with misfire code P0302
- Uneven running felt mainly at idle
- Increased fuel consumption
Common causes of P2895
- Most likelyWorn or fouled spark plug in cylinder 2
- PossibleCombustion fault in cylinder 2 (injector, valve, compression)
- PossibleCoil 2 measuring stage drifting with temperature
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2895 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 8 | Area: transmission. |
| 95 | The exact fault in that area. |
What to do next
- Note P2895 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 P2895
What does P2895 mean?
P2895 means "Cylinder 2 Ion Current Sense Circuit Range/Performance". P2895 is set when cylinder 2 delivers an ion signal that is electrically intact but does not behave plausibly – for example, it shows almost no combustion peak at normal load, or it scatters strongly from cycle to cycle compared with the neighbouring cylinders. It is a generic code, so it means the same on every make.
Is it safe to drive with P2895?
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 P2895 fail an emissions test?
Yes, it can. P2895 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 P2895 to fix?
Difficulty: easy. A typical repair takes 0.3 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2895 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.
