P2895Cylinder 2 Ion Current Sense Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
- What you may notice
- MIL, sometimes with misfire code P0302
- Uneven running felt mainly at idle
- Increased fuel consumption
- Likely causes
- LikelyWorn or fouled spark plug in cylinder 2
- PossibleCombustion fault in cylinder 2 (injector, valve, compression)
- PossibleCoil 2 measuring stage drifting with temperature
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.

- Easy · Often possible to do yourself.Typical cost: €30 – €500
