P2359 means the pressure trace of cylinder 10 changes too little: the build-up through compression and combustion is flatter than the ECM expects. No manufacturer documents this code for cylinder 10. Saab's 9-5 diesel lists the cylinder-1 analogue P039C with three sub-types, 00, 01 and 02, and counts it as a signal performance fault that reacts after 0.2 s out of range; what separates the sub-types is not explained there. BorgWarner's sensor glow plug passes the pressure through a flexible heater rod onto a measuring diaphragm, so a rod jammed by carbon or a stiff diaphragm flattens the curve. A cylinder with hardly any compression looks the same. In a V10 firing 1-6-5-10-2-7-3-8-4-9, as Ford's 6.8 L and Audi's 5.2 do, cylinder 10 is the fourth to fire.
Medium severity. Can I keep driving?If the car is running normally, drive in moderation to a repair shop. If it loses power or another warning appears, do not continue.
Cylinder 10 is numbered according to the manufacturer: check your engine's manual before working on it.
Symptoms
- Check engine light on
- Engine behaviour usually unchanged
Most likely causes
- Heater rod stuck in carbon, pressure no longer reaches the diaphragm
- Sensing element has lost sensitivity
- Cylinder 10 builds up hardly any pressure
What to check, in order
Start with the simplest. You can tick off each step.
