P0260 Injection Pump Fuel Metering Control B Intermittent (Cam/Rotor/Injector)
Check engine lightOn
EmissionsRelevant
Drive cycleRequired
Limp modePossible
P0260 reports brief dropouts or jumps in the circuit of fuel metering actuator B on a diesel injection pump that do not last long enough for the low or high code (P0258/P0259) – typically a loose contact or a wire breaking under vibration. No manufacturer using P0260 was found; the description follows CARB's continuous circuit monitoring requirement and Saab's diagnosis of the same two-valve pump, which recommends a wiggle test with the valves activated.
Likely causes
Loose contact or corrosion at the metering valve B connector
Broken or chafed wire in the harness to the pump (vibration, heat)
Metering valve B with internal dropouts
Unstable supply or ground
Symptoms
- Check engine light on
- Occasional jerking or brief loss of power
- Limp mode possible
