P0260 — Injection Pump Fuel Metering Control "B" High (Cam/Rotor/Injector)
Drivable short-term, but fix now to avoid damage.
What P0260 means
This code means the engine computer sees a high signal or high voltage on the 'B' fuel metering control circuit of the diesel injection pump. It typically points to an open circuit, a short to power, or a failing metering valve or pump electronics. Fixing it usually starts with inspecting the wiring and connectors, then testing the pump's control components if the circuit checks out.
Common symptoms
- Check engine light is on
- Hard starting or no-start condition
- Reduced power and poor throttle response
- Rough or surging engine operation
- Engine may enter reduced-power limp mode
Common causes
- Open circuit in the metering control wiring
- Short to power (battery voltage) in the circuit
- Faulty fuel metering control valve in the pump
- Corroded or damaged connector at the pump
- Injection pump electronics or driver failure
Typical repair cost
$250 – $1800
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0260 code?
You may manage short distances, but it's not wise to keep driving on it. A high metering signal can cause rough running, power loss, and even a no-start. Get it diagnosed soon, and if the engine is struggling or in limp mode, head to a shop right away.
How much does it cost to fix a P0260 code?
Wiring and connector repairs are often a few hundred dollars. If the fuel metering valve or injection pump must be replaced, the bill can reach roughly $800 to $1,800 with parts and labor. A diagnosis pinpoints the cause so you don't overspend.
Is a P0260 code serious?
Yes, it's a serious code since it affects fuel delivery from the injection pump. Left unaddressed, it can leave you stranded with a no-start. It's worth fixing promptly even if the car still moves.
What does the 'High' in P0260 mean?
It means the voltage on the metering control circuit is higher than expected, usually from an open wire or a short to power. That's different from P0259 ('Low'), which signals voltage that's too low. The reading helps the technician focus the wiring test.
