This summary uses the existing diagnostic information shown in full below.
This code means the car's computer thinks the fuel injectors are not spraying fuel at the right time.
The engine control module (ECM) monitors the timing of fuel injection and sets this code when it detects a deviation from the expected timing.
P026B is triggered when the ECM detects that the fuel injection timing is not within the expected range. This could be due to a malfunctioning injector, timing issues, or sensor problems.
• Engine misfires
• Poor fuel economy
• Rough idling
• Faulty fuel injector
• Timing belt or chain issues
• Defective camshaft or crankshaft position sensor

Engine Performance
• Do not ignore the check engine light
• Consult a professional mechanic
• Avoid driving with severe symptoms
Check vehicle warranty for coverage on fuel system components.
This code has been associated with timing issues in several vehicle models since the introduction of advanced fuel injection systems.
Moderate – Addressing this issue soon can prevent further engine damage.
Driving with a malfunctioning fuel injection system can lead to increased emissions and may not comply with local regulations.
• Engine at operating temperature
• Vehicle in idle or low-load conditions
Fuel injectors are located on the engine, typically near the intake manifold.
Q: Can I drive with a P026B code?
A: It's not recommended to drive with this code as it can lead to engine damage.
Q: How do I clear a P026B code?
A: After repairs, use an OBD-II scanner to clear the code, but ensure the issue is resolved first.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.
