When your vehicle’s engine control module (PCM) detects an issue with cylinder performance, it may trigger the P0290 OBD-II trouble code. This code specifically refers to a problem with the contribution or balance of cylinder 10, indicating that one or more cylinders are not performing optimally.
What Does the P0290 Code Mean?
The P0290 code signifies that the PCM has detected a reduced contribution from cylinder 10. This means that the cylinder is not firing as it should, leading to decreased engine performance and efficiency.
What Causes the P0290 Code?
Several factors can trigger the P0290 code, including:
- Fuel injector failure
- Internal engine failure
- Powertrain Control Module (PCM) software needing an update
- Wiring issues related to the cylinder
What Are the Symptoms of the P0290 Code?
Symptoms associated with the P0290 code often include:
- Decreased engine performance
- Increased fuel consumption
How Serious Is the P0290 Code?
