This summary uses the existing diagnostic information shown in full below.
The car's computer is saying that something is wrong with the part that helps put fuel into cylinder number 10. It's like a broken wire that stops electricity from getting to a toy, so the toy doesn't work.
This code indicates that the electrical circuit controlling the fuel injector for cylinder 10 is not working properly. It specifically refers to an open circuit, meaning there is a break or disconnection in the wiring.
The P3136 code is triggered when the Engine Control Module (ECM) detects an open circuit in the low side of the high-pressure injector for cylinder 10. This open circuit prevents the injector from receiving the necessary electrical signal to operate, which can lead to misfires or inefficient fuel delivery.
• Check Engine Light is on
• Engine misfires
• Poor fuel economy
• Damaged or corroded wiring to the injector
• Faulty injector
• Bad connection at the injector connector
Injector: A device that sprays fuel into the engine's cylinders.
ECM: Engine Control Module, the computer that controls engine functions.
• Inspect the wiring and connectors for damage or corrosion.
• Test the injector with a multimeter for continuity.
• Check the ECM for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the faulty injector.
• Reprogram or replace the ECM if necessary.
• Multimeter
• OBD-II Scanner
• Basic hand tools

Moderate
• Chevrolet Silverado
• GMC Sierra
• Ford F-150
• Regularly inspect and maintain wiring harnesses.
• Use quality fuel to prevent injector clogging.
• Perform regular engine tune-ups.
Engine Performance
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional mechanic.
Check with your vehicle manufacturer for warranty coverage on engine components.
This code has been associated with injector circuit issues in vehicles with high-mileage or those that have been exposed to harsh conditions.
Moderate – While the vehicle may still operate, it can lead to further engine damage if not addressed.
Driving with a misfiring engine can increase emissions and may not be compliant with local emissions regulations.
• Engine running
• Vehicle at operating temperature
The fuel injector for cylinder 10 is located on the engine block, typically near the intake manifold.
Q: Can I drive with a P3136 code?
A: It's not recommended to drive for extended periods with this code, as it can lead to further engine damage.
Q: How can I reset the Check Engine Light?
A: You can reset it with an OBD-II scanner, but it's important to fix the underlying issue first.
