Cylinder 10 High Pressure Injector Low Side Circuit Low
This code means there's a problem with the part of the car that sprays fuel into the engine for cylinder 10. It's not working right because the electrical signal is too low.
The engine control module (ECM) has detected that the electrical circuit for the high-pressure fuel injector on cylinder 10 is showing a low voltage condition.
The P3137 code indicates a malfunction in the low side circuit of the high-pressure fuel injector for cylinder 10. This can be due to a low voltage signal detected by the ECM, which may result from wiring issues, a faulty injector, or problems within the ECM itself.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections for cylinder 10's injector.
• Test the injector's resistance and functionality.
• Repair or replace damaged wiring or connectors.
• Replace the faulty injector.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Injector tester

Engine Performance
• Have your vehicle inspected by a professional.
• Do not ignore the Check Engine Light.
• Regularly maintain your vehicle to prevent such issues.
Check with your vehicle manufacturer for specific warranty coverage related to the fuel injector and ECM.
This code has been associated with vehicles equipped with direct fuel injection systems, where injector issues can arise due to complex electronics.
Moderate – While the vehicle may still be drivable, reduced performance and potential engine damage can occur if not addressed.
Driving with a misfiring engine can lead to increased emissions and potential safety hazards. Address the issue promptly.
• Engine running
• Vehicle at operating temperature
The fuel injector for cylinder 10 is located on the engine block, typically under the intake manifold.
Q: Can I drive with a P3137 code?
A: It's not recommended to drive for long periods with this code as it can lead to engine damage.
Q: How can I prevent injector issues?
A: Regular maintenance and using high-quality fuel can help prevent injector problems.
