This summary uses the existing diagnostic information shown in full below.
This code means that the computer in your car has detected a problem with the fuel injector for cylinder 2. It's like a squirt gun that's supposed to spray fuel into the engine, but something is wrong with its power supply.
The P3152 code indicates an electrical issue in the high-pressure injector circuit for cylinder 2, specifically that the voltage is lower than expected.
The P3152 code is triggered when the Engine Control Module (ECM) detects a low voltage condition in the high side of the high-pressure injector circuit for cylinder 2. This can affect the injector's ability to deliver the correct amount of fuel, impacting engine performance.
• Engine misfire
• Poor fuel economy
• Check Engine Light illuminated
• Faulty fuel injector
• Wiring issues in the injector circuit
• Failed Engine Control Module (ECM)
ECM: Engine Control Module, the computer that controls engine functions.
Fuel Injector: A device that sprays fuel into the engine's intake manifold or cylinders.
• Use an OBD-II scanner to confirm the code.
• Inspect wiring and connectors for damage or corrosion.
• Test the fuel injector for proper operation.
• Replace or repair damaged wiring or connectors.
• Replace the faulty fuel injector.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Camry
• Honda Accord
• Ford F-150
• Regularly inspect and maintain fuel injectors.
• Keep electrical connections clean and secure.
• Use quality fuel to prevent injector clogging.
Engine Performance
• Do not ignore the Check Engine Light.
• Seek professional diagnosis if unsure.
• Regular maintenance can prevent such issues.
Check your vehicle's warranty; some powertrain warranties may cover injector issues.
Injector circuit issues have been common as vehicles rely more on precise fuel delivery systems.
Moderate – Addressing this issue promptly can prevent further engine damage.
Driving with a misfiring engine can be unsafe and may cause further damage.
• Engine running
• Warm operating temperature
The fuel injector for cylinder 2 is located on the engine, typically near the intake manifold.
Q: Can I drive with a P3152 code?
A: It's not recommended to drive for long periods with this code active, as it can lead to engine damage.
Q: How do I reset the Check Engine Light after repair?
A: You can use an OBD-II scanner to clear the code, or the light may turn off after a few drive cycles if the issue is resolved.
