P2687: Your Engine’s Fuel System Is In Trouble
The P2687 code refers to the fuel heater relay control circuit. Ignition voltage is supplied to the coil side of the fuel heater relay when the ignition is On. The Engine Control Module (ECM) controls the fuel heater relay by providing a ground.
The voltage of the control circuit should be low when the ECM commands the fuel heater On. The voltage of the control circuit should be high when the ECM commands the fuel heater Off. The DTC will be set when the ECM detects an open fuel heater relay control circuit for more than 1 second.
FAQ
If you see the engine light on or service engine soon warning light, it could be due to the P2687 fault code. This code is usually caused by a faulty fuel heater relay, an open or shorted fuel heater relay harness, a poor electrical connection in the fuel heater relay circuit, or a faulty engine control module (ECM). To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
If you’re experiencing the P2687 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, there are a few things you can do to fix it. First, check the Possible Causes listed above, which include a faulty Fuel Heater Relay, an open or shorted Fuel Heater Relay harness, a poor electrical connection in the Fuel Heater Relay circuit, or a faulty Engine Control Module (ECM). To visually inspect the related wiring harness and connectors, look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
While a faulty Engine Control Module (ECM) is listed as a possible cause of the P2687 fault code, it is not a common cause. The most common cause is a faulty Fuel Heater Relay or issues with the related wiring harness and connectors. To fix the issue, it is recommended to visually inspect the wiring harness and connectors for any damage or corrosion and check for any broken or bent pins.
