P1200 Fault Code: Understanding The Description And Troubleshooting Steps
The P1200 fault code indicates a malfunction in the fuel pump relay or ECU circuit. The fuel pump speed is controlled at three different steps based on the engine’s condition. When the engine starts or under heavy loads with high engine speed, the ECM sends a high signal to the fuel pump ECU, causing the fuel pump to operate at high speed.
Under heavy loads with low engine speed, the ECM sends a mid signal, resulting in the fuel pump operating at medium speed. During idling or light loads, the ECM sends a low signal, causing the fuel pump to operate at low speed. If there is an issue with the fuel pump relay or ECU circuit, this fault code will be triggered.
FAQ
If you’re seeing the engine light on or the service engine soon warning light, the fault code P1200 could be the culprit. This code can be caused by a faulty fuel pump ECU, an open or shorted fuel pump ECU harness, a poor electrical connection in the fuel pump ECU circuit, a faulty fuel pump, or a faulty engine control module (ECM). To visually inspect these possible causes, check the related wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded connector pins.
If you notice that your engine light is ON or you see a Service Engine Soon Warning Light, it could be due to a faulty Fuel Pump ECU or a poor electrical connection in the Fuel Pump ECU circuit. This can happen if the Fuel Pump ECU is faulty, if the harness is open or shorted, if there is a poor electrical connection in the circuit, or if the Fuel Pump or Engine Control Module (ECM) is faulty. To fix this issue, you should check the possible causes mentioned above. Take a close look at the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins in the connectors.
To fix the p1200 fault code and ensure the wiring harness and connectors are in good condition, start by visually inspecting the related wiring harness and connectors.
