P1200 Fuel Pump Relay/Ecu Circuit at Charlie Shepherd blog

P1200 Fuel Pump Relay/Ecu Circuit. Test the fuel pump relay and ecu for proper functioning using a multimeter or suitable testing equipment. Test the fuel pump relay and ecu. The p1200 code refers to a malfunction in the fuel pump relay circuit. The fault code p1200 can be caused by the following: When the idling or light loads, the ecm sends a low signal (about 1.3 v) to the fuel pump ecu (fpc terminal). The fuel pump speed is controlled at two levels (high speed or low speed) by the condition of the engine (starting, light load, heavy load). This malfunction can cause the fuel pump to stop. How to fix a toyota p1200 code, fuel pump relay/ecu circuit malfunction.possible. 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, and a faulty engine control module (ecm). Inspect the fuel pump relay and ecu circuit for any visible damage, corrosion, or loose connections. In the diagram below, when the engine is cranked, current flows from terminal st of the ignition switch to the starter.
