Camry Sedan 4-Door L4-132 2164cc 2.2L DOHC (5S-FE) (1995)
Circuit Opening Relay: Description and Operation
PURPOSE
The Circuit Opening Relay provides power to the fuel pump.
OPERATION
The relay consists of a single set of contacts controlled by two separate coils. One coil is energized when the key is turned to the start position and
the fuel pump is supplied power during cranking. Once the Engine Control Module receives a signal from the NE coil (engine rpm sensor), it
grounds the other coil which continues to hold the contacts closed after the key is released to the run position.
