SENDER - A component that is used with a temperature or pressure gauge. The sender measures the temperature or pressure. Its resistance changes to give an indication to the gauge of the temperature or pressure. RELAY (Magnetic Switch) - A relay is an electrical component that is activated by electricity. It has a coil that makes an electromagnet when current flows through it. The electromagnet can open or close the switch part of the relay.
MAGNETIC LATCH SOLENOID - A magnetic latch solenoid is an electrical component that is activated by electricity and held latch by a permanent magnet. It has two coils (latch and unlatch) that make electromagnet when current flows through them. It also has an internal switch that places the latch coil circuit open at the time the coil latches.

Failure Mode Identifiers (FMI)¹
Failure Description Data valid but above normal operational range. Data valid but below normal operational range. Data erratic, intermittent, or incorrect. Voltage above normal or shorted high. Voltage below normal or shorted low. Current below normal or open circuit. Current above normal or grounded circuit. Mechanical system not responding properly. Abnormal frequency, pulse width, or period. Abnormal update. Abnormal rate of change. Failure mode not identifiable. Bad device or component. Out of calibration. Parameter failures. Parameter failures. Parameter not available. Module not responding. Sensor supply fault. Condition not met. Parameter failures.
Wire Gauge
SOLENOID - A solenoid is an electrical component that is activated by electricity. It has a coil that makes an electromagnet when current flows through it. The electromagnet can open or close a valve or move a piece of metal that can do work.

CIRCUIT BREAKER (C/B) - A component in an electrical circuit that will open the circuit if too much current flows through it. This does not destroy the circuit breaker and it can be reset to become part of the circuit again.
The connectors shown in this chart are for harness to harness connectors. Connectors that join a harness to a component are generally located at or near the component. See the Component Location Chart.
