Note:
The engine speed (RPM) sensor detects RPM

started without a signal from the engine speed
(RPM) sensor -G28-. If the engine speed (RPM)
sensor -G28- signal fails while the engine is
running, the engine will stop immediately.

Test sequence

- Before performing test, check sensor for proper
installation and proper fitting.

- Disconnect harness connector for the engine
speed (RPM) sensor (identification: gray
harness connector).

Note:
Resistance value of the engine speed (RPM) sensor is based on a
temperature of 20 C. Resistance increases as temperature increases. - Connect multimeter between terminal 2 and 3 for resistance
measurement.
