Monitor Description

Automatic Transaxle Models: 

• The ECM assumes that the vehicle is being driven when the vehicle speed sensor signal is being transmitted by the combination meter. If there is no signal from the combination meter despite the ECM detecting the speed signal from the speed sensor, the ECM interprets this as a malfunction in the speed signal circuit. The ECM then illuminates the MIL and stores the DTC.

Manual Transaxle Models: 

• The ECM assumes that the vehicle is being driven when the idle fuel-cut operation* is being executed. If there is no signal from the vehicle speed sensor despite this condition being met, the ECM interprets this as a malfunction in the speed signal circuit. The ECM then illuminates the MIL and stores the DTC.

  *: Idle fuel-cut is executed when the throttle valve is fully closed and engine speed is over 2800 RPM.
