Code No. P0500: Vehicle Speed Signal System
FUNCTION Receives the signal from the output shaft speed sensor used for the A/T control and converts it to the vehicle speed signal, and then inputs it to the engine control system and the speedometer.
TROUBLE JUDGMENT Check Conditions After 2 seconds pass from when the engine has completed the starting. The engine speed is 2, 500 - 4, 000 r/min. Under the high load operation. Judgment Criterion The sensor output voltage remains unchanged for 4 seconds. (The pulse signal is not input.) <Vehicles for Hong kong> The sensor output voltage remains unchanged (no pulse signal is inputted) for 2 second.
PROBABLE CAUSE Failed output shaft speed sensor Open/short circuit, in the output shaft speed sensor circuit or loose connector contact. Failed engine-A/T-ECU
| DIAGNOSIS PROCEDURE
| STEP 1. MUT-II/III other system diagnosis codes Confirm whether the diagnosis codes are output from A/T system. Q: Is the diagnosis code output for A/T system? YES: A/T system check (Refer to GROUP 23-Diagnosis Code Classified Table.) NO: Go to Step 2.
| STEP 2. MUT-II/III diagnosis code Reconfirmation of diagnosis code. Q: Is the diagnosis code set? YES: Replace engine-A/T-ECU. NO: Intermittent malfunction (Refer to GROUP 00- How to Use Troubleshooting/Inspection Service Points .)
