DTC P0500
Vehicle speed sensor (VSS) circuit malfunction
DETECTION
CONDITION
• Vehicle speed signal not input after following conditions are met and 4.5 seconds or more have passed
— D, L, or S range.
— Engine coolant temperature 60
°C {140 °F} or above.
— Turbine speed 1,500 rpm or above.
Diagnostic support note:
• This is a continuous monitor (CCM).
• MIL illuminates if PCM detects the above malfunction condition in two consecutive drive cycles or in one
drive cycle while the DTC for the same malfunction has been stored in the PCM.
• PENDING CODE is available if PCM detects the above malfunction condition during first drive cycle.
• FREEZE FRAME DATA is available.
• HOLD indicator light flashes.
• DTC is stored in the PCM memory.
POSSIBLE
CAUSE
• VSS malfunction
• Open circuit between VSS terminal B and PCM terminal 3C
• Short to ground between VSS terminal B and PCM terminal 3C
• Open circuit between VSS terminal A and fuse block connector (X-01) terminal AJ
• Open circuit between VSS terminal C and body ground
• Damaged connectors between VSS and PCM
• PCM malfunction

ON-BOARD DIAGNOSTIC
Diagnostic procedure
STEP
INSPECTION
ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN
RECORDED
• Has FREEZE FRAME PID DATA been
recorded?
Yes Go to next step.
No
Record FREEZE FRAME PID DATA on repair order, then
go to next step.
2
VERIFY RELATED SERVICE INFORMATION
AVAILABILITY
• Check for related Service Bulletins availability.
• Is any related repair Information available?
Yes Perform repair or diagnosis according to available repair
Information.
• If vehicle is not repaired, go to next step.
No
Go to next step.
3
INSPECT VSS CONNECTOR FOR POOR
CONNECTION
• Turn ignition key to OFF.
• Disconnect VSS connector.
• Check for poor connection (damaged/pulled-
out terminals, corrosion, etc.).
• Is connection okay?
Yes Go to next step.
No
Repair or replace pin or connector, then go to Step 10.
4
INSPECT VSS POWER CIRCUIT FOR OPEN
CIRCUIT
• Verify that VSS connector is disconnected.
• Turn ignition key to ON (Engine OFF).
• Check voltage between VSS terminal A
(harness-side) and ground
• Is voltage reading B+?
Yes Go to next step.
No
Repair or replace harness, then go to Step 10.
5
INSPECT VSS GROUND CIRCUIT FOR OPEN
• Turn ignition key to OFF.
• Verify that VSS connector is disconnected.
• Check for continuity between VSS terminal C
(harness-side) and ground
• Is there continuity?
Yes Go to next step.
No
Repair or replace harness, then go to Step 10.
