DTC VEHICLE SPEED SENSOR MTR
Revision: June 20062007 Versa
DTC VEHICLE SPEED SENSOR MTRPFP:24814
DescriptionUCS005Q9
The vehicle speed sensor·MTR is built into the speedometer assembly. The sensor functions as an auxiliary
device to the revolution sensor when it is malfunctioning. The TCM will then use a signal sent from the vehicle
speed sensor·MTR.
CONSULT-II Reference ValueUCS005QA
Remarks: Specification data are reference values.
On Board Diagnosis LogicUCS005QB

This is not an OBD-II self-diagnostic item.

Diagnostic trouble code “VHCL SPEED SEN-MTR” with CONSULT-II or 2nd judgement flicker without
CONSULT-II is detected when TCM does not receive the proper voltage signal from the sensor.
Possible CauseUCS005QC

Harness or connector
(The sensor circuit is open or shorted.)

Vehicle speed sensor
DTC Confirmation ProcedureUCS005QD
CAUTION:

Always drive vehicle at a safe speed.

If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait
at least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode for
“A/T” with CONSULT-II.
2. Touch “START”.
3. Start engine and accelerate vehicle from 0 to 25 km/h (0 to 16
MPH).
4. If the check result is NG, go to AT-168, "
Diagnostic Procedure" .
WITHOUT CONSULT-II
1. Start engine.
2. Drive vehicle under the following conditions:
Selector lever position: “D” position
Vehicle speed: Higher than 25 km/h (16 MPH)
3. Perform self-diagnosis. Refer to AT-90, "
Diagnostic Procedure Without CONSULT-II" .
4. If the check result is NG, go to AT-168, "
Diagnostic Procedure" .

1. CHECK FUSE
Check that the following fuse is not blown.
OK or NG
OK >> GO TO 2.
NG >> If fuse is blown, be sure to eliminate cause of blown fuse before installing new fuse. Refer to PG-
4, "POWER SUPPLY ROUTING CIRCUIT" .
2. EQ SETTING CHECK
1. Ensure that subwoofer amp. connector B29 and audio unit harness connectors M43, M44 and M45 are
securely connected.
2. Turn the ignition switch to the ACC position.
3. Press the "AUDIO", "AUX", and "TUNE DOWN" switches simultaneously, the current EQ Setting will be
displayed.
Is "Woofer On" displayed?
YES >> GO TO 3.
NO >> Disconnect all audio unit harness connectors and wait for 2 minutes in order to reset the audio
unit. Reconnect audio unit connectors M44 and M45 first followed by M43 last. Repeat Steps 1
through 3 to confirm that "Woofer On" is now displayed.
3. POWER SUPPLY CIRCUIT CHECK
1. Turn ignition switch OFF.
2. Disconnect subwoofer connector.
3. Check voltage between the subwoofer and ground.
OK or NG
OK >> GO TO 4.
NG >>

Check connector housings for disconnected or loose
terminals.

Repair harness or connector.
4. GROUND CIRCUIT CHECK
1. Turn ignition switch OFF.
2. Check continuity between subwoofer harness connector B29
terminal 3 and ground.
OK or NG
OK >> GO TO 5.
NG >>

Check connector housings for disconnected or loose
terminals.

Repair harness or connector.
