P0501, P2159 VEHICLE SPEED SENSOR
Description
INFOID:0000000012197936
ECM receives a rear wheel sensor signal from ABS actuator and electric unit (control unit) via CAN communi-
cation to switch combustion for the direct injection gasoline system. For the direct injection gasoline system,
refer to
EC-51, "DIRECT INJECTION GASOLINE SYSTEM : System Description"

DTC DETECTION LOGIC
NOTE:
If DTC P0501 or P2159 is displayed with DTC UXXXX, first perform the trouble diagnosis for DTC UXXXX.
DTC CONFIRMATION PROCEDURE
1.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
TEST CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 9 V at idle.
>> GO TO 2.
2.
PERFORM DTC CONFIRMATION PROCEDURE
1. Start engine and let it idle for at least 5 seconds.
2. Check 1st trip DTC.
Is 1st trip DTC detected?
YES
>> Proceed to
.
NO
>> INSPECTION END
Diagnosis Procedure
INFOID:0000000012197938
1.
CHECK DTC WITH ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT)
With CONSULT
Check DTC with ABS actuator and electric unit (control unit). Refer to
.

>> Perform Diagnosis Procedure corresponding to DTC indicated.
DTC No.
Trouble diagnosis
(Trouble diagnosis content)
DTC detecting condition
Possible cause
P0501
VEHICLE SPEED SEN A
(Vehicle speed sensor A range/
performance)
ECM detects a rear LH wheel sensor mal-
function signal transmitted from the ABS ac-
tuator and electric unit (control unit) via CAN
communication at least for 5 seconds in a
row.
• Harness or connectors
(The CAN communication line is open
or shorted)
• Rear LH wheel sensor
• ABS actuator and electric unit (control
unit)
P2159
Vehicle speed sensor B
(Vehicle speed sensor B range/
performance)
ECM detects a rear RH wheel sensor mal-
function signal transmitted from the ABS ac-
tuator and electric unit (control unit) via CAN
communication at least for 5 seconds in a
row.
• Harness or connectors
(The CAN communication line is open
or shorted)
• Rear RH wheel sensor
• ABS actuator and electric unit (control
unit)

P0506 ISC SYSTEM
P0506 ISC SYSTEM
Description
INFOID:0000000012197939
The ECM controls the engine idle speed to a specified level through the fine adjustment of the air, which is let
into the intake manifold, by operating the electric throttle control actuator. The operating of the throttle valve is
varied to allow for optimum control of the engine idling speed. The crankshaft position sensor (POS) detects
the actual engine speed and sends a signal to the ECM.
The ECM controls the electric throttle control actuator so that the engine speed coincides with the target value
memorized in the ECM. The target engine speed is the lowest speed at which the engine can operate steadily.
The optimum value stored in the ECM is determined by taking into consideration various engine conditions,
such as during warming up, deceleration, and engine load (air conditioner, power steering and cooling fan
operation, etc.).

NOTE:
If DTC P0506 is displayed with other DTC, first perform the trouble diagnosis for the other DTC.
DTC CONFIRMATION PROCEDURE
1.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
If the target idle speed is out of the specified value, perform
, before conducting
DTC Confirmation Procedure.
TESTING CONDITION:
• Before performing the following procedure, confirm that battery voltage is more than 11 V at idle.
• Always perform the test at a temperature above
−10°C (14°F).
>> GO TO 2.
2.
PERFORM DTC CONFIRMATION PROCEDURE
1. Start engine and warm it up to normal operating temperature.
2. Turn ignition switch OFF and wait at least 10 seconds.
3. Start engine and run it for at least 1 minute at idle speed.
4. Check 1st trip DTC.
Is 1st trip DTC detected?
YES
>> Proceed to
.
NO
>> INSPECTION END
Diagnosis Procedure
INFOID:0000000012197941
1.
CHECK INTAKE AIR LEAK
1. Start engine and let it idle.
2. Listen for an intake air leak after the mass air flow sensor.
Is intake air leak detected?
YES
>> Discover air leak location and repair.
DTC No.
Trouble diagnosis
(Trouble diagnosis con-
tent)
DTC detecting condition
Possible cause
P0506
ISC SYSTEM
(Idle speed control system
RPM lower than expected)
The idle speed is less than the target idle
speed by 100 rpm or more.
