Possible cause

P1556

BAT TMP SEN/CIRC
(Battery temperature sensor cir-
cuit low input)

Signal voltage from Battery temperature 
sensor remains 0.16V or less for 5 sec-
onds or more.

• Harness or connectors

[Battery current sensor (Battery tem-
perature sensor) circuit is shorted.]
[Camshaft position sensor (PHESE) 
circuit is open or shorted.]
(Accelerator pedal position sensor 2 
circuit is shorted.)
(Throttle position sensor circuit is 
shorted.)

• Battery current sensor (Battery tem-

perature sensor)

• Camshaft position sensor (PHESE) 
• Accelerator pedal position sensor
• Throttle position sensor

P1557

BAT TMP SEN/CIRC
(Battery temperature sensor cir-
cuit high input)

Signal voltage from Battery temperature 
sensor remains 4.84V or more for 5 sec-
onds or more.

3.

Check the continuity between battery current sensor harness connector and ECM harness connector.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair open circuit.

3.

CHECK SENSOR POWER SUPPLY CIRCUIT

Check harness for short to power and short to ground, between the following terminals.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair short to ground or short to power in harness or connectors.

4.

CHECK COMPONENTS

Check the following.
• Camshaft position sensor (PHESE) (Refer to 

EC-276, "Component Inspection"

.)

• Battery current sensor (Refer to 

EC-351, "Component Inspection"

.)

• Throttle position sensor (Refer to 

EC-198, "Component Inspection"

.)

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Replace malfunctioning component.

5.

CHECK APP SENSOR

Check APP sensor. Refer to 

EC-405, "Component Inspection"

.
