Dtc summary
Hint:
The canister pressure sensor is built into the canister pump module.
Description
The description can be found in the evap (evaporative emission) system (see page es-335).
Monitor description
If the canister pressure sensor output [pressure] rapidly fluctuates between less than 42.1 Kpa-a (315.9 Mmhg-a) and more than 123.8 Kpa-a (928.4 Mmhg-a), the ecm interprets this as an open or short circuit malfunction in the canister pressure sensor or its circuit, and stops the evap (evaporative emission) system monitor. The ecm then illuminates the mil and sets the dtc (1 trip detection logic).
If the canister pressure sensor voltage output fluctuates rapidly for 10 seconds, the ecm stops the evap system monitor. The ecm interprets this as noise from the canister pressure sensor, and stops the evap system monitor. The ecm then illuminates the mil and sets the dtc.
Alternatively, if the sensor voltage output does not change for 10 seconds, the ecm interprets this as the sensor being fixed/flat, and stops the monitor. The ecm then illuminates the mil and sets the dtc.
(Both the malfunctions are detected by 2 trip detection logic).
If the canister pressure sensor output [pressure] is below 42.1 Kpa-a (315.9 Mmhg-a), the ecm interprets this as an open or short circuit malfunction in the canister pressure sensor or its circuit, and stops the evap system monitor. The ecm then illuminates the mil and sets the dtc (1 trip detection logic).
If the canister pressure sensor output [pressure] is 123.8 Kpa-a (928.4 Mmhg-a) or more, the ecm interprets this as an open or short circuit malfunction in the canister pressure sensor or its circuit, and stops the evap system monitor. The ecm then illuminates the mil and sets the dtc (1 trip detection logic).

Inspection procedure
Notice:
Standard
Notice:
When replacing the canister, check the canister pump module interior and related pipes for water, fuel and other liquids. If liquids are present, check for disconnections and/or cracks in the following: 1) the pipe from the air inlet port to the canister pump module; 2) the canister filter; and 3) the fuel tank vent hose.
Go to step 8
Hint:
If the exhaust tailpipe has been removed, go to the next step before reinstalling it.

Hint:
If no pending dtcs are displayed on the tester, the repair has been successfully completed.

Diagnosis system
Check dlc3
Check the dlc3:
the power steering ecu uses can (iso11898-1)
and iso9141-2 for communication protocol. The
terminal arrangement of the dlc3 complies with
sae j1962 and matches the iso9141-2 format.

Battery temperature sensor circuit
Description
The battery temperature sensor installed on the battery current sensor
detects battery temperature.
A thermistor is integrated into the battery temperature sensor, and the
resistance in the battery
temperature sensor changes according to the battery temperature.
