INSPECTION PROCEDURE
HINT:
Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition
information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data
can be helpful in determining whether the vehicle was running or stopped, whether the engine was
warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of
a malfunction.
(a) Disconnect the C18 or C19 VVT sensor connector.
(b) Measure the voltage according to the value(s) in the
table below.
Standard voltage
(c) Reconnect the VVT sensor connector.

MONITOR DESCRIPTION
The battery supplies electricity to the ECM even when the ignition switch is off. This power allows the
ECM to store data such as DTC history, freeze frame data and fuel trim values. If the battery voltage falls
below a minimum level, these memories are cleared and the ECM determines that there is a malfunction
in the power supply circuit. When the engine is next started, the ECM illuminates the MIL and sets the
DTC.
HINT:
If DTC P0560 is set, the ECM does not store other DTCs.

INSPECTION PROCEDURE
HINT:
• The following troubleshooting flowchart is based on the premise that the engine is cranked normally. If
the engine will not crank, proceed to the problem symptoms table (See page ES-27).

DESCRIPTION
The park/neutral position switch detects the shift lever position and sends signals to the ECM.
HINT:
After confirming DTC P0705, use the intelligent tester to confirm the PNP switch signal in the ALL menu
(to reach the ALL menu: DIAGNOSIS / ENHANCED OBD II / DATA LIST / ALL).
WIRING DIAGRAM
Refer to DTC P0705 for 2WD model (See page AX-40) or 4WD model (See page AX-40).
INSPECTION PROCEDURE
Refer to DTC P0705 for 2WD model (See page AX-41) or 4WD model (See page AX-41).
HINT:
Read freeze frame data using the intelligent tester or OBD II scan tool. The ECM records vehicle and
driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting,
freeze frame data can help determine if the vehicle was running or stopped, if the engine was warmed up
or not, if the air-fuel ratio was LEAN or RICH, and other data from the time the malfunction occurred.
