FAIL-SAFE CHART
If any of the following DTCs are set, the ECM enters fail-safe
mode to allow the vehicle to be driven temporarily.
HINT:
• *1: The vehicle can be driven slowly when the accelerator
pedal is depressed firmly and slowly. If the accelerator
pedal is depressed quickly, the vehicle may speed up and
slow down erratically.
• *2: Misfire related fail-safe operations occur when catalyst
overheat malfunctions occur.

MONITOR DESCRIPTION
After the ECM sends the "target" duty-cycle signal to the OCV, the ECM monitors the OCV current to
establish an "actual" duty-cycle. The ECM detects a malfunction and sets a DTC when the actual duty-
cycle ratio varies from the target duty-cycle ratio.

HINT:
• If DTC P0011 or P0012 is displayed, check the bank 1 VVT system circuit.
• Bank 1 refers to the bank that includes cylinder No. 1.
• If DTC P0021 or P0022 is displayed, check the bank 2 VVT system circuit.
• Bank 2 refers to the bank that does not include cylinder No. 1.
• 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) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position and turn the
tester on.
(c) Select the following menu items: DIAGNOSIS /
