Driving Pattern

Fig. 44: Vehicle Driving Pattern

1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator

fan comes on.

2. Drive the vehicle at a speed between 15 - 75 mph (24 - 120 km/h) for at least 3 minutes.

3. Stop the vehicle, and let the engine idle for at least 3 minutes.



When freeze frame data is stored, drive the vehicle under those conditions instead of Driving
Patterns 2 or 3.



When you have difficulty duplicating the DTC because of road conditions and traffic situations,
repeat the driving pattern several times.



Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.

Diagnosis Details

Conditions for illuminating the MIL

Misfire Type 1: Under high rpm or high load conditions: The MIL blinks once per second if a type 1 misfire
(catalyst damaging) occurs, and a Temporary DTC is stored. If the type 1 misfire ceases, the MIL goes off. If a
type 1 misfire occurs during the next (second) drive cycle, the MIL blinks at the first misfire occurrence, and
the DTC and the freeze frame data are stored. The MIL remains on steady if the type 1 misfire ceases.

Under normal driving conditions: The MIL blinks once per second if a type 1 misfire occurs a third time, and a
Temporary DTC is stored. If a type 1 misfire occurs during the next (second) drive cycle, the MIL blinks during
the third type 1 misfire occurrence, and the DTC and the freeze frame data are stored. If the type 1 misfire
ceases, the MIL remains on steady.

Misfire Type 2: When a type 2 misfire (emission-related but not severe enough to immediately damage the
TWC) occurs within the first 1,000 engine revolutions after engine start-up, a Temporary DTC is stored.

If a type 2 misfire occurs after the first 1,000 engine revolutions after engine start-up, a Temporary DTC is
stored during the fourth type 2 misfire occurrence.

If a type 2 misfire occurs during the next (second) drive cycle, the MIL comes on, and the DTC and the freeze
frame data are stored.

Conditions for clearing the MIL

The MIL will be cleared if the malfunction does not recur during three consecutive drive cycles in which the
engine conditions are similar to the first time the malfunction was detected.

The MIL, the DTC, the Temporary DTC, and the freeze frame data can be cleared by using the scan tool Clear
command or by disconnecting the battery.

DTC P0325 (23): ADVANCED DIAGNOSTICS

DTC P0325: KNOCK SENSOR CIRCUIT MALFUNCTION

Fig. 45: Knock Sensor Circuit Diagram

General Description

The knock sensor is mounted on the engine block and detects engine knocking. The vibrations caused by the
knocking are converted into electrical signals through the piezo ceramic element. The engine control module
(ECM)/powertrain control module (PCM) controls the ignition timing based on the electrical signals. If the
signals from the knock sensor do not vary for a set time, the ECM/PCM detects a malfunction and stores a
DTC.

No signals from the knock sensor are detected for at least 5 seconds.

Driving Pattern

1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator

fan comes on.

2. Hold the engine speed at 3,000 - 4,000 rpm for at least 10 seconds.

Diagnosis Details

Conditions for illuminating the MIL

When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the
ECM/PCM memory.

Conditions for clearing the MIL

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic
runs.

The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by
disconnecting the battery.

Fig. 46: Crankshaft Position Sensor Circuit Diagram

General Description

The crankshaft position (CKP) sensor consists of a rotor and a semiconductor that detects rotor position. When
the engine starts, the rotor turns and the magnetic flux in the semiconductor device changes. The changes of
magnetic flux are converted into pulsing signals to the engine control module (ECM)/powertrain control module
(PCM). The CKP sensor detects injection/ignition timing for each cylinder and engine speed.

If no pulsing signals from the CKP sensor are detected, a malfunction is detected and a DTC is stored.
