DESCRIPTION Refer to DTC P032511. Click here
 HINT: When
DTC P032515 or P033015 is stored, the ECM enters fail-safe mode. During
fail-safe mode, the ignition timing is delayed to its maximum
retardation. Fail-safe mode continues until the engine switch is turned
off. |

MONITOR DESCRIPTION
If
the output voltage transmitted by the knock control sensor remains high
for 1 second or more, the ECM interprets this as a malfunction in the
sensor circuit, and stores this DTC. MONITOR STRATEGY |
Related DTCs | P0328: Knock control sensor (bank 1) range check (high voltage)
P0333: Knock control sensor (bank 2) range check (high voltage) | |

HINT:
- After repair has been completed, clear the DTC and then check that the
vehicle has returned to normal by performing the following All Readiness
check procedure.
Click here
- When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- Connect the Techstream to the DLC3.
- Turn the engine switch on (IG).
- Turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the engine switch off and wait for at least 30 seconds.
- Start the engine and wait 5 minutes [A].
- Turn the Techstream on.
- Enter the following menus: Powertrain / Engine / Trouble Codes [B].
- Read the pending DTCs.
HINT:
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.
- Enter the following menus: Powertrain / Engine / Utility / All Readiness.
- Input the DTC: P032515 or P033015.
- Check the DTC judgment result.

PROCEDURE |
1. | CHECK TERMINAL VOLTAGE (POWER SOURCE OF KNOCK CONTROL SENSOR) |
|
*a | Front view of wire harness connector
(to Knock Control Sensor) | |
*b | Bank 1 | |
*c | Bank 2 |
(a) Disconnect the knock control sensor connector. (b) Turn the engine switch on (IG).
(c) Measure the voltage according to the value(s) in the table below. Standard Voltage: |
Tester Connection | Condition |
Specified Condition | |
U6-1 (EKNK) - U6-2 (KNK1) |
Engine switch on (IG) |
4.5 to 5.5 V | |
U7-1 (EKN2) - U7-2 (KNK2) |
Engine switch on (IG) |
4.5 to 5.5 V |
| NG |
 | GO TO STEP 3 |
|
OK |
 | |
| 2. |
INSPECT KNOCK CONTROL SENSOR | (a) Inspect the knock control sensor.
Click here HINT: Perform "Inspection After Repair" after replacing the knock control sensor.
Click here
| OK |
| GO TO STEP 4 |
| NG |
| REPLACE KNOCK CONTROL SENSOR |
| 3. |
CHECK HARNESS AND CONNECTOR (KNOCK CONTROL SENSOR - ECM) |
(a) Disconnect the knock control sensor connector. (b) Disconnect the ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance: |
Tester Connection | Condition |
Specified Condition | |
U6-2 (KNK1) - C56-82 (KNK1) |
Always | Below 1 Ω | |
U6-1 (EKNK) - C56-81 (EKNK) |
Always | Below 1 Ω | |
U7-2 (KNK2) - C56-114 (KNK2) |
Always | Below 1 Ω | |
U7-1 (EKN2) - C56-113 (EKN2) |
Always | Below 1 Ω | |
U6-2 (KNK1) or C56-82 (KNK1) - Other terminals |
Always | 10 kΩ or higher | |
U7-2 (KNK2) or C56-114 (KNK2) - Other terminals |
Always | 10 kΩ or higher |
| NG |
| REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
OK | |
| |
(a) Connect the Techstream to the DLC3.
