P0328 - Knock Sensor 1, circuit high inout.
This is a fault with the knock sensor and is engine related. Quite often the sensor is the one at fault but before replacing it, check the wiringcircuits.
DTC P0741: TORQUE CONVERTER CLUTCH SOLENOID PERFORMANCE (SHIFT SOLENOID VALVE DSL)
SYSTEM DESCRIPTION
The ECM uses the signals from the throttle position sensor, Air-flow meter and crankshaft position sensor to monitor the engagement condition of the lock up clutch.
Then the ECM compares the engagement condition of the lock up clutch with the lock up schedule in the ECM memory to detect mechanical problems of the shift solenoid valve DSL, valve body and torque converter clutch.
INSPECTION PROCEDURE
1. INSPECT TRANSMISSION WIRE (DSL)
a. Disconnect the transmission wire connector from the transaxle.
B. Measure resistance between the terminal DSL and body ground.
OK:
Resistance: 11 to 13 ohm at 20 °C (68 °F)
NG: Go to step 3
OK: Go to next step.
2. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM)
a. Connect the transmission wire connector.
B. Disconnect the ECM connector.
C. Measure the resistance between terminals DSL and E1.
OK:
Resistance: 11 to 13 ohm at 20 °C (68 °F)
NG: REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go to next step.
3. INSPECT SHIFT SOLENOID VALVE DSL
a. Remove the shift solenoid valve DSL.
B. Measure the resistance between the terminal DSL of shift solenoid valve and the solenoid body.
OK:
Resistance: 11 to 13 ohm at 20 °C (68 °F)
c. Connect positive (+) lead to the terminal of solenoid connector, negative (-) lead to the solenoid body.
OK:
The solenoid valve makes an operating noise.
NG: REPLACE SHIFT SOLENOID VALVE DSL
OK: Go to next step.
4. CHECK TRANSMISSION WIRE
NG: REPAIR OR REPLACE TRANSMISSION WIRE
OK: Go to next step.
5. INSPECT TRANSMISSION VALVE BODY ASSY
NG: REPAIR OR REPLACE TRANSMISSION VALVE BODY ASSY
OK: Go to next step.
6. INSPECT TORQUE CONVERTER CLUTCH ASSY
NG: REPLACE TORQUE CONVERTER CLUTCH ASSY
OK: REPAIR AUTOMATIC TRANSAXLE ASSY
