WARNING: This page is about a different car, the 2024 Lexus TX 500h. However, it is still accessible from the selected car via links, so may be relevant.
- CHECK HARNESS AND CONNECTOR
HINT:
Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
Pre-procedure1
- Disconnect the No. 2 turbo pressure sensor connector.
- Turn the ignition switch to ON.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition Result C42-3 (VC) - C42-2 (E2) Ignition switch ON 4.5 to 5.5 V V C42-1 (PTA) - C42-2 (E2) Ignition switch ON 3.0 to 5.5 V V
Post-procedure1
- Turn the ignition switch off and wait for at least 30 seconds.
Pre-procedure2
- None
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition Result C42-3 (VC) - C42-1 (PTA) Ignition switch off 171 to 189 kΩ kΩ Result
Proceed to OK NG
Post-procedure2
- None
Result:
OK
REPLACE NO. 2 TURBO PRESSURE SENSOR. Refer to REMOVAL [09/2023 - ]
Result:
NG
See step 2
- CHECK HARNESS AND CONNECTOR (NO. 2 TURBO PRESSURE SENSOR - ECM)
Pre-procedure1
- Disconnect the No. 2 turbo pressure sensor connector.
- Disconnect the ECM connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition Result C42-3 (VC) - C26-102 (VPTA) Always Below 1 Ω Ω C42-1 (PTA) or C26-126 (PTA) - Body ground and other terminals Always 10 kΩ or higher kΩ Result
Proceed to OK NG
Post-procedure1
- None
Result:
OK
REPLACE ECM. Refer to REMOVAL [09/2023 - ]
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
