P0989-899 - Transmission Fluid Pressure Sensor / Switch "E" Circuit Low
(a) Disconnect the transmission wire connector.
(b) Turn the power switch on (IG).
(c) Measure the voltage according to the value(s) in the table below.
Standard voltage:
NOTICE:
Turning the power switch on (IG) with the hybrid vehicle control ECU connector disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.
(d) Turn the power switch off.
(e) Measure the resistance according to the value(s) in the table below.
Standard resistance (Check for open):
Standard resistance (Check for short):
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
21. CHECK CONNECTOR CONNECTION CONDITION (PB3 OIL PRESSURE SWITCH)
(a) Remove the oil strainer assembly Components.
(b) Check the connection of the PB3 oil pressure switch connector.
Result:
The connector is connected securely and there are no contact problems.
NG -- CONNECT SECURELY
OK -- Continue to next step.
22. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE)
(a) Disconnect the transmission wire connector.
(b) Disconnect the connector from the PB3 oil pressure switch.
(c) Turn the power switch on (IG).
(d) Measure the voltage according to the value(s) in the table below.
Standard voltage:
NOTICE:
Turning the power switch on (IG) with the transmission wire connector disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.
(e) Turn the power switch off.
(f) Measure the resistance according to the value(s) in the table below.
Standard resistance (Check for open):
Standard resistance (Check for short):
NG -- REPLACE TRANSMISSION WIRE Components
OK -- REPLACE PB3 OIL PRESSURE SWITCH Components
23. CHECK HARNESS AND CONNECTOR (HYBRID VEHICLE CONTROL ECU - TRANSMISSION WIRE)
(a) Disconnect the transmission wire connector and disconnect connector E55 from the hybrid vehicle control ECU.
(b) Turn the power switch on (IG).
(c) Measure the voltage according to the value(s) in the table below.
Standard voltage:
NOTICE:
Turning the power switch on (IG) with the hybrid vehicle control ECU connector disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.
(d) Turn the power switch off.
