PSP SWITCH

PSP SWITCHPFP:49761
Component DescriptionEBS011G9
The power steering pressure switch is attached to the power steer-
ing high-pressure tube and detects a power steering load.
When a power steering load is detected, it signals the ECM. The
ECM adjusts the fuel injector pulse width to increase the idle speed
and adjust for the increased load.

2. PERFORM FUEL PUMP LEARNING VALUE CLEARING
NOTE:
If the DTC is detected because of air mixed with fuel (i.e.: caused by lack of fuel), it may become normal by
performing following procedure.
With CONSULT-II
1. Turn ignition switch ON.
2. Perform Fuel Pump Learning value clearing. Refer to EC-1370, "
Fuel Pump Learning Value Clearing" .
3. Start engine and let it idle for at least 60 seconds.
4. Select “SELF-DIAG RESULT” mode with CONSULT-II.
5. Touch “ERASE”.
6. Perform EC-1434, "
DTC Confirmation Procedure" , again.
7. Is DTC detected again?
Without CONSULT-II
1. Turn ignition switch ON.
2. Perform Fuel Pump Learning Value Clearing. Refer to EC-1370, "
Fuel Pump Learning Value Clearing" .
3. Start engine and let it idle for at least 60 seconds.
4. Erase the Diagnostic Test Mode II (Self-diagnostic results) memory. Refer to EC-1375
.
5. Perform EC-1434, "
DTC Confirmation Procedure" , again.
