DTC P0182, P0183 FUEL PUMP TEMPERATURE SENSOR
DTC P0182, P0183 FUEL PUMP TEMPERATURE SENSOR
PFP:16700
Description
EBS01558
Fuel pump temperature sensor is built in the fuel pump. The sensor detects the fuel temperature in the fuel
pump and calibrates the fuel injection amount change by fuel temperature.
CONSULT-II Reference Value in Data Monitor Mode
EBS01559
Specification data are reference values.
ECM Terminals and Reference Value
EBS0155A
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
On Board Diagnosis Logic
EBS0155B
The MI will not light up for these self-diagnoses.
DTC Confirmation Procedure
EBS0155C
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
1.
Turn ignition switch ON.
2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
Wait at least 5 seconds.
4.
If DTC is detected, go to
EC-450, "Diagnostic Procedure"
.
