Lexus ES: Inspection
INSPECTION
PROCEDURE
1. INSPECT FUEL SENDER GAUGE ASSEMBLY
CAUTION:
Perform the inspection in a well-ventilated area.
Do not perform the inspection near an open flame.
(a) Check that the float moves smoothly between F and E.
(b) Check the fuel sender gauge assembly voltage.
| (1) Apply 5 V between terminals 2 and 3. NOTICE: -
Be careful when connecting the leads, as the fuel sender gauge assembly may be damaged if the leads are connected to the wrong terminals.
-
Do not apply more than 6 V to terminals 2 or 3.
HINT: If a stable power supply is not available, connect 4 nickel-metal hydride batteries (1.2 V each) or equivalent in series. | | | *a | Component without harness connected (Fuel Sender Gauge Assembly) | | *b | Voltage Applied between Terminals | | |
| (2) Measure the voltage according to the value(s) in the table below. Standard Voltage: | Tester Connection | Float Level | Specified Condition | | 1 - 2 | F | 4.255 to 4.605 V* | | Between F and E | 0.345 to 4.605 V* (Gradually changes) | | E | 0.345 to 0.695 V* | *: The output voltage changes depending on the voltage applied to the terminals. Output voltage (F) = (0.851 x Voltage applied to terminals) to (0.921 x Voltage applied to terminals) Output voltage (E) = (0.069 x Voltage applied to terminals) to (0.139 x Voltage applied to terminals) If the result is not as specified, replace the fuel sender gauge assembly. | | | *a | Component without harness connected (Fuel Sender Gauge Assembly) | | |

INSTALLATION PROCEDURE 1. INSTALL FUEL SENDER GAUGE ASSEMBLY (a) for Type A: (1) Engage the claw to install the fuel sender gauge assembly to the fuel suction tube with pump and gauge assembly. NOTICE
PRECAUTION CAUTION:
Never perform work on fuel system components near any possible ignition sources.
Vaporized fuel could ignite, resulting in a serious accident.
Do not perform work on fuel s

DTC SUMMARY MALFUNCTION DESCRIPTION The hybrid vehicle control ECU detects that a safety device (interlock) is operated or that there is an open circuit in the detection circuit. (Even if an open circuit occurs while the vehicle is stopped, the system determines that the safety device was operated.)
DESCRIPTION The fuel pressure sensor (for low pressure side) replaces the fuel pressure with electrical signals and outputs them to the ECM. The ECM controls the optimal fuel pressure for the operation conditions to reduce the fuel pump power consumption and improve fuel economy. DTC No. Detec
