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) Engage the claw to install the fuel sender gauge assembly to the fuel sub-tank. NOTICE: Be careful not to bend the arm of the fuel send
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
