Honda Element. Manual — part 25

Based on these characteristics, the engine control module (ECM)/powertrain control module (PCM) looks at the
relationship between purge flow and fuel tank pressure, and when the fuel tank pressure decreases very little as
the purge flow increases, a loose fuel cap is detected.

< Above failure detection is normally operated during purge >

Malfunction Threshold

The output from the fuel cap monitor is 0.071 or more for at least 12 seconds (when there is no NG judgment
history in this drive cycle).

Confirmation Procedure with the HDS

Do the EVAP FUNCTION TEST in the INSPECTION MENU with the HDS.

Driving Pattern

1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator

fan comes on.

2. Let the engine idle for at least 12 seconds.

3. Drive the vehicle immediately at a speed between 45 - 75 mph (72 - 120 km/h) for at least 12 minutes.



Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.

Diagnosis Details

Conditions for illuminating the fuel fill cap caution

1. When a loose fuel fill cap is judged by this detection, the fuel fill cap caution is displayed. At this time,

the DTC is not stored.

2. When the first drive cycle leak judgement (Temporary DTC stored) is implemented at a 0.02 inch leak or

a 0.09 inch leak, the fuel fill cap caution is displayed when the ignition switch is turned on the next time.

Conditions for clearing the fuel fill cap caution

1. When the fuel fill cap caution is displayed by the first drive cycle leak judgement (Temporary DTC

stored) at a 0.02 inch leak or a 0.09 inch leak, the fuel fill cap caution goes out when the next failure
occurs (second drive cycle) and P0457 is stored. (MIL illuminates by the leak detection)

2. When normally judged by a 0.02 inch leak or a 0.09 inch leak after the fuel fill cap caution is displayed,

the fuel fill cap caution goes out when the ignition is turned on the next time. (P0457 is not stored at this
time)

3. When driving three times without this failure detection and a 0.02 inch leak or a 0.09 inch leak detection

is not done after the fuel fill cap caution is displayed, the fuel fill cap caution goes out. (P0457 is not
stored at this time)

4. Use the Clear command of scan tool to erase the caution. This is also applied to cancelling the battery

caution. The caution is erased when the MIL is illuminated.

RANGE/PERFORMANCE PROBLEM

Fig. 69: Fuel Level Sensor (Fuel Gauge Sending Unit) Malfunction - Graph

General Description

The fuel level sensor is incorporated with the fuel pump and installed in the fuel tank. Using a built-in
potentiometer and float, it converts the movement of the float into electrical signals that correspond to the fuel
level, and it indicates the amount of fuel in the fuel tank. If the engine control module (ECM)/powertrain
control module (PCM) receives no change in the fuel level sensor output after driving for a specified number of
miles, it detects a malfunction and stores a DTC.

Enable Conditions

ENABLE CONDITIONS

Malfunction Threshold

The change in the fuel level sensor output is 3.5 % or less.

Driving Pattern

Drive for the specified mileage under Enable Conditions without refueling (Turning the ignition switch off is
acceptable).



Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.

Diagnosis Details

Conditions for illuminating the indicator

When a malfunction is detected, the DTC and the freeze frame data are stored in the ECM/PCM memory. The
MIL does not come on.

Conditions for clearing the DTC

The DTC and the freeze frame data can be cleared by using the scan tool Clear command or by disconnecting
the battery.
