Honda Element. Manual — part 80

Malfunction Threshold

The ECT sensor 2 output voltage is 4.92 V or more for at least 2 seconds.

Diagnosis Details

Conditions for illuminating the MIL

When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the
ECM/PCM memory.

Conditions for clearing the MIL

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic
runs.

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

DTC P2195 (48): ADVANCED DIAGNOSTICS

DTC P2195: AIR/FUEL RATIO (A/F) SENSOR (SENSOR 1) SIGNAL STUCK LEAN

Fig. 230: Identifying Air/Fuel Ratio Sensor With Malfunction Diagnosis

General Description

When the air/fuel ratio (A/F) sensor (sensor 1) is properly connected to the engine wire harness, but not
installed in the exhaust pipe, the A/F feedback is not done properly even if the A/F sensor is active after starting
the engine. Thus, the exhaust emissions increase.

When the A/F sensor output stays out of the normal range after the A/F sensor becomes active, the engine
control module (ECM)/powertrain control module (PCM) detects that the A/F sensor is not properly installed
and a DTC is stored.

Enable Conditions

ENABLE CONDITIONS

Malfunction Threshold

A/F sensor output voltage is 3.67 V or more for at least 7 seconds.

Driving Pattern

Start the engine, then let it idle for at least 2 minutes.

Diagnosis Details

Conditions for illuminating the MIL

When a malfunction is detected during the first drive cycle, a Temporary DTC is stored in the ECM/PCM
memory. If the malfunction recurs during the next (second) drive cycle, the MIL comes on and the DTC and the
freeze frame data are stored.

Conditions for clearing the MIL

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic
runs.

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

Fig. 232: Barometric Pressure (BARO) Sensor Normal Operation And System Failure - Graph

General Description

The barometric pressure (BARO) sensor is built into the engine control module (ECM)/powertrain control
module (PCM) and monitors atmospheric pressure. When the throttle valve is wide open, the manifold absolute
pressure (MAP) sensor output is nearly equal to the BARO sensor output. Making use of this characteristic, a
malfunction can be detected in the BARO sensor output.

If the throttle position is beyond a value stored in the ECM/PCM that is used to detect "wide-open throttle," and
if the difference between the MAP sensor output and the BARO sensor output is equal to or greater than a set
value, a malfunction in the BARO sensor output is detected and a DTC is stored.
