Honda Element. Manual — part 81

MONITOR DESCRIPTION

Enable Conditions

ENABLE CONDITIONS

Malfunction Threshold

The difference between the BARO sensor output and the MAP sensor output is 28 kPa (8.1 in.Hg, 204 mmHg)
or more for at least 2.5 seconds.

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. Drive the vehicle with the throttle position as specified under Enable Conditions for at least 2.5 seconds.



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

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.

Execution

Once per driving cycle

Sequence

None

Duration

2.5 seconds or more

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.

DTC P2228: BAROMETRIC PRESSURE (BARO) SENSOR CIRCUIT LOW VOLTAGE

Fig. 233: Barometric Pressure (BARO) Sensor Circuit Diagram

Fig. 234: Barometric Pressure (BARO) Sensor Output Voltage - Graph

General Description

The barometric pressure (BARO) sensor is built into the engine control module (ECM)/powertrain control
module (PCM), and it monitors atmospheric pressure. The ECM/PCM estimates appropriate intake airflow from
the manifold absolute pressure (MAP) sensor output voltage and BARO sensor output voltage. If the BARO
sensor output voltage is a specified value or less, the ECM/PCM detects a malfunction and a DTC is stored.
