Honda Element. Manual - part 2

Malfunction Threshold 

The difference between the amount of intake air measured by the MAF sensor and the amount of intake air 
calculated from the MAP sensor output is out of the normal area for at least 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. Let the engine idle for at least 5 seconds.  

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.

General Description 

The mass airflow (MAF) sensor is attached to the intake air passage, and it measures the amount of intake 
airflow. The MAF sensor is a hot wire airflow meter. The airflow cools the electrically heated wire that is

mounted in the air passage. The engine control module (ECM)/powertrain control module (PCM) determines 
the amount of intake airflow by detecting the current that is required to keep the hot wire at a constant 
temperature. The lower limit of the MAF sensor output is specified. If the output is below that limit, the 
ECM/PCM detects a malfunction and stores a DTC.
