Honda Element. Manual - part 83

 

 

Enable Conditions 

ENABLE CONDITIONS 

Malfunction Threshold 

The AFS-terminal voltage is 0.4 V or less for at least 5 seconds. 

Driving Pattern 

Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator fan 
comes on, then let it idle for 2 minutes. 

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.

General Description 

The secondary HO2S detects the oxygen concentration in the exhaust gas downstream of the three-way catalyst 
(TWC). 

The sensor output voltage characteristics are similar to the air/fuel ratio (A/F) sensor. The oxygen concentration 
is detected after the TWC during fuel feedback control using the A/F sensor, and it optimizes the fuel feedback 
control to maximize the effect of the TWC. If, after current is applied to the secondary HO2S heater, the 
secondary HO2S does not fluctuate and the output is stuck within the specified area, a malfunction is detected 
and a DTC is stored.

ENABLE CONDITIONS 

Malfunction Threshold 

The secondary HO2S output voltage is 0.650 V or less. 

Driving Pattern 

1. Start the engine. Let it idle until the radiator fan comes on.  

2. Drive the vehicle at a steady speed of 35 mph (57 km/h) or more for at least 24.6 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
