Fig. 52: Vehicle 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 at a speed between 45 - 75 mph (73 - 120 km/h) for at least 5 minutes, to warm up the 

TWC.  

3. Set a vehicle speed of 55 mph (88 km/h) on the cruise control, and drive for at least 1 minute. 



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. 

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.

MALFUNCTION

Fig. 53: Evaporative Emission Control System Canister Purge Valve Circuit Diagram 

General Description 

The evaporative emission (EVAP) canister purge valve is attached to the vacuum port between the EVAP 
canister and the intake manifold. The engine control module (ECM)/powertrain control module (PCM) does not 
turn on the EVAP canister purge valve when the engine coolant temperature is 131 °F (55 °C) or less. The 
ECM/PCM adjusts the amount of fuel vapor sent to the engine by controlling the EVAP canister purge valve 
duty cycle. 

When the return signal does not change according to the EVAP canister purge valve output for a set time, the 
ECM/PCM detects a malfunction, and a DTC is stored.
