Description
DTC P0101, P0102, P0103, P0112, P0113, P0117, P0118, P0120, P0121, P0122, P0123, P013A,  P013B,  P013E,  P013F,  P0171, P0172, P0220, P0222, P0223, P0300, P0335, P0336, P0365, P0366, P0442, P0443, P0446, P0449, P0455, P0496, P0506, P0507, P1381, or P2135 is not set  Before the ECM performs the idle test,  the vehicle must be driven under the following conditions The engine speed is greater than 1,000 RPM The engine run time is greater than 10 minutes Both conditions exist for greater than 1 minute The throttle is in the rest position  The intake air temperature IAT is between -20 to +85°C -4 to +185°F  The ignition voltage is greater than 11 V  The engine coolant temperature ECT is between 45-129°C 113-264°F  The barometric pressure BARO is greater than 70 kPa  The catalytic converter calculated temperature is less than 900°C 1,652°F  The vehicle speed is less than 2 km or h 1 mph  The short term fuel trim is learned  The short term fuel trim FT is between -10 and +10  percent  The engine is operating in Closed Loop  The transmission is not in P or N automatic transmission only  This diagnostic attempts one test during each valid idle period once the above conditions have been met  This diagnostic attempts up to 6 tests during each drive cycle
Cause
The ECM determines that the efficiency of the catalyst has degraded below a calibrated threshold
