If the engine was not up to temp might be why these were "pending."

(P0432) CATALYTIC 2/1 EFFICIENCY (CONTINUED) When Monitored and Set Condition
• When Monitored: The Powertrain Control Module (PCM) monitors the engine at operating temperature, in closed loop, engine load between 22–52%, the Three Way Catalytic (TWC) converter temperature is greater than 380°C (716°F), and no O2 Sensor or engine misfire faults.
• Set Condition: The amplitude of the O2 Sensor Signal downstream of the TWC exceeds 75% of the amplitude of the O2 Sensor Signal upstream of the TWC for approximately 170 seconds.
POSSIBLE CAUSES
O2 SENSOR CONTAMINATION ENGINE EXHAUST LEAKS OR DAMAGE THREE WAY CATALYTIC CONVERTER FAILURE THREE WAY CATALYTIC CONVERTER DAMAGE

Diagnostic Test
1. INSPECT THE THREE WAY CATALYTIC CONVERTER Note: Diagnose any O2 Sensor DTC(s) before continuing with this diagnosis.
Note: Check for contaminants that may have damaged the O2 Sensor and TWC converter: contaminated fuel, unapproved silicone products, oil or coolant and repair as necessary.
Note: Engine exhaust leaks can be the cause of this DTC. Inspect the exhaust system for leaks before diag- nosing this DTC.
Note: Always perform diagnostics with a fully charged battery.
