DTC P0111: IAT SENSOR 1 CIRCUIT RANGE/PERFORMANCE
| Description: Indicates the IAT rationality test has failed. This DTC indicates that the IAT value is higher than a calibrated value and could prevent one or more on-board diagnostic (OBD) monitors from completing.

DTC P013A: O2 SENSOR SLOW RESPONSE (BANK 1, SENSOR 2)
| Description: During a deceleration fuel shut-off (DFSO) event, the powertrain control module (PCM) monitors how quickly the rear heated oxygen sensor (HO2S) switches from rich to lean. The measured rate of the rich to lean switch is compared to a calibrated fault threshold value. The threshold value takes into account the level of oxygen in the catalyst, which has an impact on how quickly the rich to lean switch occurs. The test fails when the measured value is slower than the threshold value. | |||

DTC P013E: SENSOR DELAYED RESPONSE (BANK 1, SENSOR 2)
| Description: During a deceleration fuel shut-off (DFSO) event, the powertrain control module (PCM) monitors the rear heated oxygen sensor (HO2S) signal to determine if the signal is stuck in range. The PCM expects the signal to exceed a calibrated rich or lean value within a calibrated amount of time. If the signal voltage remains less than the rich value after a number of occurrences, the PCM intrusively controls the fuel system rich over increasing time periods in an attempt to force the signal to greater than the calibrated rich value. The test fails when after three consecutive intrusive attempts the signal cannot be forced greater than the calibrated rich value. Also, if the signal voltage remains greater than the lean value after a calibrated amount of time with the fuel injectors off, a counter is incremented. The test fails when after three consecutive occurrences the signal is not less than the calibrated lean value. | |||
|---|---|---|---|
| Possible Causes: Exhaust leaks before or near the HO2S Aftermarket exhaust accessories or performance modifications Ethanol content in the fuel Circuit intermittent Damaged HO2S | |||

DTC P0420: CATALYST SYSTEM EFFICIENCY (BANK 1)
| Description: Indicates the catalyst system efficiency is below the acceptable threshold. | |||
|---|---|---|---|
| Possible Causes: Use of leaded fuel Damaged heated oxygen sensor (HO2S) Out of range cylinder head temperature (CHT) sensor High fuel pressure Damaged exhaust manifold Damaged catalytic converter Oil contamination Cylinder misfiring Damaged exhaust system pipe Damaged muffler/tailpipe assembly | |||
| Diagnostic Aids: Under normal closed loop fuel conditions, high efficiency catalysts have a high level of oxygen storage that makes the switching frequency of the rear HO2S very slow and reduces the amplitude of the switches. As catalyst efficiency deteriorates, its ability to store oxygen declines and the rear HO2S signal begins to switch more rapidly with increasing amplitude. The powertrain control module (PCM) compares the signal line length of the rear HO2S to an expected signal line length of a rear HO2S with a deteriorated catalytic converter. Once beyond an acceptable limit the DTC is set. | |||

DTC P0457: EVAPORATIVE EMISSION SYSTEM LEAK DETECTED (FUEL CAP LOOSE/OFF)
| Description: The powertrain control module (PCM) continuously monitors the fuel level and retains the last updated value prior to the ignition switch being placed in the OFF position. After the ignition switch is placed in the ON position a new fuel level is taken and compared to the level recorded at ignition OFF. If the fuel level has increased, a flag is set in the PCM indicating the vehicle was refueled. If the evaporative emission (EVAP) monitor detects a gross leak while the refueling flag is set, an incorrectly sealed fuel tank filler pipe is suspected and the DTC is set. When the DTC sets, a message on the instrument cluster displays to instruct the driver to check the capless fuel tank filler pipe. | |||

| Possible Causes: Capless fuel tank filler pipe damaged or not sealed correctly | |||
| Diagnostic Aids: Verify the capless fuel tank filler pipe is sealed correctly. Install and remove the supplemental fueling adapter five times in the capless fuel tank filler pipe to clear debris on the seal.

Allow the vehicle to soak for 2-3 hours if necessary for the ECT to fall below 37.8°C (100°F). Start the engine without touching the accelerator pedal and allow the engine to idle for 15 seconds in park, then drive with the engine on for 6 minutes. If no DTCs are present and the malfunction indicator lamp (MIL) is not illuminated after idling with the engine on for 15 seconds in park and driving with the engine on for 6 minutes, carry out the key ON engine running (KOER) self-test to confirm that no DTCs are present and the repair is complete. | |||

DTC P144A: EVAPORATIVE EMISSION SYSTEM PURGE VAPOR LINE RESTRICTED/BLOCKED
| Description: The powertrain control module (PCM) monitors the evaporative emission (EVAP) system for a blocked fuel vapor tube between the fuel tank pressure (FTP) sensor and the fuel tank. During the initial phase of the EVAP monitor, the PCM closes the canister vent and a vacuum develops in the fuel vapor tubes and lines and in the fuel tank. The PCM monitors the FTP sensor to determine the amount of vacuum and how quickly the vacuum increases. The rate at which the vacuum increases is compared to an expected value. If the vacuum increases quicker than expected, a blocked fuel vapor tube is suspected and an intrusive test is carried out in the final phase of the EVAP monitor. If the intrusive test confirms a blockage a counter is incremented and once the counter reaches a calibrated number of completions, the DTC is set. | |||
