The post cat oxygen sensors monitor the readings from the cats and when they no longer do the job properly, these codes will set.
This cannot be oxygen sensors or they would set their own codes.
Yes, they are not performing at the level that they are supposed to and that is why it set the code.
The tests are ongoing while the truck is running and must fail more than one time to set these codes.
This diagnostic test is designed in order to measure the efficiency of the three-way catalytic converter (TWC) system. Catalytic convertor efficiency is a measure of its ability to store oxygen after converting the levels of hydrocarbon (HC), carbon monoxide (CO), and oxides of nitrogen (NOx) to less harmful gases. The control module is able to evaluate the catalyst efficiency once the vehicle has met the enable criteria and the vehicle is at idle instead of the steady cruise speeds used in the past.
Once the conditions for running this diagnostic trouble code (DTC) are met, the control module commands either a lean or rich air/ fuel ratio depending on the current state of the exhaust oxygen level. The control module issues a rich command if the exhaust is currently lean, or a lean command if the exhaust is currently rich. After completion of the first command, a second and opposite command is issued.
For example, if the control module were to command a rich mixture, the upstream heated oxygen sensor (HO2S) voltage would increase immediately. The rich mixture is delayed in reaching the downstream HO2S due to the conversion process occurring within the converter. The higher the efficiency, the more the delay before the rich or lean mixture is detected by the downstream oxygen (O2) sensor. As a result of the lower conversion efficiency within a damaged or poisoned catalyst, the delay in the rich or lean mixture reaching the downstream O2 sensor is significantly shorter. This DTC monitors the amount of time required for both the upstream and downstream HO2S voltages to cross a calibrated voltage threshold in response to the rich or lean command.
and ALL of these must be ok, or those codes will not set.
• | No active secondary air injection (AIR) system DTCs |
• | No active camshaft position (CMP) sensor DTCs |
• | No active engine coolant temperature (ECT) sensor DTCs |
• | No active exhaust gas recirculation (EGR) DTCs |
• | No active fuel trim DTCs |
• | No active idle air control (IAC) DTCs |
• | No active intake air temperature (IAT) sensor DTCs. |
• | No active mass air flow (MAF) sensor DTCs |
• | No active manifold absolute pressure (MAP) sensor DTCs |
• | No active heated oxygen sensor (HO2S) DTCs |
• | No active transmission DTCs |
• | No active evaporative emissions (EVAP) system DTCs |
• | No active throttle position (TP) sensor DTCs |
• | No active vehicle speed sensor (VSS) DTCs |
• | No active misfire DTCs |
• | The engine speed is 900 RPM or more for more than 35 seconds since the last idle period. |
• | The engine has been running for more than 346 seconds and the long term fuel trim is stable. |
• | The predicted catalyst temperature is more than 475°C (887°F). |
• | The system is in Closed Loop mode. |
• | The barometric pressure (BARO) is 73 kPa or more. |
• | The IAT is between −7°C –117°C (20°F – 167°F). |
• | The ECT is between 75°C – 117°C (167°F – 243°F). |
• | The engine has been idling for more than 60 seconds. |
• | The actual engine speed is within 100 RPM of the desired idle speed. |
So this can only be bad cats. replacing the cats should help.Good luck carry on.-------
