For codes p0171 and p0174 most likely it a dirty MAF, dirty TPS, dirty Idle sesor, or a vacum leak. To locate vacum leak spray starter fluid on the vacum hoses to find leak. in my case I did all of these and finally damn codes went away after fighting this headache for over a year. Good luck!!! hope this helps!!!

This is usually an oxygen sensor, replace the O2 sensor located above the catalytic converter before replacing the evaporator purge canister.

I received a P1154 OBD code error. It says


DTC P0131 or P0151
Circuit Description
Heated oxygen sensors (HO2S) are used for fuel control and post catalyst monitoring. Each HO2S compares the oxygen content of the surrounding air with the oxygen content in the exhaust stream. The HO2S must reach operating temperature to provide an accurate voltage signal. Heating elements inside the HO2S minimize the time required for the sensors to reach operating temperature. The powertrain control module (PCM) supplies the HO2S with a reference, or bias, voltage of about 450 mV. When the engine is first started, the PCM operates in Open Loop, ignoring the HO2S voltage signal. Once the HO2S reaches operating temperature and Closed Loop is achieved, the HO2S generates a voltage within a range of 0-1,000 mV that fluctuates above and below bias voltage. High HO2S voltage indicates a rich exhaust stream. Low HO2S voltage indicates a lean exhaust stream. If the PCM detects an HO2S voltage that stays below a specified value, DTC P0131 sets for HO2S bank 1 sensor 1, or DTC P0151 sets for HO2S bank 2 sensor 1.
