Bank 1 is on drivers side and has two sensors #1 and #2. The #1 is before catalytic converter and #2 is after.

Hi the p1684 means the battery has been disconnected within the last 50 starts, the P0135 is Oxygen O2 Sensor Heater Circuit Malfunction (Bank1, Sensor1), you may have notived an increase in fuel consumption. and the P0456 code means evaporated emissions system -small leak detected the causes could be either A small leak in any of the EVAP hoses or fuel tank hoses, a small leak in the purge valve or vent valve or the EVAP Canister may be leaking
Hope this helps

Air/Fuel Sensors are mounted upstream of the catalytic converter. They are located on the exhaust manifold side of the catalytic converter (pre-converter - Sensors 1). Oxygen Sensors are mounted downstream of the catalytic converter (post-converter - Sensors 2). The catalytic converter has two chambers (left and right). Bank1 is left, drivers side. Bank2 is right, passengers side. The Bank2 Sensor1 sensor (Air/Fuel Sensor) is the one located on the 'right and ahead' of the converter. The PowerTrain Control Module (PCM) is reporting that the heater or circuit ( wiring / plug-in) of the sensor is malfunctioning.

P0133 HO2S Slow Response Bank 1 Sensor 1 and P1134 HO2S Transition Time Ratio Bank1 Sensor1
Both of these codes are common for the Oxygen Sensor. I hope this helps.

There are 4 oxy. sensors listed for your truck. they're located as follows
Left exaust before catalytic converter. bank1 sensor1-after cat conv.
bank1 sensor2. right exaust before cat.conv. bank2 sensor1-after cat.
conv. bank2 sensor2. Hope this helps.

The PO125 is an indication of an engine running too cold-as if the thermostat were stuck open.For some reason it often sets with the PO1135 even when the engine runs at normal temp.A scan tool will indicate exactly how hot the engine is,don't trust the dash gauge. The PO1135 is a heater circuit fault in the bank1 sensor1 air fuel ratio sensor or oxygen sensor. Bank 1 is the REAR bank on this car...that O2 sensor is not much fun.PO500 is a vehicle speed sensor fault-does the speedo work correctly?it is located in the transmission near the back of the case. once again the scan tool will read vehicle speed and can aid in further diagnosis.

the first one on the right hand side before the catalytic converter

Bank one is the side that cylinder 1 is located. Sensor 1 is in front of the cat converter, sensor 2 is behind the converter. So Sensor 1 bank 1 is the RIGHT FRONT SENSOR.

Bank 1 is the same side as cylinder #1 and bank 2 is the same side as cylinder #2. Good luck and hope this helps.
