The 306 is a misfire for number 6 cylinder. I would replace the plugs and see if it takes care of it.
If not, then I would verify the fuel pressure to be sure there is sufficient fuel to the rail.
Standard Value: .................... 338 - 348 kpa (3.45 - 3.55 kgf/sq.cm, 49.0 - 50.5 psi)
The other codes are for the throttle body motor and the fuel pedal sensor.
I attached information below for you on those codes.
General Description 2138
The Electronic Throttle Control (ETC) system is made of the components throttle body, Throttle Position Sensor (TPS) 1&2 and Accelerator Position Sensor (APS) 1&2. The APS is mounted in the accelerator pedal to detect the opening angle of the accelerator pedal. It has 2 sensors to detect the accelerator position and a malfunction of the accelerator position sensor. The ECM judges the current opening angle of the accelerator pedal from APS 1&2, and the ECM controls the throttle motor based on these signals.
Checking output signals from APS 1 and 2 under detecting condition, if output signals difference between APS 1 and 2 are detected more than 4.5% for the specified number of times., PCM sets P2138. And then MIL (Malfunction Indication Lamp) turns on.
The Electronic Throttle Control (ETC) system is made of the components throttle body, Throttle Position Sensor (TPS) 1&2 and Accelerator Position Sensor (APS) 1&2. The throttle body contains the actuator, the throttle plate and the throttle position sensor (potentiometer), which are integrated in one housing. The actuator consists of a DC motor with a two-stage gear. The opening angle of the throttle valve is detected by the throttle position sensor which is mounted on the throttle body. And it provides feedback to the ECM to control the throttle motor in order to control the throttle valve opening angle properly in response to the driving condition.
If PCM recognizes vehicle state as forced limited power mode under detecting condition, it sets P2106 and then MIL (Malfunction Indication Lamp) turns on.
