DO you also have any driving issues or just the check engine light is on?

The code p0320 is for a faulty crank sensor signal which can be caused by a faulty crank sensor, cam sensor or incorrect timing. Since engine ois running smooth it could be a faulty crank sensor.

P0135, p0141, p0155 and p0161 are for all four O2 sensor heater been faulty. It could be caused by fuse #16 in the Power Distribution Center (PDC) under the hood, if good then check the G104 ground, it is on the right side of the engine block towards the rear. If good then check the power to the heaters at the O2 sensors with the engine running.

P0442 is for an EVAP leak present in the system

P0700 means that there is a code in the TCM. The TCM will need to be scanned for transmission related code.

Most common reasons for DTC p0442 is a faulty gascap, EVAP hose leak by the evap canister or the purge valve.

On this vehicle the TCM codes can also be triggered due to a faulty crank sensor or even a low battery but codes will need to be scanned to pinpoint.
