yes you can do the manual version of the code clearing what some call the "pedal dance"

just a point to consider though
if you have not solved the issue the codes will not clear, they will remain persistent until you resolve the problem.

In alot of cases these codes get set because of a communication error between the throttle position sensors and also the MAF sensor. What has been consistent on these models is the wiring breaks right where they go into the connector(s) at the sensor. You have to locate the break and repair the wire first.
Most of the time you can just give the wire a nice tug and it will pull apart, then you can trim it back and solder it back together if it hasn't broken too close to the connector. If by some chance it breaks right at the connector there is a repair kit available from mfca/cat/Mitsubishi to repair the connector complete. It's basically a pre-made pigtail assy you use to replace the existing one.
