all of the C4 (C4-1 through C4-5) codes are accelerator sensor related. usually this is a bad connection at the sensor but can be caused by moisture in one of the connectors between the sensor and the engine controller. check the connectors for secure locking and make sure no moisture is present. this can also be caused by over rotation of the sensor (ie pedal to the floor with stop bolt missing or loose). remove the battery cable for about 15 secs after you check for problems and this should clear the code.

Showcased in the Virtual Expo

Fact of the week
The two internal cavities in our nose called nostrils function as separate organs. Each nostril has its own set of turbinates and olfactory receptors. The two independent organs work together through a mechanism called the nasal cycle, where one nostril is dominant for air intake while the other rests and is better at detecting scents.
