Laymans terms

This code means that the car's computer is having trouble understanding the voltage coming from the alternator. It's like when you can't hear your friend's voice clearly on the phone because of a bad connection.

Explanation

The car's computer monitors the voltage from the alternator to ensure it is within a specific range. If the voltage is outside of this range, the computer sets the P2CC2 code.

Technical description

The P2CC2 code indicates a problem with the voltage sense circuit B of the generator (alternator). This circuit is responsible for monitoring the output voltage of the alternator to ensure it is within the expected range. A deviation in the expected voltage range triggers this code.

Symptoms

• Check engine light on

• Battery warning light

• Electrical accessories not functioning correctly

Common Causes

• Faulty alternator

• Wiring issues in the voltage sense circuit

• Defective voltage regulator
