KlaroFault codes › P08xx
P08xx fault codes: Transmission (continued)
A continuation of the previous family: transmission controls, solenoids and sensors. Diagnosis nearly always requires the manufacturer's documentation.
How to read this code
The letter P names the system: Powertrain. The next digit, 8, locates the fault: transmission (continued).
These codes are generic: they mean the same thing on every make. Some manufacturer tools display them with a two-digit suffix, such as P0101-00 or P010100: the suffix refines the fault type, and the base code keeps its meaning.
