DTC index

NOTE:

Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5

digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last

2 digits give extra information read by the manufacturer-approved diagnostic system).

DTC

Description

Possible causes

Action

P010100

Mass or volume air flow A

circuit range/performance

Blocked air cleaner

Air intake leak

Engine breather leak

Mass air flow (MAF) sensor
