DTC 3

Self-diagnosis LED indicator blinks three times:

Most likely an electrical problem in the Manifold Absolute Pressure (MAP) Sensor system.








The MAP sensor converts manifold absolute pressure into electrical signals and inputs the ECU.

The Check Engine warning light and ECU LED may come on, indicating a system problem, when, in fact, there is a poor or intermittent electrical connection. First, check the electrical connections, clean or repair connections if necessary.
