2008 Mazda B4000 Problems

Rough Running Idle, Erratic Speedometer Operation, ABS Light Illuminated, Check Engine Light, and Automatic Transmission Shifting Problems

Water intrusion into a connector (X309) located under the cab, beneath the driver's seat, can cause a rough idle, erratic speedometer operation, ABS Light and Check Engine Light illumination, and automatic transmission shifting problems. If needed, connector repair parts are available from Mazda dealers, and possibly some Ford dealers.

Crank but No Start Condition and No Fuel Pressure

If the engine cranks but does not start, it may be caused by a tripped inertia switch. Switch the key to "ON" and the fuel pump should be heard running for a second or two. Listen at the gas filler if necessary. The inertia switch is located on the firewall and can be tripped when the parking brake is set too hard and then released. The inertia switch should be reset, and will click when it is reset.

Runs Poorly, Possible Check Engine Light

A dirty, or contaminated mass airflow sensor (MAF) can cause the engine to run poorly. The Check Engine Light may or may not illuminate.  MAF sensor related fault codes P0102 and/or P0103 may be stored. In some cases, carefully cleaning the sensor element will fix the problem. If not, replacement of the sensor may be required.
