2002 Mazda B3000 ProblemsCheck Engine Light Illuminated, code for Camshaft Position Sensor, Runs Poorly
The Check Engine Light may come on and the engine will run poorly. During diagnosis the technician may find a trouble code for the Camshaft Position Sensor (CMP), P0340. It is recommended to check the CMP driveshaft for looseness in the housing because if the shaft is loose, a new sensor will be damaged again. If the shaft has play, the CMP sensor and housing unit will need to be replaced. Our technicians recommend using the factory type timing tool for the replacement procedure.
A dirty, or contaminated mass airflow (MAF) sensor can cause the engine to run poorly. There may be a Check Engine Light with trouble codes relating to the MAF sensor, P0102 and/or P0103. In some cases, carefully cleaning the sensor element will fix the problem, but replacement may be required.
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.

Just replaced front left wheel bearings for a previous noise (grinding like) problem... it fixed it for a week (150 miles), now it's making a humming noise... it gets loudest at 40 MPH...
Could it be a cheap after-market brand bearing causing it? made in China, for O'Reilly's Parts...
