If a sensor or part is reading bad, be sure to visually inspect the wires coming out of that part, and verify conductivity with a multimeter. If electricity is reaching a certain spot in the wire, but not all the way to the sensor, that wire should be replaced. Conclusion Tracking down...
The next step, using a screwdriver to loosen and remove the screws used to fix the filter box. In this step, you also need to disconnect the power line associated with the MAF sensor in case your vehicle has any problems! However, be careful about the part of the plastic tang that fixe...
wasn't reading the proper voltage at idle, the OBD II system thought the throttle was open, but the MAF wasn't reading enough air flow. So it set a code for the MAF sensor when, in fact, a bad TPS reading was causing the glitch. One time-saver here is to hook up a DVOM, grap...
Many vehicles will provide a specific error code if a coil goes bad, but you can test a coil by disconnecting the spark plug wires and connecting an Ohmmeter (multimeter) to the top two pins. Compare the resistance you see on the Ohmmeter’s readout to the resistance for your specific ...
