Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hello, my name is***** by checking the resistance of the VTCS solenoid to determine if it is open or shorted. There is no published resistance specification, however, it should be about the same as the one next to it. Replace the solenoid if the resistance is no good. If the solenoid resistance s good, verify there is battery voltage to the VTCS solenoid when the key is on, if not, check for a broken wire in the engine wiring harness. If the above test results are good, check Blue/Orange wire of VTCS solenoid for an open or short to ground between the solenoid and terminal 4T of the Powertrain Control Module (PCM) connector. Of the two solenoids that are next to each other on the intake, this is the one to the driver's side of the vehicle. This solenoid is turned on (grounded by the PCM) below 140 degrees and below 3700 RPMs. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
