![]() However, I think there is a real good possibility that if you find the problem with one of these circuits, the problem with the others will be close by. One may have a bad solenoid, while another has a loose connector pin, while the third one may have a broken wire. Other than this, the only thing I can tell you to do is to diagnose each circuit individually. If you do not see any obviously damaged wiring harnesses, I would be taking connectors loose and examining the pins inside them. Introduced in May, the 2002 Mazda Protegé5 hatchback is aimed at younger buyers who want both performance and practicality. It is possible that moisture and corrosion in a connector is shorting all of these circuits out. 2002 Mazda Protege5, how much is it to fix diagnostic trouble code P0031 and P0660 Vehicle: 2002 Mazda Protege5 p0031 p0660 mazda protege5 1 Answer. These wires all go through the same connectors, including the PCM connectors. 2002 Mazda Protege5, how much is it to fix diagnostic trouble code P0031 and P0660 0 votes. They like to crawl up into warm engine compartmens and chew on things like wiring harnesses and vacuum hoses.Īnother common denominator would be harness connectors. It is that time of year for lots of rodent damage. However, if these all showed up at the same time, I would be taking a hard look at the engine control wiring harnesses. Technically, you have three separate circuit failures no matter how it came about. ![]() If your check engine light has been on for quite a while, it is possible that each of these failures occured at separate times and you simply did not know about the second and third failures because the check engine light was already on due to the first failure. To replace it I think you might have to take off the throttle-body. You must take off the Intake tube to get a good view of it. The EGR Valve is located below the throttle-body. The search came up negative - no known issues for ANY of these codes. 2002 Mazda Protege5 with the FS2.0 Motor. I did do a Technical Service Bulletin (TSB) search for your vehicle to see if there were any known problems that regularly cause these codes or if there are any computer programming issues that can cause these. ![]() The failure of one of these circuits SHOULD have no effect on the other two. The circuits to each of these solenoids are SEPARATE circuits. Diagnostic Trouble Code (DTC) P0660 has a generic description of "Variable Inertia Charging System (VICS) Solenoid Valve Circuit Malfunction"ĭiagnostic Trouble Code (DTC) P1569 has a generic description of "Variable Tumble Control System (VCTS) Solenoid Valve Circuit, Low Input"ĭiagnostic Trouble Code (DTC) P1250 has a generic description of "Pressure Regulator Control (PRC) Solenoid Valve Malfunction" ![]()
