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. It is possible that moisture and corrosion in a connector is shorting all of these circuits out. These wires all go through the same connectors, including the PCM connectors. 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. Answer: The 2002 Mazda Protege VTCS solenoid valve location is found by. Mechanic's Assistant: VICS reads 0 ohms when I tested it. will replacing the variable intake air shutter valve actuator solve this problem Any help would be appreciated. Fixed a vacuum leak by replacing the intake hose it runs better but still has the idle issue when in gear and warmed up. Hello, I have a 2003 Protege5 and have replaced the VTCS/VICS solenoids and still keep getting the ERROR code P2009. mazda protege 5See complete 2003 Mazda Protege5 Specs at iSeeCars.73 in. However, if these all showed up at the same time, I would be taking a hard look at the engine control wiring harnesses. Q&A: Troubleshooting Rough Idle in 2002 Mazda Protege LX - VTCS Solenoid & V. In the Protege5, this same solenoid is used for EGR, VTCS, VICS, and PRC among others. 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. The search came up negative - no known issues for ANY of these codes. New Ignition Knock Detonation Sensor for Ford Mazda Protege 2.0L 01 03 - KS188 Fits select: 2002-2003 MAZDA PROTEGE PR5, 2001 MAZDA PROTEGE LX/ES. 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. Some threads say it could be the VICS system as well.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" And this makes perfect sense because I have a swapped computer from a Protege MP3 in my car, which will not recognize the VTCS system. I borrowed a pretty nice Bosch scanner from Oreilly's Auto Parts and it gave me a pending code of P0660 "Intake Manifold Tuning Valve, Control Circuit Open Bank 1".Īfter some research, the code seems to have to do with the VTCS solenoid. These DBElectrical alternators are trash! Doing keyword searches even on a Mazda dealer. At idle it is putting out 14.4-14.5 volts (which I call high) but when I turned everything on (high beam lights, heat, defrost, dome lights, blinkers, etc.) and revved motor pretty good I was hitting almost 17.5-17.9 volts!! THIS IS A 2 WEEK OLD ALTERNATOR. I cant find the part number for a 2002 Mazda Protege5 2.0 L VICS or the VTCS. The faster intake charge then has the inertia to swirl around the combustion chamber and more thoroughly mix with the fuel for combustion. The valve closes part of the intake path, increasing the velocity of the intake charge. Check the Pink ground wire for the VTCS solenoid valve back to terminal 73 of the Engine Control Module (ECM). Unplug and ohm the VTCS solenoid valve - specification is 22 - 26 ohms. Check the White/Red wire for good battery voltage to the VTCS solenoid valve with the key ON. I have inspected all connections (good), did voltage drop tests on connections (+) and (-) from battery to alternator (good), and voltage tests. The variable tumble control system (VTCS) was created to help emissions at low RPMs. Verify the VTCS solenoid valve connector is clean and tight. And if I have to return or warranty it there is a store about every 7-10 miles around here. I can get a new one with a lifetime warranty from advance auto for around $200 USD.
