Where is the ECCS RELAY LOCATED ON 1999 NISSAN MAXIMAType your answer here...
IF ONE IS AVAILABLE ( JUNKYARD - 30 BUCKS ) I WOULD REPLACE THE PASSIVE BELT CONTROL BOX. LOCATED DIRECTLY UNDER THE ASH TRAY / BETWEEN SHIFTER AND ECCS BOX.
On the 1989-1990 240sx with the KA24E single overhead cam engine the E.C.C.S. is located on the top left side of the engine behind the throttle body and on top of the intake manifold.
Yes, most fuel injection engines can run on an E10 fuel..
On a 1995 Nissan Pickup, 2.4 liter engine, the crack angle sensor is located on the distributor under the distributor cap. It is regarded as the right hand to the ECCS control unit, as it is the basic signal sensor for the entire ECCS system. It monitors the engine speed, piston position and it sends signals to the ECCS control unit for control of the fuel injection, ignition timing, idle speed, fuel pump operation and the EGR functions.
Coolant Temperature Sensor/Switch (For Computer) ECCS Component Parts Location
This one is alittle tough to explain through text. Open the hood, now go to the passanger side of the car, see the silver intake plenum (says ECCS on it) on look all the way to the left, see the two hoses, look underneath them for a hole. through that holse is the screw, you will need a stubby screw driver to turn it.
Engine Computer Control System *- Also regarding Nissan 720 p/u Z24, ECCS can stand for Electronic Concentrated Control System ( I know 85's have this & 84 Calif. mod not sure what other years). System function is to control the fuel/air mixture at carb, it consists of following subsystems and components: spark plug switching control (switchs from 4-8 active plugs when needed), fuel shut off control (shuts off fuel during deceleration), fuel mixture heater (fitted under carb to heat fuel for better vaporization/burn), air fuel ratio control solenoid ( located in carb is the actual air/fuel mixer, different voltage inputs cause it to stay within certain values 14.7to1 I think!), O2 sensor, H2O temp sensor, throttle valve switch (located on side of carb sends throttle points to computer), vacuum switch on Int. manifold, clutch switch, neutral switch, inhibitor switch(A/T). On Z20 engines the ECCS incorporates a detonation sensor subsystem ( senses engine knock/ compensates). I've been unable to find a wiring diagram for insides of this control system nor any testing instructions, unit has one green light on side facing engine, I've yet to attempt checking it for any diag. codes (most of these units have a red and green light, however this year/model has only one green, will check it for slow/fast blink codes and update as needed. Sorry got carried away, toomuch info perhaps, but I like to be thorough.
Facing your engine from the front of your car, the alternator is on the mid left side below your ECCS/Throttle body/Intake. There are 2 bolts you will have to loosen. The first is the bolt on the FRONT side of your alternator tensioner. It takes a 12mm socket or wrench. This will free up the tensioning bolt that is located to the LEFT of the first bolt which you can unscrew to loosen your belt. I believe it also takes a 12mm socket. (I took off my intake tubing to get to it.)
This sensor is located on the front of the engine. I've had to replace this one before. It's a pain to get to because in order to access the sensor, you have to perform the same steps as you would to change the timing belt. If you look at the front of the engine, just under and to the vehicle's right of the distributor, you should see a wire leading to the sensor. You may or may not see the sensor itself because it's so badly buried. According to the Nissan Service Manual, the sensor, located on the front side of the driver's side cylinder head, detects cylinder head temperature depending on engine coolant temperature. The electric resistance of this sensor decreases in response to temprature rise. If the ECCS detects that this sensor is bad, it will set a Code No. 13 and set the Check Engine Light. My VG30 is in a 1989 hardbody.
Loss Of Offsite Power (LOOP). This results in load rejection by the turbine, and a trip and isolation of the reactor. Emergency Core Cooling System (ECCS) starts up, followed by the diesel generators, which brings the heatsink back. After a few minutes or seconds, offsite power is generally restored, and we stabilize and come back up with no problems. If its a short term transient LOOP - less than 10 seconds - the diesel generators won't generally even take the load. The word "crises" in this context is a misnomer - the plant is designed to handle a LOOP - its really a non problem - its more properly just called an event.
Diagnostic codes for 1989 to 1992 240 sx.to swith the modes - turn the ignition switch on. Turn the diagnostic mode selector located on the side of the ECU control unit 1 turn clockwise. The LED lamps will start to flash. Count the flashes until the number for the desired MODE is reached and then IMMEDIATELY turn the diagnostic mode selector located on the side of the ECU control unit 1 turn COUNTER clockwise. (if the mode selector is kept turned clockwise, the unit will continue to change in the order of MODE 1 , 2 , 3 etc.)ECU diagnostic memory will be LOST if the battery is disconnected OR if MODE 4 is selected after selecting MODE 3.Results are kept in memory until the starter is operated 50 times after an item is judged to be malfunctioning, at which time the result is cancelled. If the same item is judged to malfuncting again BEFORE the starter is used 50 times, it will be stored again and the memory will be stored until the starter has been used 50 times from that point.MODE 1 - During closed loop operation, green light is on when a lean condition is detected, and off when a rich condition is detected. (during open loop operation, red lamp stays off)MODE 2 - Green lamp function is the same as in MODE 1. During closed loop operation, the red lamp turns ON and OFF simultaneously with the green lamp when the mixture ratio is controlled within the specified values. (during open loop operation, red lamp stays off)MODE 3 - Red lamp flashes first and indicates units of 10. Green lamp indicates units of 1. (i.e.- 1 red 2 green =12)When engine fails to start, crank it 2 or more times BEFORE beginning self-diagnostic. DO NOT erase the stored memory, or intermittent malfunction information will be lost.code item Calif non calif11 Crank angls sensor output yes yes12 Air flow meter circuit yes yes13 Engine temperature sensor yes yes14 Veicle speed sensor yes yes21 Ignition signal missing in primary coil yes yes31 E.C.U.

Idle switch, starter switch - the on/off status of these switches as detected when MODE 4 is selected is stored in the ECU. When either swith is turned on to off or off to on, the RED led will come on or goes off each time switching is detected. Speed sensor - the on/off status of these switches as detected when MODE 4 is selected is stored in the ECU. When vehicle spped is 12 mph (20 km/h) or slower, the green LED on ECU is OFF. When speed exceeds 12 mph, green LED on ECU comes on.MODE 5 - Real time diagnosis - the moment a malfunction is detected, the display will be presented immediately by flashing the inspection lamps during a test drive. Compared to self diagnosis, real time is very sensitive and can detect malfunctions in a moment. ITEM REGARDED TO BE BE MALFUNCTIONS IN THIS MODE ARE NOT STORED IN THE ECU MEMORY. A malfunction is indicated if any of the following items is judged to be faulty: Crank angle sensor Ignition signal Air flow meter output signal Fuel pump (some models)Info as provided by CHILTONSJericho jayAnswer
