    No I need to know is the egr solenoid brown, green, or black?

  • dboyfire3 Aug 25, 2008

    Hey thanks for your help anyway I need to know how to test the egr solenoid to see if it's good

  • dboyfire3 Aug 25, 2008

    Hi I posted Pics of my engine and where I think my egr solenoid is located there's a green one, brown one and black one, but I don't know which one is the Egr solenoid. I have more pics upon request to view from farther out

  • dboyfire3 Aug 27, 2008

    Yes thanks it was the green one

Good dy;
As you are looking in the eng compartment from the front of the vehicle,look for the master cyl booster, the big round thing that is attached to the master cyl on the fire wall. now the EGR value will be just to the left of the booster. you should see three values there one on top the other two below, just like a triangle, the EGR is the bottom right value or the closet one to the boost. Hope this helps please let me know how you make out I'm trying to get a picture for you.

    Wow what color, ok what I get what you are saying is the location and color of the EGRC-solenoid valve? This solenoid is located almost right under the throttle cam on, the color got me on that one sorry could not tell you most one the ones I see are black. The EGRC-BRT is located at the back of the eng by fire wall. I hope this helps, sorry that I could not tell which color the solenoid is. Good luck.

    To test the EGRC solenoid.

    1. turn ignition off, Disconnect EGRC solenoid valve harness connector, Turn ignition on, using a voltmeter, measure voltage between EGRC solenoid valve harness connector terminal No. 2 (RED/YELLOW wire) and ground. If battery voltage does not exist, check for blown fuse No 17 or fault in RED/YELLOW wire. Replace or repair as required. If battery voltage exists, go to next step.


    Turn ignition off. Disconnect ECM harness connector. Using an ohmmeter, check continuity between EGRC solenoid valve harness connector terminal No 1 (BLUE?BLACK wire) and ECM harness connector terminal No 103. If no continuity exists, repair open in BLUE/BLACK wire. If continuity exists, go to next step.


    Apply battery voltage and ground to terminals No. 1 and 2. With battery voltage applied, air should pass between ports "A" and "B". Air should not pass between ports "A" and "C". With no voltage applied, air should pass between ports "A" and "C". Air should not pass between ports "A" and "B". Replace EGRC valve if airflow is not specified. If airflow is as specified, disconnect and reconnect harness connectors in the circuit and retest system.

    Hope this helps you to test the solenoid. Please let me know if this helps.

1997 Nissan alti ma threw code p1400. Cleaned she valve & checked she control solenoid harness. Replaced the egr control solenoid and it is still stalling at takeoff. Help please?

code p 1400 refers to exhaust gas recirculation (EGR) system or evaporative emission (EVAP)canister purge system===causes--wiring---EGR or EVAP valve or ECM
the valve in the EGR may be faulty and bot the solenoid or the problem could be in the EVAP side

Possible Causes
  • EGR/EVAP solenoid connector is damaged (check pins for damage, moisture)
  • EGR/EVAP solenoid control circuit open or shorted to ground
  • EGR/EVAP solenoid has failed
  • PCM has failed
Setting Conditions:
Engine running at Cruise speed under light engine load; and the PCM detected an unexpected voltage on the EGR/EVAP solenoid control circuit.

Were is the egr valve located on 95 maxium

It is a 1'1/8 " tall x1/2" w x1/2" D apparatus , brass body enclosing brown or green plastic with electronic receptacle in the bottom with 2 hose stacking on top ,one hose in bottom, mounted with one single bolt ,driver side , in front of the air intake next to the battery . It should say NISSAN K5T46583 then Mitsubishi sign then 6524

Looks something like this picture on this site.

97 Nissan Maxima OBDll code p1400. I replaced the egr valve the code still flips any suggestions would be greatly appreciated

The code p1400, is for an egrc solenoid valve, not the egr valve, they are 2 seperate items

exhaust-gas recirculation (EGR): An emissions-control system that reduces an engine's production of oxides of nitrogen by diluting the air/fuel mixture with exhaust gas so that peak combustion temperatures in the cylinders are lowered.

exhaust-gas recirculation valve (EGR valve): A valve, generally vacuum operated, to regulate the exhaust gas flow into the intake manifold.

EGR control solenoid (EGRC): receives ported and manifold vacuum, an EGR temperature sensor and a control backpressure transducer valve. THE operation of the system is controlled by the PCM which operates the EGRC solenoid. The manifold vacuum system utilizes a vacuum tap in the air intake system positioned after the throttle valve. The ported vacuum control system uses a vacuum tap in the throttle body which is exposed to an increasing percentage of manifold vacuum as the throttle valve is opened during acceleration. The backpressure transducer valve monitors the exhaust backpressure as the engine rpm increases or decreases to aid in controlling the amount of the EGR vacuum signal. The EGR temperature sensor is used to inform the PCM of temperature changes in the EGR passage way. This helps the PCM determine the EGR on/off time.

that should help on what they all do.

now by knowing all of that i highly doubt that the control solenoid could cause the problem, and if it was that then u probably have a PCM problem not the solenoid or both.P01400 generally means that the ECM is not seeing the correct voltage drop when it grounds the EGRC valve located between the banks of CLY'S near the top Radiator hose location the EGRC solenoid valve turns vacuum on to the EGR circuit or vents. With a OHM meter unplug the EGRC valve and measure resistance at the two pins. Most likely your car has a bad EGRC valve or a BAD wire to it from the engine control module. Valve Nissan Dealership would cost around $45 labor to diagnosis and replace $150. Make sure proper diagnosis is performed check the engine wiring harness with a stop lamp light bulb hooked to the EGRC connector to see if it lights up when driving. That way you know the circuit is ok. A engine harness with a open circuit is a bad surprise after spending $200 for the valve. Good Luck

Car dies when warmed up at idle and has to cool off before it stats

The EGR valve or EGR solenoid needs to be replaced
The valve will open if the engine gets warm although the solenoid does control that too. One is at fault

EGR Solenoid creates no vacuum

The EGR solenoid is located towards the rear of the car from the EGR vavle and slightly towards the center. It kind of stands on end. There is a vacuum line coming out the top (port C) and a green 2 wire connector plugged into it. Hope this helps.
