It turns on and off very quickly (called a duty cycle) to hold the EGR valve at a specified opening depending on the inputs to the control computer

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

Code p1400 on my nissan altima check engine light


P1400 - EGRC Solenoid Valve

The P1400 code is for the EGR solenoid and not for the valve. The solenoid control the opening and closing of the valve. You should check the solenoid hoses and the connector. Also check if there is voltage at the green/yellow wire.

Hope helps.

sounds like a problem in the egr valve or the porting through the egr valve or maybe a vaccuum line that has something to do with monitoring it. make sure there are no vacuum lines near it that are leaking and is there a difference in the idle that you may notice.

You need a charcoal canister and vent control valve.

You also need the EGR solenoid valve (I think it the brown one).

Valve is located in the valley of the V, towards the transmission side of engine.

Do these 1st and reset light. You may have other issues but you have to start here.
