How do I replace the Swirl Control Valve on a 2002 Infininty I35

Received the DTC P1800 and the dealer said to start with the Control Solenoid. However, I am having trouble identifiing the part.

SOURCE: Pls where is Swirl Control Solenoid Valve located in Infiniti QX4

This link shows the location of the SCV, If your motor is different the location should be similiar. http://img510.imageshack.us/img510/5687/vacuumdiagramuh3.jpg

There's a vaccuum line that runs off the SCV to the SCV check switch.

About DTC P1800, I suggest check the harness and verify it is plugged in and still functioning. Also, try checking your vac tubes to verify that they are not reversed. Also read this TSB with details about correct diagnostic: DTC P1800 VIAS CONTROL SOLENOID VALVE

The VIAS control solenoid valve cuts the intake manifold vacuum signal for power valve control. It responds to ON/OFF signals from the ECM. When the solenoid is off, the vacuum signal from the intake manifold is cut. When the ECM sends an ON signal the coil pulls the plunger downward and feeds the vacuum signal to the power valve actuator.

DTC detecting condition:
• An excessively low or high voltage signal is sent to ECM through the valve
Possible cause:
• Harness or connectors (The solenoid valve circuit is open or shorted.)
• VIAS control solenoid valve

Will need replaced the solenoid valve (P/N - 149558J10A). The valve is located under the engine cover. It's a Nissan only part so you have to order from the dealer, either online or in person. It's cheaper online. Check this sample Nissan engine location (click image for zoom)...

DTC P1147 - Bank1 Sensor 2 O2 sensor maximum voltage monitoring
Component Description: The heated oxygen sensor 2, after three way catalyst, monitors the oxygen level in the exhaust gas on each bank.

Even if switching characteristics of the heated oxygen sensor 1 are shifted, the air fuel ratio is controlled to stoichiometric, by the signal from the heated oxygen sensor 2.

This sensor is made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. Under normal conditions the heated oxygen sensor 2 is not used for engine control operation.

DTC detecting condition: The maximum voltage from the sensor is not reached to the specified voltage.

Possible cause:
Harness or connectors (The sensor circuit is open or shorted)
Heated oxygen sensor 2
Fuel pressure
Injectors

Majority of cases this is either a faulty O2 sensor, or short/open in wiring harness. Bank1 sensor2 is the rear O2 sensor on the passenger (right) hand side (click image for zoom):

Here is simple test with voltmeter to test O2 sensor. If it fails test, replace sensor. If not, then you will have to start tracing the wiring harness for a short/open in it (click for zoom):

Will code P1800 affect the engine running part on a 2004 nissan quest 3.5L what will it cause the engine to do what kind of driveable problem it cause?


Replace the" intake air control valve " to correct the P1800 problem. If not. You'll get poor performance which in turn cause more engine wear and tear. More fuel loss per miles. Computer will try to compensate. So engine works harder. Best to replace the part. From Nissan or amazon. Maybe eBay.

Hi i have 02 altima 3.5 v6 who have check engine light with code p1800 what is manufactured transmission control can anyone help me what that means?


You may want to have someone else take a look at it. The Nissan P1800 trouble code is not a transmission control problem. It is described as follows:

Trouble diagnosis name: VIAS control solenoid valve circuit.
Component Description:
The VIAS control solenoid valve cuts the intake manifold vacuum signal for power valve control. It responds to ON/OFF signals from the ECM. When the solenoid is off, the vacuum signal from the intake manifold is cut. When the ECM sends an ON signal the coil pulls the plunger downward and feeds the vacuum signal to the power valve actuator.
DTC detecting condition:
•An excessively low or high voltage signal is sent to ECM through the valve.
Possible cause:
•Harness or connectors (The solenoid valve circuit is open or shorted.)
•VIAS control solenoid valve

Check your vacuum hoses to make sure they are in good shape and are securely attached Aslo check the wiring harness is ok and securely attached as well. If they are, you’ll probably need to replace your VIAS. It's right next to the throttle body.
