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.

P0442: Have you inspected the lines, charcoal cannister etc? Make sure the fuel cap is tight. The easiest way to check the system is to have someone perform a smoke test. I had a DTC on my car which indicated a EVAP problem, it turned out to be the Fuel tank evaporator Control Solenoid.

SOURCE: tuoble code p 1444 purge control solenoid valve

The purge control is to allow the engine to **** gas vapors out of the charcoal canister that vents the gas tank. It will be in the engine compartment, and you should be able to see the canister as a cylinder about 4 inches in diameter and maybe 8 inches high. Follow the tubing to a valve that goes to the intake manifold. The valve should shut off at idle, but open at higher speeds. There is also a diagram in the engine compartment that shows where it is.

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):

zjlimited_50.png

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):

2008 duramax diesel has a p0080 engine code how do i fix it and where is the exhaust control solenoid located


code p0080 refers to exhaust valve control solenoid bank 1 --circuit high===causes--wiring short to positive--exhaust valve control solenoid --ECM

It is not an exhaust control solenoid but the exhaust VALVE solenoid that is causing concern. It is the solenoid that varies the timing of the exhaust cam and it is not doing that because it is faulty or there is a problem in the wiring. Contact a service dealer or find an accredited shop that specialises in your vehicle .

What code is po443


ossible causes
- Faulty Evaporative Emission (EVAP) Purge Solenoid Control
- Evaporative Emission (EVAP) Purge Solenoid Control harness is open or shorted
- Evaporative Emission (EVAP) Purge Solenoid Control circuit poor electrical connection
help.jpg What does this mean?
When is the code detected?
An improper voltage signal is sent to Engine Control Module (ECM) through the valve.
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P0443 Description
The Evaporative Emission System (EVAP) canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the Engine Control Module (ECM). The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.

Electronic pressure control solenoid circuit p1745. Check engine light on 2000 ford escort, 4cl, automatic. Advance auto told me it was a dealer part but I can't find it on any of the ford websites?...


Here is what the service manual says about the EPC solenoid, the processor looks at allot of different inputs to command the solenoids, such as Throttle Position Sensor, Vehicle Speed Sensors, Transmission Range Sensor and RPM signal, The PCM controls the shift patterns for the transmission. Electronic Pressure Control (EPC) Solenoid
The electronic pressure control (EPC) solenoid is located on the main control valve body and is controlled by the PCM. The EPC controls line pressure used to apply and release clutches and bands in the transmission.
The 2-3 shift solenoid is located on the main control valve body and is switched on and off by electrical signals from the PCM. The 2-3 shift solenoid activates the 2-3 shift valve which controls the automatic shifting between second and third gear. Second gear is established when the 2-3 shift solenoid is switched on. The 2-3 shift solenoid is switched off when vehicle speed increases and requires a second to third gear upshift.
The 3-4 shift solenoid is located on the main control valve body and is switched on and off by electrical signals from the PCM. The 3-4 shift solenoid activates the 3-4 shift valve which controls the automatic shifting between third and fourth gear. Third gear is established when the 3-4 solenoid is switched off. The 3-4 shift solenoid is switched on when vehicle speed increases and requires a third to fourth gear upshift.

Whats is Service Engine Code P1800 - VIAS Control Solenoid Valve Circuit Open


Here is the definition. Cost would depend on your area and the actual problem found after testing.

P1800 NISSAN Description When the engine is running at low or medium speed, the power valve is fully closed. Under this condition, the effective suction port length is equivalent to the total length of the intake manifold collector's suction port including the intake valve. This long suction port provides increased air intake which results in improved suction efficiency and higher torque generation.
The surge tank and one-way valve are provided. When engine is running at high speed, the Engine Control Module (ECM) sends the signal to the Variable Intake Air System (VIAS) control solenoid valve. This signal introduces the intake manifold vacuum into the power valve actuator and therefore opens the power valve to two suction passages together in the collector.
Under this condition, the effective port length is equivalent to the length of the suction port provided independently for each cylinder. This shortened port length results in enhanced engine output with reduced suction resistance under high speeds.

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.
