Where is the idle solenoid located? - Frontier Nissan Cars & Trucks

on throttle body

Sounds like it may be a faulty TCC clutch solenoid. Torque Converter Clutch. The TCC solenoid is located in the transmission valve body located directly under the transmission oil pan.

OPERATION

The Idle Air Control (IAC) valve adjusts the engine idle speed. The valve is located on the side of the throttle body. The valve is controlled by a duty cycle signal from the PCM and allows air to bypass the throttle plate in order to maintain the proper idle speed.
Do not attempt to clean the IAC valve. Carburetor tune-up cleaners or any type of solvent cleaners will damage the internal components of the valve.

TESTING

See Figure 1

Fig. Fig. 1: The IAC can be monitored with an appropriate and Data-stream capable scan tool

1. Turn the ignition switch to the OFF position.
2. Disconnect the wiring harness from the IAC valve.
3. Measure the resistance between the terminals of the valve.

Due to the diode in the solenoid, place the ohmmeter positive lead on the VPWR terminal and the negative lead on the ISC terminal.

1. Resistance should be 6-13 ohms.
2. If resistance is not within specification, the valve may be faulty.

REMOVAL & INSTALLATION

1. Disconnect the negative battery cable.
2. Detach the IAC solenoid connector.
3. Remove the 2 retaining bolts and remove the IAC solenoid and gasket from the throttle body.
4. Installation is the reverse of the removal procedure. Use a new gasket and tighten the retaining bolts to 71-97 inch lbs. (8-11 Nm).

If scraping is necessary to remove old gasket material, be careful not to damage the IAC solenoid or the throttle body gasket surfaces or drop material into the throttle body.
See Figure 2

Hello cody ayers19
The idle air control solenoid is located on the left side of the throttle body. Hope this is helpful.

Poster has not provided enough information to diagnose vehicle.What is the engine size?Have any repairs been attempted. Has engine computer been scanned for code or is check engine lamp on? Will engine run if throttle is held partially open? It is always necessary to perform a thorough visual inspection of all underhood components before performing any indepth diagnosis .Check all visible vacuum hoses and connectors for cracks or loose connections, check wiring connectors for same.Check large hose from throttle body to air cleaner box for looseness ,paying particular attention to clamps at mass air flow sensor.If no problem found on visual inspect.,locate idle control solenoid.It is on throttle body and has a 2- wire connector.lightly tap on solenoid body with a small soft hammer or medium screwdriver handle.If vehicle will now idle normally.remove solenoid and clean or replace(best to replace).TIP.An inexpensive engine stethoscope can be used to locate vacuum leaks at hard to see areas.listen for excessive hissing noise.

Hello Friend:

Sir Sounds like your Idle Stop Solenoid is Damaged or Your Throttle Position Sensor is Faulty.

Besure to Check the Connections to make sure you have no Corrosion or a Loose Connection.

Sounds more like the Idle Stop Solenoid than your Throttle position Sensor.

Go and Buy one there around $25-$35.00,In case your not sure of the Location it will help you identify the Idle Stop Solenoid on your Vehicle.

I hope this has Helped you and gets you running like it Should. Please let me Know how my Solution helped you by voting and a testamony. Thank You for using FixYa From: d_hubbs

OPERATION The Idle Air Control (IAC) valve controls the engine idle speed and dashpot functions. The valve is located on the throttle body on. This valve allows air to bypass the throttle plate. The amount of air is determined by the Powertrain Control Module (PCM) and controlled by a duty cycle signal. Fig. 1: Cleanable IAC valve — 5.0L engine version shown, others similar
Fig. 2: Non-cleanable IAC valve — 5.0L engine version shown, others similar
TESTING OBD-I System

1. Make sure the ignition key is OFF.
2. Disconnect the air control valve.
3. Use an ohmmeter to measure the resistance between the terminals of the valve solenoid. NOTE: Due to the diode in the solenoid, place the ohmmeter positive lead on the VPWR pin and the negative lead on the ISC pin.
   
4. If the resistance is not 7–13 ohms, replace the air control valve.

REMOVAL & INSTALLATION Fig. 1: Idle air control valve mounting — 4.9L engine version shown, others similar

1. Disconnect the negative battery cable.
2. Disconnect the engine wiring to the IAC sensor.
3. Remove the two retaining screws for the valve.
4. Remove the IAC valve and discard of the old gasket. Fig. 2: Disengage the idle air control solenoid electrical connection
   Fig. 3: Loosen the idle control solenoid retaining screws
   Fig. 4: Remove the idle air control solenoid from the throttle body
   To install:
   
5. Clean the area of old gasket material.
6. Using a new gasket, attach the IAC valve to the engine. Tighten the retaining screws to 71–102 inch lbs. (8–12 Nm).
7. Connect the IAC valve wiring to the unit.
8. Connect the negative battery cable.

Are you talking about the Idle Stop Switch? if so it is located on the carburetor, above the throttle linkage. If you are talking about the Idle Stop Solenoid then it is located on the right side of the carburetor near the throttle linkage.

If this helps please rate me.
