Question 1

What are the instructions for replacing the engine coolant temperature sending unit on 1993-2011 Ford Ranger?

Accepted Answer

The dashboard gauge and the computer's fuel/air adjuster have different senders. The first one has a single wire while the latter has two or three. They are not placed in the same locations depending on the type of engine you have. For replacement, wait for the cooling system to cool off, open the pressure cap to release pressure, and then replace it. Disengage the electrical connector from the sender unit; uninstall it and promptly install another to minimize loss of coolant. Reattach electrical connection, inspect coolant level, and check if there is leakage when you start your car again.

How to replace the Brake Light Switch,Camshaft Position Sensor,Coolant Temperature Sensor,Crankshaft Position Sensor,Cylinder Head Temperature Sensor,Idle Control Valve,Intake Manifold Temperature Sensor,Mass Air Flow Sensor,Oxygen Sensors,Throttle Position Sensor and Vehicle Speed Sensor on 1993-2011 Ford Ranger?

Accepted Answer

To replace Engine Coolant Temperature (ECT) sensor for 2011 models, drain the cooling system, wrap new sensor's threads with Teflon sealing tape, unplug the electrical connector and remove the sensor by thermostat housing. For 2001 and newer 2.3L models a Cylinder Head Temperature (CHT) sensor is used; disconnect battery, expose electrical connector, unscrew and remove CHT sensor. The Oxygen Sensor replacement involves disconnecting the battery, raising the vehicle and removing the O2 sensor using proper tool, apply anti-seize compound to new threads and tighten it into place. Throttle Position Sensor (TPS) replacement requires disconnecting of battery, removal of throttle body cover, unfastening of TPS and ensure proper alignment during installation. Replacing Mass Airflow Sensor (MAF) means; firstly you need to disconnect battery from its terminal, then undo electrical connection between MAF sensor's plug-in connectors followed by taking off MAF sensor itself lastly install new one with a fresh gasket on 2011 models. To control air conditioning clutch relay PCM controls this while checking fuses for any malfunctioning Air conditioning clutch control means that PCM operates this clutch relay as you verify fuses for defects which may be interfering with idle speed quality in your vehicle at all times Vehicle Speed Sensor (VSS) change applies to those vehicles made before 1997; therefore when replacing it you are supposed to detach an electric connector from a particular component installed in a car under consideration while removing retaining bolt also do not forget about reversing above mentioned process Intake Manifold Temperature Sensor replacement includes disconnecting the battery, unplugging the intake manifold temperature sensor connector, removing the IMTS from intake manifold Idle Air Control (IAC) valve replacement requires disconnection of battery power supply followed by taking IAC valve cover out where electronic wires should be disconnected only after unscrewing screws Power steering pressure switch inspection comprises of checking fuses as well as circuits that might be affecting idle quality in your automobile Camshaft Position (CMP) sensor replacement varies with model, which may include but not limited to separating the battery, loosening electrical connector, removing sensor then fitting the new one properly. Crankshaft Position (CKP) sensor replacement includes disconnecting battery, removal of things like accessory drive belt or alternator, unscrewing of the sensor and installing new one with specific alignment procedures for different models Brake Light Switch or Brake Pedal Position (BPP) Sensor information informs about its purpose that is to show whether brakes are applied or not and it is located on brake pedal assembly.

Question 3

What are the instructions for replacing the engine coolant temperature sending unit on 2000-2011 Ford Ranger?

Accepted Answer

There are two engine coolant temperature senders. One drives the temperature gauge or warning light on the instrument panel; this is generally referred to as the sending unit. The other is used by the computer to determine engine coolant temperature and adjust fuel/air mixture accordingly; this is generally referred to as a sensor. The two are easily distinguished since the sending unit for the temperature gauge has only one wire going to it, while the unit that provides information to the computer has two or three wires. On SOHC four-cylinder engines, the sending unit for the gauge or light is threaded into the driver's side of the engine block, at the rear, just below the cylinder head. On 2001 and later 2.3L engines, the sending unit is located at the rear of the engine mounted into the coolant outlet pipe. Do not mistake the temperature sending unit for the oil pressure sending unit, which is just above the coolant temperature sending unit, threaded into the cylinder head. On V6 engines, the sending unit for the gauge is located on the front lower part of the intake manifold, near the thermostat housing. Allow the cooling system to completely cool down, then open the cooling system pressure cap to relieve any pressure in the cooling system. Install the cap. This will minimize coolant loss during this procedure. Disconnect the electrical connector from the sending unit. Wrap the threads of the new sending unit with Teflon tape. Remove the old sending unit from the engine. Place your finger over the hole in the engine to minimize coolant loss. Immediately install the new sending unit and tighten it securely. Connect the sending unit electrical connector. Check coolant level and top up if necessary. Start the engine and check for leaks.
