A problem that Ford should take care in guarantee considering the poor quality of the sensor used and because it is a recurring problem on several vehicles. Ford recommends the replacement of this sensor, to do that, the complete dashboard removal is mandatory. The service costs around U$ 600 and the sensor around U$ 20. Therefore, it is not cheap.Material:- 1 37kOhm resistor (1/8 W);- Electric tape;- Stanley KnifeStep 1: Glove box disassemblyShow All ItemsDisassembly of the glove box pressing it on both sides.« Relays are either electromechanical relays or solid-state relays. In electromechanical relays (EMR), contacts are opened or closed by a magneticWith solid-state relays (SSR), there are no contacts and switching is totally electronic. The decision to use electromechanical or solid state relays depends on an application's electrical requirements, cost constraints and life expectancy.

have become very popular, electromechanical relays remain common. Many of the functions performed by heavy-duty equipment need the switching capabilities of electromechanical relays. air conditioning fan motor noiseSolid State Relays switche the current using non-moving electronic devices such as silicon controlled rectifiers.auto repair shops in tampa These differences in the two types of relays result in advantages and disadvantages with each system. indoor ac unit best buyBecause solid state relays do not have to either energize a coil or open contacts, less voltage is required to "turn" Solid State Relays on or off. Similarly, Solid State Relays turn on and turn off faster because there are no physical parts to move.

Although the absence of contacts and moving parts means that Solid State Relays are not subject to arcing and do not wear out, contacts on Electromechanical Relays can be replaced, whereas entire Solid State Relays must be replaced when any part becomes defective. Because of the construction of Solid State Relays, there is residual electrical resistance and/or current leakage whether switches are open and closed. The small voltage drops that are created are not usually a problem; however, Electromechanical Relays provide a cleaner ON or OFF condition because of the relatively large distance between contacts, which acts as a form of insulation. Although Solid State Relays accomplish the same results as Electromechanical Relays, the physical structure and functionality of Solid State Relays is different from that of Electromechanical Relays. Basic parts and functions of electromechanical relays include: Frame: Heavy-duty frame that contains and supports the parts of the relay.

Coil: Wire is wound around a metal core. The coil of wire causes an electromagnetic field. Armature: A relays moving part. The armature opens and closes the contacts. An attached spring returns the armature to its original position. Contacts: The conducting part of the switch that makes (closes) or breaks (opens) a circuit. Relays involve two circuits: the energizing circuit and the contact circuit. The coil is on the energizing side; and the relays contacts are on the contact side. When a relays coil is energized, current flow through the coil creates a magnetic field. Whether in a DC unit where the polarity is fixed, or in an AC unit where the polarity changes 120 times per second, the basic function remains the same: the magnetic coil attracts a ferrous plate, which is part of the armature. One end of the armature is attached to the metal frame, which is formed so that the armature can pivot, while the other end opens and closes the contacts. Contacts come in a number of different

configurations, depending on the number of Breaks, poles and Throws that make up the relay. For instance, relays might be described as Single-Pole, Single-Throw (SPST), or Double-Pole, Single-Throw (DPST). These terms will give an instant indication of the design and function of different types of relays. Break -This is the number of separate places or contacts that a switch uses to open or close a single electricalAll contacts are either single break or double break. A single break (SB) contact breaks an electrical circuit in one place, while a double break (DB) contact breaks it in two places. Single break contacts are normally used when switching lower power devices such as indicating lights. Double break contacts are used when switching high-power devices such as solenoids. Pole -This is the number of completely isolated circuits that relays can pass through a switch. (SP) can carry current through only one circuit at a time. A double-pole contact (DP) can carry current through two

The maximum number of poles is 12, depending upon a relays design. Throw -This is the number of closed contact positions per pole that are available on a switch. A switch with a throw contact can control only one circuit, while a double-throw contact can control two. General Purpose Relays are electromechanical switches, usually operated by a magnetic coil. operate with AC or DC current, at common voltages such as 12V, 24V, 48V, 120V and 230V, and they can control currents ranging from 2A-30A. These relays are economical, easy to replace and allow a wide range of switch configuration. Machine Control Relays are also operated by a magnetic coil. They are heavy-duty relays used to control starters and other industrial components. Although they are more expensive than general purpose relays, they are generally more durable. The biggest advantage of machine control relays over general purpose relays is the expandable functionality of Machine Control Relays by the adding of

A wide selection of accessories is available for machine control relays, including additional poles, convertible contacts, transient suppression of electrical noise, latching control and timing attachments. Reed Relays are a small, compact, fast operating switch design with one contact, which is NO. hermetically sealed in a glass envelope, which makes the contacts unaffected by contaminants, fumes or humidity, allows reliable switching, and gives contacts a higher life expectancy. The ends of the contact, which are often plated with gold or another low resistance material to increase conductivity, are drawn together and closed by a magnet. Reed relays are capable of switching industrial components such as solenoids, contactors and starter motors. Reed relays consists of two reeds. When a magnetic force is applied, such as an electromagnet or coil, it sets up a magnetic field in which the end of the reeds assume opposite polarity. When the magnetic field is strong enough, the attracting force of the opposite poles overcomes the stiffness of the reeds and draws

When the magnetic force is removed, the reeds spring back to their original, open position. These relays work very quickly because of the short distance between the reeds. Solid state relays consist of an input circuit, a control circuit and an output circuit. The Input Circuit is the portion of a relays frame to which the control component is connected. The input circuit performs the same function as the coil of electromechanical relays. The circuit is activated when a voltage higher than the relays specified Pickup Voltage is applied to the relays input. is deactivated when the voltage applied is less than the specified minimum Dropout voltage of the relay. The voltage range of 3 VDC to 32 VDC, commonly used with most solid-state relays, makes it useful for most electronic circuits. The Control Circuit is the part of the relay that determines when the output component is energized or de-energized. The control circuit functions as the coupling between the

input and output circuits. In electromechanical relays, the coil accomplishes this function. A relays Output Circuit is the portion of the relay that switches on the load and performs the same function as the mechanical contacts of electromechanical relays. relays, however, normally have only one output contact. Solid State Relays, like the one pictured above, are capable of switching high voltages up to 600 VACrms. are designed to switch various loads such as heating elements, motors, and transformers. Zero-Switching Relays - relays turns ON the load when the control (minimum operating) voltage is applied and the voltage of the load is close to zero. Zero-Switching relays turn OFF the load when the control voltage is removed and the current in the load is close to zero. Zero-Switching relays are the most widely used. Instant ON Relays - turns ON the load immediately when the pickup voltage is present. Instant ON Relays allow the load to be turned ON at any point in it's up and down wave.

Peak Switching Relays - turns ON the load when the control voltage is present, and the voltage of the load is at itsPeak Switching relays turn OFF when the control voltage is removed and the current in the load is close to zero. Analog Switching Relays - has an infinite number of possible output voltages within the relays rated range. switching relays have a built in synchronizing circuit that controls the amount of output voltage as a function of the inputThis allows a Ramp-Up function of time to be on the load. Analog Switching relays turn OFF when the control voltage is removed and current in the load is near zero. A relays useful life depends upon its contacts. Once contacts burn out, the relays contacts or the entire relay has to be replaced. Mechanical Life is the number of operations (openings and closings) a contact can perform without electrical current. life is relatively long, offering up to 1,000,000 operations. A relays Electrical life is the number of operations (openings and closings)
