Mercury Capri EGR Valve Position Sensor
The Mercury Capri EGR Valve Position Sensor is a sensor that detects the angle of the EGR valve so the engine computer recycles just the right amount of exhaust. This reduces nitrogen oxides (NOx) without sacrificing power. In every Mercury model, the sensor attaches to the valve, which immediately sends a three-wire voltage signal the computer interprets. When the engine is at idle, the EGR Valve Position Sensor output is about 0.3 volts. After this, the voltage should smoothly rise past 4 volts as vacuum increases, proving the valve opens exactly with command. To check engine response, use a digital meter on the EGR Valve Position Sensor test. Touch the center wire, ground block, idle engine, then add vacuum with a hand pump and watch the voltage climb. If the voltage is erratic or drops to zero, this indicates that the EGR Valve Position Sensor has failed and may cause poor mileage, rough running, or a failed emissions inspection. During the Capri production run, Mercury only applied this electronic feedback type EGR Valve Position Sensor, so replacement units share the same three-wire design and voltage range. In just a few minutes, owners of a classic Capri can perform the check to avoid changing any parts unnecessarily. By guaranteeing the Mercury engine computer is always aware of the position of the valve, every Capri provides smooth combustion at all driving loads.

Mercury Capri EGR Valve Position Sensor Parts Questions & Experts Answers
- Q: What Are the Functions and Replacement Procedures for Coolant Temperature Sensor,EGR Valve Position Sensor,Intake Manifold Temperature Sensor,MAP Sensor,Mass Air Flow Sensor and Oxygen Sensors on Mercury Capri?A:All vehicles fitted with TFI-IV electronic ignition system also have the EEC-IV electronic engine control system, which contains an on board computer referred to as the Electronic Control Assembly (ECA) and other information sensors, which are responsible for monitoring the performance of the engine and feeding the data to the ECA. This data is processed in the ECA and output signals are produced to control intake and exhaust, emissions, fuel control, and driveability. The ECA is housed on the interior of the dashboard, and takes data feed from many sensors such as the Air Charge Temperature sensor, the Engine Coolant Temperature sensor, the Manifold Absolute Pressure sensor, etc which are key to flow of fuel and control of the ignition time. Systems influenced by the ECA are the A/C and cooling fan controller module, fuel injectors, and several solenoids controlling vacuum and fuel operations. The EEC-IV system also has self diagnosis feature whereby the trouble codes are stored in the PCM and can be retrieved for diagnostic purposes. Some of the procedures of changes of sensors including ACT, EVP, ECT, MAP, and EGO consist of the following steps; the first step is to disconnect the battery followed by the removal of the old sensor and replacement with a new one with proper sealing to avoid development of leakage. Putting back the mass air flow sensor which is found in the air intake duct involves some certain procedure that should be followed.
