Where is the EGR pressure sensor located?

Where is the EGR pressure sensor located?

Mechanical EGR valve position sensors are mounted on the top of the EGR valve. EGR pressure sensors will be located close to the EGR valve as the exhaust gas hose must be connected to the sensor as well as the valve.

Does a 1999 Ford Ranger have an EGR valve?

99 Explorers all have EGR regardless of the engine option. However, a 99 Ranger 4.0L does not have an EGR system.

Where is the EGR valve located on a 1999 Ford Ranger?

Your EGR valve is located at the driver’s front of the engine, right up by the throttle body, which is under this plastic cover here. We’ll start by removing this nut on the EGR tube; this runs down to the exhaust to bring the exhaust gasses up and release them into the intake.

How is the dpfe sensor connected to the EGR valve?

On the way up to the EGR valve, the exhaust gas passes through a restriction. The DPFE sensor hoses are connected to ports 1 and 2—before and after the restriction. By comparing and reporting the differences in pressure, the computer can determine exactly how much exhaust gas is flowing through the EGR valve. Exhaust gas contains water vapor.

How does the EGR system work on a Ford?

Here’s how Ford EGR works When certain driving conditions are met and the computer wants exhaust gas recirculation, it provides a pulsing voltage to the electronic vacuum regulator (EVR). The EVR is a solenoid valve. When it opens, it allows intake manifold vacuum from port 5 to flow into port 6 on the top side of the EGR valve.

What does the ECT sensor on a Ford Ranger do?

– controls bypass air around the throttle plate at low speeds. – is controlled by the PCM. The ECT sensor (4.0L): – sends the PCM a signal indicating engine coolant temperature. – resistance decreases as coolant temperature increases.

What are the symptoms of a bad EGR valve?

Common Symptoms Of A BAD EGR Valve. The following are the most common symptoms that a Ford (or Mercury or Lincoln) car or truck will usually experience when there’s a fault in the EGR System: Car or truck runs fine, but the check engine light (CEL) is on with an EGR Valve Fault Code: P0401 EGR System Flow Insufficient.
