The Differential Pressure Feedback Exhaust Sensor, or DPFE sensor, is part of the vehicle's exhaust gas recirculation (EGR) system. The sensor monitors and measures the pressure with the EGR valve. This prevents the valve from malfunctioning and allowing too much exhaust into the intake manifold at one time.

You do not bypass the DPF Filter for daily use, you might consider bypassing for track and off-road performance applications, but in the long run, you do not want to bypass it, and I will explain why in detail in this article.

An air/fuel sensor can read a much wider and leaner range of fuel mixtures than a conventional O2 sensor. That's why they're also called “wideband” O2 sensors. Another difference is that A/F sensors don't produce a voltage signal that suddenly changes on either side of Lambda when the air/fuel goes rich or lean.

Nikon makes a DX-format sensor and an FX-format sensor. The DX-format is the smaller sensor at 24x16mm; the larger FX-format sensor measures 36x24mm which is approximately the same size as 35mm film. ... The FX sensor, with more "light gathering" area, offers higher sensitivity and, generally, lower noise.

The Sentro D gives the most accurate carbon monoxide readings possible in environments rich in diesel fumes which is used as an indicator of fire in some hazardous environments. ... The eModule is an intelligent standardised gas sensing module that detects carbon monoxide at levels of 0 to 50ppm.

To begin, the o2 sensors in your exhaust sense how complete the combustion in your engine is by reading the amount of oxygen gas. These sensors usually have 3 wires (power, ground, and signal). The sensor sends the signal back to the ECU telling it how much more fuel to send into the pump and through the injectors.

Our top pick is the Bosch Oxygen Sensor. This sensor will offer you a long service life that's free of contamination. It has a well-engineered design and is fast and efficient. Moreover, it's decently priced and works just as well if not better than higher-priced options.

Although MoT tests require diesel cars to have a DPF, this is checked via a visual inspection rather than emissions analysis. Removing the filter doesn't affect the car's performance, and some motorists even state they achieve better fuel economy and engine performance without one.

Locate the DPFE sensor. It is positioned to the left of the brake booster up against the firewall and has two metal tubes running from the EGR valve supply line and into the DPFE sensor. Note that some sensors will "float" above the tubes, while others may actually be fixed to the firewall by (2) bolts.

Sensor 1 is the upstream oxygen sensor. It is the sensor that measures the oxygen content in the exhaust, providing an input to the computer, which determines how to adjust the air/fuel ratio. Sensor 1 is the sensor closest to the engine. Sensor 2 is the downstream oxygen sensor.

Using Redex DPF Cleaner in every second or third tank will keep it working well. The soot burns away at high temperatures – so when you drive for a long time and a high speed your car can get hot enough to clear the filter. However, it's not a very reliable way to keep the DPF working.

The Ford Upfitter Switches are optional instrument panel mount switches (Option Code 66S) that control passenger side mounted relays. These relays power four blunt cut wires that are taped on a harness near the relay pack that can be found beneath the instrument panel and to the left of the steering column.

DPF filters go through a regeneration process which removes this soot and lowers the filter pressure. ... This fuel and exhaust gas mixture passes through the Diesel Oxidation Catalyst (DOC) creating temperatures high enough to burn off the accumulated soot.

A DPF delete removes a vehicle's DPF and configures the computer system to function without it. ... The exhaust is used to physically replace the DPF, while the tuner disables the vehicle's regeneration mode and ensures that no other engine codes come up.

You can clean rather than replace the expensive mass air flow sensor. Clean your MAF (Mass Air Flow) sensor when it's dirty rather than replace this $300 part. It's quick and easy with some handy tools and a spray.
