Where is the EGR valve on a Nissan Frontier?
The Exhaust Gas Recirculation (EGR) valve on a Nissan Frontier is a metal cylinder located at the back of the engine near the top. The EGR valve is responsible for taking the spent emissions and recycling them through the engine to be burnt a second time, limiting the exhaust fumes that are sent out of the tailpipe.
Where is the EGR valve on a carburetor?
The tube connects the upper part of the EGR to the carburetor. The valve’s metal disk contains a vacuum diaphragm, a plunger, and spring. Most have an electronic-vacuum EGR valve that is placed inside a cylinder or a small block.
Why is my EGR valve not working properly?
Chucks of carbon may also prevent the EGR valves from sitting as they should. The issue causes a rough idle, and in severe cases, the automobile might stall. This is because the exhaust gas does not re-circulate to the engine at idle, and it only happens when the motor exceeds the 30mph.
What can I use to clean an EGR valve?
This is a home experiment and an unbiased use of JLM Diesel Air Intake & EGR Cleaner. Similar products are available. This product is designed to dissolve carbon deposits, gum and varnish build up. It should restore air flow to the engine thus improving power and acceleration while reducing exhaust smoke.

Where is the negative battery cable on a Nissan Frontier?
Detach the negative battery cable of the Nissan Frontier from the battery post with an open-end wrench. Unscrew the nut at the top of the air cleaner on top of the engine with a socket wrench. Remove the air cleaner and filter from the top of the engine and set them aside.
How to diagnose an ECU 87-95 Pathfinder?
84 A/T Diagnosis Communication Line. 85 VTC Solenoid Valve Circuit. 86 Fuel Injection System Function right hand bank. 87 Canister Control Solenoid Valve Circuit. 91 Front Heated Oxygen Sensor Heater Circuit right hand bank. 94 TCC Solenoid Valve. 95 Crankshaft Position Sensor. 98 Engine Coolant Temperature Sensor.
Why does my Nissan Pathfinder have a check engine light?
Sometimes, they could smell oil odor and see dirty exhaust. If electrical parts are also affected and the Check Engine Light on your Pathfinder comes on, then the Pathfinder intake manifold, drive belt, rod bearing, valve cover gasket and throttle body gasket are the ones to blame. Second, suspension and transmission issues.
What are the sensors on a Pathfinder Pathfinder?
11 Crank Angle Sensor/Camshaft Position Sensor. 12 Air Flow Meter/Mass Air Flow Sensor. 13 Engine Coolant Temperature Sensor. 14 Vehicle Speed Sensor. 21 Ignition Signal. 22 Fuel Pump.
How is the dpfe sensor connected to the EGR valve?
Basically, follow the EGR pipe until you see 2 metal tubes next to each other split off from it, then follow those to the rubber hoses and those hoses to the DPFE sensor. The EGR Actuator is an electric device that allows small amounts of vacuum pressure to pass on to the EGR Valve.
Where is the EGR valve on my car?
There should be a box or a can looking container attached off the side, right by that part of the air intake. It will be held on by 2 nuts, a couple computer plugs, and a vacuum line. That’s your EGR valve. Thanks! How do I reset the engine light after changing the EGR valve?
84 A/T Diagnosis Communication Line. 85 VTC Solenoid Valve Circuit. 86 Fuel Injection System Function right hand bank. 87 Canister Control Solenoid Valve Circuit. 91 Front Heated Oxygen Sensor Heater Circuit right hand bank. 94 TCC Solenoid Valve. 95 Crankshaft Position Sensor. 98 Engine Coolant Temperature Sensor.
What should I do about carbon build up around the EGR valve?
If there is a lot of carbon build up around the EGR valve, you may also want to just save yourself some time and replace it with a new one. Clean out the entry port. The entry port is where the valve tubes connect to the engine (usually the intake manifold) while the EGR valve is off.
When to replace the PCV valve on a Nissan Frontier?
This automotive maintenance tutorial was specifically written to assist owners of the second generation “D40 Series” (2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015 & 2016) Nissan Frontier pickup truck with the VQ40DE 4.0 liter V6 engine in checking or changing the PCV (positive crankcase ventilation) valve.
Detach the negative battery cable of the Nissan Frontier from the battery post with an open-end wrench. Unscrew the nut at the top of the air cleaner on top of the engine with a socket wrench. Remove the air cleaner and filter from the top of the engine and set them aside.
