What should the EGR be on a diesel engine?
What should the EGR be on a diesel engine?
The accepted EGR static test is to measure the EGR position voltage at 0% (this is a KOEO test, BTW)and then command the valve to at least 99% duty cycle. Measure the EGR position voltage again. Closed, the EGR volts should be about 0.8 and wide open we typically see 3.8 to 4.0 volts.
What should I do if my EGR is not working?
Common EGR problems include: Pinging (spark knock or detonation) because the EGR system is not working, the exhaust port is plugged up with carbon, or the EGR valve has been disabled. The fix here is to inspect the EGR system, remove the EGR valve and check the valve and port for carbon, and remove the carbon from the port if it is plugged.
What’s the EGR value on my EBP sensor?
Last year when my EBP sensor was failing the scan tool would show EGR error of +99%; EGR command has never displayed anything but zero on my scan tool (because the scan tool incorrectly displays same!)
How does the EGR valve position sensor work?
The position sensor of the valve is linear and provides a signal proportional to its supply voltage (usually 5V). The EGR valve position sensor signal is set to increases in the direction of the opening of the valve. The position sensor is used for three main reasons:
Which is the correct formula for EGR error?
The EGR Error is also normalized for all types of EGR systems. The reading is based on a simple formula: (Actual EGR Position − Commanded EGR) ÷ Commanded EGR = EGR Error. For example, if the EGR valve is commanded open 10% and the EGR valve moves only 5% (5% − 10%) ÷ 10% = −50% error.

When does the EGR system take place in a car?
Actual EGR operation takes place during high load condition, cruising, and light acceleration. It is the job of various sensors and actuators to make sure that the EGR system works properly at all times. OBD II makes extensive diagnosis of the EGR system through the EGR monitor.
What should the EGR be on a F150?
The accepted EGR static test is to measure the EGR position voltage at 0% (this is a KOEO test, BTW)and then command the valve to at least 99% duty cycle. Measure the EGR position voltage again. Closed, the EGR volts should be about 0.8 and wide open we typically see 3.8 to 4.0 volts. 02 F150 with stuff on it.
What happens when the EGR error is + 99%?
I could actually watch the mass air flow drop a rather large amount when the EGR error was +99%; unfortunately when the engine is regurgitating that much exhaust back into the exhaust; the exhaust out the tailpipe really stinks……
Why does my EGR light not come on?
Not sure a light would come on with these trucks; I know I can unplug the EGR valve, set 3 codes (p0403, p0405, p0406) and the light will not come on. Then, he told me it may be getting a lean signal, I told him it is a diesel. Then he indicated sometimes the the O2 sensor will read lean or rich; even on a diesel.
What is the EGR valve on a 6.0 Powerstroke?
On the 6.0 Powerstroke engine, it is an extremely simple system consisting only of a cooler and a valve. When the engine’s computer decides the egr valve should open under certain conditions, the exhaust gas is let out of the cooler and into the intake manifold.

What makes the bostech egr501 EGR cooler fail?
The Bostech EGR501 EGR Cooler solves the common failure in your 2003-2004 Ford 6.0L Powerstroke. Most OEM coolers are failing due to cracking, which causes the water and exhaust to mix, or from becoming clogged with exhaust deposits. Bostech has developed a process making the cooler much more reliable and maintenance free.
