Why do I need an EGR solenoid for my vacuum?
EGR solenoids are used to switch engine vacuum on and off at the right time. The time is based strictly on engine load and temperature. If the EGR circuit activates too soon, the engine will miss and run badly, or not at all.
How is the EGR system controlled by the computer?
The EGR system is controlled by the EGR control solenoid. When the EGR control solenoid is activated, a passage is opened up that allows exhaust gases into the intake manifold. The EGR solenoid is controlled by the engine computer, and activated at very specific times in order to achieve…
Is the Check Engine Light a sign of a bad solenoid?
An illuminated Check Engine Light is another symptom of a bad or failing EGR control solenoid. If the computer detects an issue with the EGR solenoid, circuit, or system, it will set off the Check Engine Light to notify the driver of the issue.
What kind of fuse to use on EGR solenoid?
Make a jumper wire with an in-line fuse holder and install a 10-amp fuse. Crimp each end of the fuse holder to a section of wire using crimp connectors. Make another jumper wire and attach both wires to the connectors on the solenoid.
How does a solenoid work on an EGR valve?
Blow through the vacuum hose. Air should pass through when it is energized. This test determines whether the valve is opening when it is energized, allowing unrestricted flow of vacuum. If the solenoid fails any of these tests, replace it. Some solenoids were designed to modulate the vacuum to the EGR valve.
What is the voltage of an EGR valve?
With the valve closed a voltage of 0.7 Volts was present on the signal wire and with the valve fully open a voltage of 3.5 Volts was present on the signal wire. This proved the EGR valve was working as expected. The next step in the diagnosis was to actuate the EGR valve while monitoring the output from the MAP sensor.

Where is the Check Engine light on a Honda?
Turn the key into the “off” position if either of these occurs. Figure 1. A steady check engine light. (Related Article: Warning Lights – Honda-Tech.com) In the passenger’s side foot well, remove the kick panel by the side door. This will allow you access to the Engine Control Unit (ECU) and jumper plug (service connector).
Where is the EGR valve on a Honda Jazz?
On the Jazz is a connector to the EGR, (easy to locate, a black cylinder to the left) if you unplug it it will run smooth again but you will sacrifice fuel efficiency around 36mpg. showing on my dash. if you plug it in again the kangaroo will jump back again.

What are the symptoms of a faulty VVT solenoid?
Common signs of a faulty VVT solenoid include the Check Engine Light coming on, dirty engine oil, rough engine idle, and decreased fuel economy. 1. Check Engine Light comes on 2. Engine oil is dirty 3. Rough engine idle 4. Decrease in fuel economy
What’s the diagnostic code for the EGR valve?
Several technical service bulletins for a wide variety of different makes and models have documented different problems associated with the EGR valve system. With some exhaust gas issues you might set a diagnostic trouble code of PO401 or P0402.
What should I do if my EGR light is not working?
The repair of this condition is removal of the EGR valve and inspection of the passageway to check for a blockage. Each model vehicle has different procedures for clearing the passageway due to many different configurations of the system. Some Fords have a removable tube.
