Where is the front brake solenoid valve located on a KIA Sorento?


That is part of the ABS system and it is on the modulator. The modulator is the block with all the brake lines connecting to it near the firewall on the drivers side under the hood.

How do i replace transmission modulator valve on a 1991 gmc sierra 1500 4.3


UNLESS you have a TH400 3 speed HD automatic transmission, which I HIGHLY doubt being it's a 1500 with a 4.3, you won't have a vacuum modulator. UNLESS someone swapped an older TH350 or TH400 transmission into the truck.

Instead you'll have what called a TV cable, or throttled valve cable.

This cable should be located on the passenger side of the transmission and is routed up to the side of the throttle body and hooked up like the old "kick down" cables.

The TV cable isn't simply a "kick down" cable, even though it does act like one, it also adjusts the pressure for the transmission to shift at different throttle positions. Much like the old vacuum modulators did.

Hope this helps.

Locate vacuum modulator chevy trailblazor 2003


Please verify the year of your truck. A 2003 Chevy Trailblazer has a 4L60E transmission. This transmission does not have a vacuum modulator valve. The 4L60 uses a vacuum modulator valve but the last year for that transmission was 1992. The perpose of the modulating valve is to control/regulate line pressure. The line pressure in a 4L60E is computer controlled or controlled electrically.

I NEED TO REMOVE THE EGR VALVE


The Exhaust Gas Recirculation valve does just what the name implies: it diverts some exhau st gases back into the intake system at low engine speeds. This lowers combustion temperature to reduce NOx levels. It also reduces throttle response and bottom-end power.
Disabling the EGR valve is easy. Locate the valve and the EGR vacuum modulator valve (two gold-colored metal stampings, usually at the rear of the engine). The EGR valve has steel lines leading to it from the exhaust manifold. The EGR vacuum modulator has two vacuum lines between it and the intake manifold and a third vacuum (soft) line between the modulator and the EGR valve itself.
EGR Vacuum Modulator
EGR valve (arrow) is shown adjacent tosimilar EGR vacuum modulator valve. EGR valve is connected to exhaust manifold with steel lines. Modulator has vacuum lines only.
Disconnect the vacuum line between the valve and modulator and place any solid object of appropriate size (dowel, etc.) in the line, then reconnect the line. Or you can get a EGR block off plate

{: ) The ABS/TCS module (or the Electronic Brake Control Module- EBCM ) is located at the front left lower corner of the engine compartment, under the air cleaner housing. The EBCM is attached to the brake pressure modulator valve. See sample diagram:

I need to change the transmission modulator valve on a 2003 Chevy Impala. I need help with the location of the valve and even steps on how to change it. Thanks


Hello, the 2003 impala's dont have a transmission modulator valve. this transmission is electronic controlled by the power train control module. the transmission uses a pressure control sol. inside the transmission instead of a vac. operated modulator valve. if you are having a late harsh shifting problem, this would be more in the area of a pressure control sol. at fault

It is located on the transmission with a vaccume line going to it. There is a clamp with a bolt that holds it to the transmission. It is an easy fix.
