Gen 1 & Gen 2-3V: Pressure Sensor Replacement Wired Pigtail Only $25.00 We have the three pin connector/repair pigtail for the Pressure Sensor in stock. The two pin we do not.

The first thing anyone would need to know are what the codes are that it is throwing now. Limp mode is most often from "valve stuck open". The pump stuck off codes P2445 and/or P2447 are usually a failed air pump and don't typically cause limp mode by themselves. There is an 8 pin connector at...

I am not familiar with your current issues but you should not be going into limp mode with one of our kits installed. If it is SAIS please contact us directly via email or phone. support@hewitt-tech.com Toll Free 844-307-7671 We do not do any troubleshooting on forum threads since it is...

Sorry, currently no discounts on any of our Gen 2 kits. The GX470 uses the Gen2-3V which is a special version for most of the 4.7L vehicles. The Gen2 kit for the 200 is what we consider a standard type Gen2 kit that is completely plug and play. Aside from the differences in installation, the...

The Gen2 kit should have nothing to do with an O2 Sensor code. If this was a Gen2-3V kit where you have to wire the 3 wire whip of the harness directly into the ECM, you may have damaged another wire or possible wired into the wrong wires. Please contact us directly with pictures of your...

On any of the vehicles to get the system to show ready/complete you would need to use the Gen2 kits. On the 2005-2009 GX470 and LX470 vehicles you would be using a special version of the Gen2 kit, the Gen2-3V. The Gen2 kits need to connect into the system's pressure sensors. The problem with...

You can use ih8mud10 for 10% off a Gen1 kit. However, I would recommend the Gen2 kit for anything 2008 and newer instead of our current Gen1 kits. The Gen2 kit is simply a much better solution. Unfortunately, their cost to produce is continuing to increasing much more rapidly than the Gen1 kits...

Just happened across this thread. We have a variety of solutions for different years and code combinations. The Gen2 kit is certainly the recommended solution for any LX570. Just a quick gloss over, both Gen1 and Gen2 kits effectively stop the physical system components from operating, they...

The pump making the loud shop vac noise is usually the start of the failure on a 4.7l. Once that starts it usually progresses quickly to other codes but not always and can do it for a while. If you have codes we like to know what they are. Some codes with our Gen1 units need extra addons. Our...

When is the p2445 code and check engine light coming on? At startup or while driving. Take a look at the p2445 explanation on our codes page and see if it might be the freezing temperature glitch that is explained there. At startup you might not have the starter relay wire connected to the...

Glad to hear that and it sounds like you have it now. There are certainly a couple of things going on to consider why. First, going back and soldering the connections is the first thing we recommend. Soldering during the installation vs using the Scotchloks is highly recommended for this reason...

You should not be getting any pending codes after a reset. As far as the "readiness monitors" they cannot/will not show ready if there are any issues such as pending or active codes show up for the system in question. The normal way the Gen2 kit would work.. after clearing the active/pending...

Yes, you will need a good quality digital multi-meter/Ohm meter and an electrical diagram for connector, pin and wire identification. It is fairly straight forward usually. Basically you start by disconnecting the harness from both ends, the ECM and the transmission. Then one wire at a time (on...

None of our kits require intake manifold removal for any part of the installation. For a short time there we did offer a fully plug and play Gen2-3V that required removal of the intake manifold but no longer offer that version. Too many people were ordering them and were suprised that the intake...
