These Pressure Sensor Harnesses are a great cost saving addon to our bypass kits that will take care of problems caused a damaged pressure sensor. Comes in custom lengths depending on your vehicle's Air Swithing valve configuration, side by side or one on the top of each side of the engine.
On the 2007 and newer vehicles that have two air switching valves, it is fairly common for one of the air injection pressure sensors which are built into the air switching valves to become damaged from exposure to hot exhaust gasses. In these vehicles the air injection pressure sensors are much closer to the hot exhaust gases. Damage to one of these sensors can happen when the vehicle is operated with an air switching valve this is stuck open or leaking which lets the hot exhaust to reach the pressure sensors. It is more common for this sort of damage to cause the pressure sensor to read incorrectly without being damaged bad enough to cause a Pressure Sensor Circuit Code. This can cause valve stuck open codes even after installing the bypass kit and block off plates. It is also the most common cause of a P016B code which compares the two air injection system pressure sensors and the evap pressure sensor to determine barometric pressure.
Typically to fix a damaged pressure sensor you would have to replace one of the expensive air switching valve even after installing the bypass kit. This is still much less expensive than replacing the whole system but now you can just add a Pressure Sensor Harness to our bypass kit!
A bypass kit must be installed to use this harness and all the wiring for the pressure sensors must be intact. If you are getting a pressure sensor circuit code it is important to verify the wiring to the ECM is good first. Sometimes rodents like to chew on wires which the bypass kit nor this Pressure Sensor Harness can fix.
Typical Pressure Sensor Codes the Harness can take care of when added to a bypass kit. The valve stuck open codes which can also be the result of a damaged air pressure sensor are not listed here.
Detailed and illustrated Installation Instructions are easy to follow and include all details for each component of the Bypass Kit.
