Gen 1: Pressure Sensor Replacement Single


Low Inventory – Call for Availability

Pressure Sensor Replacement Single is to be used in place of air switching valves or damaged pressure sensors. These are used only with the Gen 1 Bypass kits and is not compatible with the Gen 2 Bypass Kits. Not a stand along product, must be used with Bypass Kit.

On 2007 or newer vehicles that have two solenoid type air switching valves with a pressure sensor (one in each air switching valve) this harness with a Factory Toyota pressure sensor is a great cost saving kit addon that will take care of problems caused by a damaged pressure sensors. This replacement sensor will take the place of the damaged pressure sensor built into your 5 pin air switching valve. In these vehicles, the air injection pressure sensors are much closer to the hot exhaust gases. Damage to these sensors can happen when the vehicle is operated with the air switching valves stuck open 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 as a valve stuck open code incorrectly instead of 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. Typically to fix the damaged pressure sensor you would have to replace the entire expensive air switching valve assembly. The Plug and Play version works with the 07-09 Tundra 4.0L, 4.7L, All 5.7L and all 2010 and newer vehicles including the 4.6L. It is only applicable to some 2007-2010 vehicles and all of the 2010 and newer except the 2.7L engine (sensor is available by itself for the 2.7L and a wired kit for the other 4.7L). A bypass kit must be installed to use this harness and all the wiring for the pressure sensors/ air switching valves 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. The PSR can also be customized by adding Valve Packs to the harness if needed to completely replace the air switching valve(s)! With Typical Pressure Sensor Codes, this 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.
