Kit Addons

Our "Kit Addons" are used with one of our SAIS Bypass kits. Adding one of these products to the installation of the SAIS Bypass Kit will let the bypass kit take care of additional trouble codes. The types of codes the "Kit Addons" can take care of are generally those electrical fault type codes from shorted or open circuited components.
Even though the SAIS Bypass Kits prevent the SAIS from operating the computer or Air Injection Driver expect certain components to still be connected and within a certain spec. These kits addons will let you get around those fault type codes without also having to actually replace an expensive air switching valve or air pump motor.

A bypass kit MUST be installed to use any of these kit Addons. The factory wiring should be checked first to make sure it is not the source of the circuit fault.
Any cut, damaged or broken wires or connectors must be repaired before using most kit addons. Some kit addons may require proffesional installation or skill at safely identifying and altering factory wiring.

The Pressure Sensor Replacements can take care of these codes when added to a kit:

P2431 - Air Flow / Pressure Sensor Circuit Range / Performance Bank1
P2432 - Air Flow / Pressure Sensor Circuit Low Bank 1
P2433 - Air Flow / Pressure Sensor Circuit High Bank 1
P2436 - Air Flow / Pressure Sensor Circuit Range / Performance Bank 2
P2437 - Air Flow / Pressure Sensor Circuit Low Bank 2
P2438 - Air Flow / Pressure Sensor Circuit High Bank 2
P106B - Pressure Sensor Correlation / Evap. Pressure Sensor
There are different options depending on your vehicle's SAIS configuration and there may be more than one option for your vehicle. 

The Pump Proxy Packs can take care these codes when added to a kit:

P0418 - Relay 'A' Circuit Malfunction
P0419 - Relay 'B' Circuit Malfunction
Usually caused by an open circuit/damaged air pump motor. Not an actual pump replacement. One pack is needed for each code.

Codes the kits can take care of with the addition a Valve Solenoid Packs

P0412 - Switching Valve 'A' Circuit Malfunction
P0415 - Switching Valve 'B' Circuit Malfunction
Usually caused by an open circuit of the solenoid coil in one of the Air Switching Valves. A = Bank1 ASV Solenoid B = Bank2 ASV Solenoid. One pack is needed for each code.
