The Hewitt-Tech SAIS Pump Proxy Pack (PPP) is an Add-On to our popular SAIS Bypass Kits. Installing a Pump Proxy pack is a much less expensive repair than replacing a bad air pump and you can just leave the old faulty unit in place with no need to remove the intake manifold or get into the front fender. The pump proxy pack is only a proxy for the pump which will let the air injection driver/ECM think a good pump is connected which will let you clear a P0418/P0419 code that the bypass kit alone cannot. You must have a SAIS Bypass Kit Installed to use the PPP. A PPP can be added to the vehicle at the same time as long as a bypass kit is already installed.
Usually caused by an open circuit/damaged air pump motor. One pack is needed for each code.
