Air injection pump bypass kits: Hewett vs. Rutech

@Bam1971 We may have already spoke on the phone or communicated through email but I wanted to follow up on the thread. As always thanks @shifty`

The first thing we need to do is some troubleshooting to verify what is causing the issue. That said can you please provide the following information;

• What error codes were you tripping Prior to installation of the Bypass Kit?
• Did you install the Block Off Plates that came with the Bypass Kit?
• Have you ever replaced the Air Switching Valves on the Vehicle?
  • Is so did you use factory/OEM or aftermarket components?
• Please send pictures of installation so we can verify that connections are correct

We see this combination of codes frequently in one of two scenarios. First, the pressure sensor has received damage and no longer reading within specification. This frequently happened when the valve stuck open there is potential for exhaust to leak in to the Air Switching Valve and damage the pressure sensor.

Second, this is common when aftermarket parts are used to repair the SAIS. If you replaced your Air Switching Valves with aftermarket components (Especially Bank #2 with the codes P2443 / P2447) there is a good chance you may need the addons as well. Our equipment is engineered to work with Factory/OEM equipment

Either of these scenarios would require the Pressure Sensor Addon.
