If you want to delete the SAP and get no CEL error (Even passes Emission testing) build and install the SAP simulator in the knowledge base. The SAP simulator emulates the secondary air pump test completed by the DME then when the DME shuts off the SAP the emulator turns off which is a pass through mode.
SAP on the emulator removes actual O2 voltage and sends a 200mv voltage fooling the DME into thinking the SAP is working correctly.
With the SAP simulator I've not had a sap error in many years |
