Verification Tests
TEST VER-1 VERIFICATION TEST- Reconnect and reassemble all components. NOTE: These vehicles use an air flow sensor. This makes it very important that all air intake hoses are in place and leak free.
- Start engine and let idle for one minute. Rev engine to 3000 RPM and let idle.
- To reset code 11 (Oxygen Sensor), or code 43 (EGR Temperature Sensor), the vehicle must be driven. Test drive the vehicle if any of these faults were previously stored.
- Read fault codes. If any codes are present, return to test DR-1A.
- If no faults are present, but vehicle driveability is poor, perform test DR-14A, No Fault Code testing.
