Test Description

WARNING: This page is about a different car, the 2002 Pontiac Firebird and 2002 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers in the diagnostic procedures.

  1. 2

    This step verifies that the malfunction is present.

  2. 4

    If DTC P1404 will only set during certain conditions, the malfunction may be intermittent. See DIAGNOSTIC AIDS . If an intermittent wiring condition is not present, test for a faulty connection at the PCM or at the EGR valve. If the connections are okay, and if DTC P1404 continues to set, replace the EGR valve. See appropriate REMOVAL, OVERHAUL & INSTALLATION article.
