Diagnostic Procedures

Check for properly adjusted TP sensor before replacement of TP sensor. See SYSTEM/COMPONENT TESTS - 1.8L article. If DTCs 22, 24 and 31 are also set, problem is open in sensor ground circuit. An intermittent condition may be caused by poor connection, rubbed-through insulation, or a broken wire inside insulation. Check PCM harness connectors for backed-out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal-to-wire connections before component replacement.
