Codes 1137 1138

Question

Is there a different name for the swire valve control valve solenoid valve when calling AutoZone or O'Reilly's because they don't seem to know what I'm talking about

Answer 1

P1137 Swirl control valve control position sensor

P1138 Swirl control valve

P1137 is the only code that needs to be resolved, P1138 is just following the code set for P1137.. Before you get involded to deep with this code check the charging system, if the alternator is not charging you set these codes, Beside not charging the Nissan has a tendency to over charge condition. You should not be no more than 14. 5 volts at idle. By the way you will not find a swirl control valve anywhere even in a salvage yard, it always stolen or missing
