P1400 INFINITI Tech Notes
Check electrical connector at the EGR solenoid valve and check for loose or clogged EGR solenoid valve hoses.Cost of diagnosing the P1400 INFINITI code
Labor: 1.0
The cost of diagnosing the P1400 INFINITI code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.When is the P1400 INFINITI code detected?
Malfunction is detected when the improper voltage signal is sent to Engine Control Module (ECM) through EGRC-solenoid valve.P1400 INFINITI Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1400 INFINITI Meaning
The EGRC-solenoid valve responds to signals from the Engine Control Module (ECM). When the ECM sends an ON (ground) signal, the coil in the solenoid valve is energized. The vacuum signal (from the intake manifold collector) passes through the solenoid valve. The signal then reaches the EGR valve.When the ECM sends an OFF signal, a plunger will then move to cut the vacuum signal.
