P1400 INFINITI Possible Causes
- Faulty EGRC-solenoid valve
- EGRC-solenoid valve harness is open or shorted
- EGRC-solenoid valve electrical circuit poor connection
First diagnose P1400 INFINITI code
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals.
P1400 INFINITI Tech NotesCheck 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: 1.0The 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 MeaningThe 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.
