P1400 NISSAN Possible Causes
- Faulty EGRC-solenoid valve
- EGRC-solenoid valve harness is open or shorted
- EGRC-solenoid valve electrical circuit poor connection
How do I fix code P1400 NISSAN?
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 connector’s pins.
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 NISSAN code
The cost of diagnosing the P1400 NISSAN code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected
Malfunction is detected when the improper voltage signal is sent to Engine Control Module (ECM) through EGRC-solenoid valve.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1400 NISSAN Description
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.
