The NISSAN Vehicle Immobilizer System will not allow the engine to start without the use of the registered key.
If the engine fails to start using a registered key (for example, when interference is caused by another registered key, an automated toll road device or automatic payment device on the key ring), restart the engine using the following procedure:
1. Leave the ignition switch in the ON position for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately 10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device (which may have caused the interference) separate from the registered key.
If the no start condition re-occurs, NISSAN recommends placing the registered key on a separate key ring to avoid interference from other devices.

Refrigerant pressure sensor
Description
The refrigerant pressure sensor is installed at the condenser of the air
conditioner system. The sensor uses an
electrostatic volume pressure transducer to convert refrigerant pressure to
voltage. The voltage signal is sent
to ECM, and ECM controls cooling fan system.
