I'd say the O2 sensor needs to be replaced

A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged.

I have a 95 Maxima that occasionally stalls when I come to a stop. The check engine light was on so I hooked it up to an OD2 sensor and it gave the following 7 codes: P 1320 - Distributor Signal...


Trying to clean the MAP sensor will damage it. Install a New Air filter and The Fuel filter, then replace the MAP sensor. Do not touch, or spray(compressed air or solvent) on the element when installing it. Have all of the OBD II Stored codes Deleted. Add a can of B&G 44K fuel additive to a full tank of fuel. The B&G is the best on the market, do not substitute. It is only available Through dealerships (Toyota). It will condition fuel pump and injectors. The ECU in your car is very dependable and rarely needs replacing. Always Replace cheapest parts first. Test drive the car and Then recheck The OBD II for new faults. The dimming of your lights before shut down was due to RPM of the engine dropping below 750 RPMs. Alternator will not produce voltage below 750 Rpms. 30 Amps at 14 Volts is required to run the engine.

1997 breeze is shooting codes 12 46 43 55


OBD Code 12 - No Distributor Reference Pulse (Diagnostic Test Active) The Engine Control Module-ECM uses the distributor reference pulse to calculate the engine speed. On newer engines, the Crank Shaft Position Sensor performs this function.

Symptoms:
  • When flashing the Check Engine Light to read codes, code 12 will always display first, indicating the diagnostic system is active
  • The engine will not run with a "hard" code 12 set
Common Problems:
  • Chances are you will never need to diagnose a code 12. Rather, the problem would be a crank, no-start condition.
  • If code 12 does not flash, that would indicate a communication problem with the ECM.
  • Code 12 does not show when reading codes with a scan tool. If there is a communication problem, the scan tool will let you know.



OBD Code 46 - Pass-Key II System Error - Circuit out of Frequency Range The ECM receives a signal from the Pass-Key module. When the correct signal is received, the ECM will allow the engine to start and run. Please review the RepairPal article on the GM Pass-Key Anti-theft systems for more information.

Symptoms:
  • Engine may not start
Common Problems:
  • Faulty ignition lock cylinder



OBD Code 43 - Knock Sensor error The ECM receives a signal from the Knock Sensor based on the amount of engine ping detected. The ECM uses information from this sensor to help calculate fuel delivery and spark timing.

Symptoms:
  • Engine ping
  • Lack of power
Common Problems:
  • Faulty Knock sensor
  • Poor connection at Knock sensor


OBD Code 55 - End Test.


Hope ehit help (remember comment and rated this).
