The Red warning light has started to come on the cars panel and stay on -

The check engine light or similar warning light is telling you a sensor has detected an abnormal condition, it is not a good idea to ignore this as the catalytic converters can be ruined in some cases.

Happens a lot. Always use the best high octane you can find. Check wire connections to knock sensor (most common cause for 'restricted performance light, sometimes outside temperature plays a part). Then disconnect negative terminal from battery, wait 2 minutes, reconnect. Then take car for a drive in various conditions, like city traffic, highway driving, and more. After several restarts, mine went away. Occasionally comes back, then disapiars. Ignore orange engine light.

Knocking noise

Mechanical wear on engine, incorrect valve timing, lack of oil.
Knock sensors are detecting engine knocking so sensors not at fault. Ignore fault codes and deal with the noise.

Warning light that looks like an engine

engine warning light . Comes on to tell you that the CPU has found some sensors that are failed . Check oil levels and coolant levels then run fault codes to find faulty sensors. Fix and do not ignore as it is there to protect the engine from failure.

Bad knock sensor symptoms

If your original engine didn't have a knock sensor, but the new one does, don't worry about it. You can safely remove it or just ignore it.

What causes a p 0327 diagnostic code on a 95 contour

P0327 - Knock Sensor 1 Circuit Low Input Bank 1 or Single Sensor
First check the knock sensor connector. If the connector is clean and secure, replacing the knock sensor usually takes care of the problem.

- An excessively low voltage from the sensor is sent to Powertrain Control Module (ECM) or Engine Control Module (ECM)

The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the Powertrain Control Module (PCM) or Engine Control Module (ECM).

- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power

Possible causes
- Knock sensor circuit short to GND.
- Knock sensor circuit short to PWR.
- Knock sensor circuit open.
- Damaged knock sensor.
- Faulty Powertrain Control Module (PCM) or Engine Control Module (ECM).

Test and check it. Hope helps.

Diagram location knock sensor quest 1998,I don't find the knock sensor on the nissan quest 1998

it is buried under the intake manifold. But ignore the knock sensor code, it means absolutely nothing. It will not resolve any issue you have. The KS code is usually the result of a broken engine mount.

go here if you have any issues.
