Two choices: 1. Disconnect your battery for 1 minute. 2. Driver over to an autoparts store who lends out "code readers" and use that to erase the code. Number one is the easy since it requires no driving, but it will erase the station presets on your car radio. Number two allows you to erase and then pull any codes again, if they are there. It will read the old code and any newer ones, in this way, you will know if there is a new problem.
You need to test/replace the knock sensor. ireplaced it already.
The knock sensor has failed and you need to replace it with a new one in order for the check engine light to go out.
your knock sensor could need to be replaced
There's no need to replace knock sensors, and there was never a 3.6 engine.
A bad knock sensor would illuminate the check engine light and allow the engine to ping (spark knock). The engine doesn't shift, the transmission shifts.
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. The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine. The knock sensor generally threads into the engine block. This code may show up intermittently or the Service engine light may be lit constantly. You may notice drivability problems including a lack of power and perhaps some hesitation. There may also be other symptoms. * The knock sensor is faulty and needs to be replaced * There is a wiring short/fault in the knock sensor circuit * Check the resistance of the knock sensor (compare it to factory specs) * Check for broken/frayed wires leading to the sensor * Replace the knock sensor
Knock sensor needs to be replace
how many gaskets and which ones are needed when you replace the knock sensor on a Nissan frontier w/a 3.3l v6 engine?
There are 2 knock sensor on the 5.3L engine. And they are under the intake manifold. To get to them you will have to remove the whole top of the engine- INTAKE MANIFOLD. Why do you think they need replaced???? check engine light came on for 2 sensor
check the anti knock sensor on the side of the motor
If the knock sensor failed the CEL (Check Engine Light) would be illuminated and the engine may "ping" or "spark knock" under load. Serious "spark knock" can damage the engine if allowed to continue.
If a knock sensor was bad, the check engine light would be illuminated and the code(s) set would indicate so.
