For example, if the red diode flashes once and then flashes twice rapidly this should be interpreted as code 12. With that said, I have seen people go through the relocation procedure and I haven't heard of any problems yet. Check the Knock Sensor Disconnect the connector from the knock sensor. Next, connect the red multimeter lead to the battery positive terminal and the black lead to ground. I did a web search on your problem and it was covered at several places. I been driving my 1999 Maxima for a year with those codes, as the cost to repair seemed high for my Maxima with 136,000 miles on it.
The codes are interpreted by the number of times and duration the diode flashes. You will see a plastic cover, pop the little screws out a … nd take the cover off. Recently I got a check engine light and the codes that popped up were P0300 P0325 and P0330. What you do is relocate the knock sensor to one of the plenum bolts. . If the plugs need replacing it's quite possible that the plug wires need replacing as well.
You might wanna check that and get it replaced soon. I had the knock sensor replaced recently. So, begin your diagnosis by visually inspecting the sensor and its connection. The knock sensor is a form of transducer, which is a device that converts changes in physical quantity into an electrical signal. I own a 99 Q45t, Ive had it for a year.
There will be a delay of 2. I checked everything visually, then started it up and looked at live-data. Start by consulting the wiring diagram for your vehicle from to determine which pin on the connector is power and which is ground. The signal tells the computer what the temp of incoming air is to help the computer decide how rich the fuel mixture should be. Replace the new one with a another new one and both cylinder ran good. Or are the bad knock sensors the cause of the P0300 misfire code? Repair Procedure for Nissan Knock Sensor Code Nissan uses the same knock sensor on the V-6 engines and the two varieties of four-cylinder engines mentioned here.
Unfortunately, it's a common occurrence for a Nissan knock sensor code to set on some of the automakers most popular engines and model automobiles.

This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time. Which gaskets will I need for the job? Many would like to ignore this code, but ultimately it can stop you from passing state inspection. Does anyone have a service manual or guide that may help me with this repair? The tps sensor has 2 potentiometers. If not, you have a problem with the sensor or its circuit. You should see a reading of about 12 volts indicating a good ground.
This is to verify whether the error code was caused by a failure in the mechanical system or not. If not, then you should find out why. If the P0420 code is combined with other codes, try fixing the other codes first. Replacing this same knock sensor part on the 3 L and 3. A knocking vibration from the cylinder block is sensed as vibrational pressure. Write the flashes down on a piece of paper especially if there are multiple codes.
. I think he scanned my truck and read the verbage related to my P1705 code mentions the word transmission. Allow the engine to warm up and aim the timing light toward the timing marks on the harmonic balancer. My transmission changes gears only after reaching the 40k rpms which is way high. If the sensor is working correctly, you should see the timing begin to retard. However, on the V-6 models you do have an option of relocating the sensor to avoid having to pull the engine apart.
Apr 19, 2014 P0303 is a misfire on cylinder 3 - check the ignition and injector on that cylinder. The only way to get at it is to remove the plenum and the intake manifold.
