Knock sensor Lexus Rx300

Knock sensor their errors

Six months ago, I struggled with a sticky fourth gear on my RX for a long time. After much torment, the knock sensor (code 0330) turned out to be the culprit. The sensor was replaced, the problem disappeared, happiness, on the contrary, came.

Half a year has passed. The room turns off again. The code is the same, 0330. To put it mildly, surprised. Teachers too. They say that the knock sensor is generally an indestructible device, they have never seen it break in their life. And then 2 times in a row, finally.

1. Who is to blame and what to do? I don't like to change the sensor every half a year.

2. Can there be errors in the wiring of this sensor? Is it possible to buy the original cable with knock sensor connectors where it should be? Or something to shaman yourself? Is it possible to replace this wiring without disassembling the floor of the car (the sensor itself was changed for me for 3 hours, they say to disassemble a lot)?

Lexus rx300 Knock Sensor Symptoms You probably won't experience driving problems when a P0325 code is active, but that doesn't mean you can ignore it. Read below to find out how to diagnose and fix this knock sensor trouble code before it causes more problems.

Symptoms of a malfunction

The primary symptom of a P0330 code for the driver is the MIL (Malfunction Indicator Lamp). It is also called Check Engine or simply "check is on".

1. The control lamp "Check engine" will light up on the control panel (the code will be stored in memory as a malfunction).
2. The engine can run, but with reduced power (power drop).
3. Contractions, as well as detonation in the engine.
4. Higher fuel consumption.
5. There may be no other symptoms other than a stored DTC.

Code P0330 is not considered very serious. When it appears, it is unlikely that there will be serious problems with the controllability of the car, but a slight drop in engine power is possible.

• The knock sensor is defective and needs to be replaced.
• Malfunction or short circuit in the knock sensor circuit.
• incorrect fuel octane rating.
• Sometimes a bad PCM is the cause.

Troubleshooting code P0330: interpretation, causes, reset 12) Remove the upper radiator hose (located on the right, next to the "cruise" block). It must also be dry.

How to check

If a component breaks, the car will work as before. There may or may not be obvious signs of a malfunction. If a malfunction occurs, it will be considered electronic, since the device is part of the vehicle's electronics.

Device failure can occur for a variety of reasons, for example, due to a malfunction of the device itself, a short circuit in the system, or a break in the signal cable. To perform a self-test, you must determine where the sensor is located. The user manual has information on this.

It's best to check with a multimeter. There should be no kinks in your cables. It is better to use a device with short cables. The negative probe is connected to the sensor hole located in the center, and the positive probe is connected to the control connector. If the device is working, the multimeter indicator will show a surge of electricity at 40-150 mV.

If the device is faulty, there will be no activity. You can check from multiple devices; then there will be no doubt that the procedure was carried out correctly. After diagnosis, the faulty sensor is replaced.

How to Replace the Knock Sensor on a Lexus RX

• The weather outside is cold and the engine has started to overheat too quickly.
• Engine power is greatly reduced.
• There was a glow plug.
• The car began to accelerate much worse.
• Fuel began to be consumed in large quantities. Sometimes it seems that gasoline just evaporates.
• There was a lot more soot on the candles.
  
  Detonation increases significantly with increasing speed.

Knock sensor: what it is responsible for, what are the signs of a malfunction and how to check. What can I say, I haven’t received such acceleration dynamics from my Rex for a long time. But the dynamics are fundamentally different, they just tear to pieces. I thought it looked like it, I moved mine to the rear and realized that mine does not come after the "Japanese" at all. Having replaced the knock sensors with the Lexus rx300, the Japanese side had another drawback, which was the consumption, which remained in the region of 22 95 liters of gasoline per km.

The Check Engine issue affects many. Someone does not pay attention to this - “burn and let it burn itself”, someone is seriously worried about this malfunction.

Some technical centers do not have special diagnostic equipment and change everything at once. Sometimes they are lucky and they get over this malfunction, and sometimes they are not, and the problem remains.

In this article I will try to publish reviews on this problem from the car owners themselves, which, in my opinion, is very important and logical.

First of all, it is necessary to read the error codes and build the replacement logic based on them. You can first ask a question on our forums.

Now about the specific case when the knock sensor was faulty in the CHECK ENGINE on the Lexus RX 300.

P0325 PXNUMX Knock Sensor Circuit Malfunction

The knock sensor error code P0330 indicates a malfunction in the knock sensor circuit. That is, the PCM has detected a problem with the knock sensor or its circuit. Some vehicles may be equipped with more than one knock sensor. This code refers to sensor 2 on bank 2, the side of the engine that does not have cylinder #1.

I already joked with my friends on the topic “Yes, you unscrew this lamp and. It mounts well. At the weekend back to the workshop, and this time checking the second part of the wiring that goes from the connector to the ECU. I found 2 necessary wires on the chip of the engine control unit, hung a high beam ramp on them and applied 12 volts from the battery hood.

Burned for minutes after replacing the knock sensors on a lexus rx300 on each wire. While the lamp was on, I bent the wiring, trying to find the place of the break. The lamp never went out or flickered. So the wiring is ok.

There is only one culprit left, the ECU. But this is complete nonsense, I thought, how can I drive the control unit so that it does not see the sensor of the first head? He took out the block .. took it apart ... The board is whole, like new, there is no smell of burning, all the elements of the circuit from the sensor connection contact are intact, the ratings are the same.

I couldn’t find from which leg of the processor the signal comes from, since the board is 3-layer and the track goes to the middle layer, so the devil’s leg will break there. I gave it to the electricians, to no avail. Everyone says everything is fine.

How to check The RX's bumper is holding up well, and the only loosely related issue is the fog lights, which gradually get dusty inside and crack when they hit a puddle. Forcing puddles at a fast pace will cause your bumper mounts to crack a bit and the varnish will eventually peel off.

Replacing the abs sensor on the Lexus RX 300

History of technology

And the first generation Lexus RX, released in 1997, was the world's first luxury crossover. Later there was the BMW X5 and other MLs and Cayennes, but Lexus was the first. And the innovation has been well rewarded, with three successive generations of the RX topping its class in sales in the US, the class's largest market.

Nice touches on the RX II include Mark Levinson music, a reversing camera, adaptive headlights, TPMS (Tire Pressure Monitoring System) and even a Forward Collision Warning System, but no automatic braking. The car turned out not only comfortable, but also convenient.

Body

If ordinary Toyotas do not sin too often with corrosion, then Lexus should be obliged even more. In fact, better painting, careful study of all body elements and good car care have a better effect.

You can find a car with rotten arches, but almost certainly in his biography there were at least minor accidents with subsequent poor-quality restoration. Either the defects were extremely careless, after which they were poorly restored. The original paint may only be visible in a few places, and in the most extreme case you will only see light surface rust that is very easy to remove.

The edge of the rear arch of the body may have chips and swelling from the paint on the inside. You may also find "redness" on the underside of the window sill, where the paint wears off over time where the plastic lining contacts the window sill. Dirt often accumulates under the knees near the window sill, where a surface corrosion zone then forms.

Occasionally, rust spots appear on the windshield frame, hood, and leading edge of the roof. All other damages are not visible, they should be looked for at the bottom. As a rule, these are protruding staples, spot welds, fasteners and pendants. For hybrids, you can also check the cups of the front and rear suspension - these places break badly when used on our roads.
