Clutch replaced on my 2002 Acura RSX type S. Engine light . codes::Left front wheel speed sensor; Rear right outlet Solenoid sensor mlf:;Low Voltage Knock Sensor.Engine turnover probs afterrefueling


left front wheel speed sensor is more then likely due, to a malfunction sensor for the abs sensor, badly connected sensor, or wiring, or contacts corroded or damaged, the knock sensor is usualy do to a fault sensor at the crank shaft where the timing belt is due, this is also more then likely to your engine turnover problems and is just coincidence when refueiling

I have a 2005 New Jetta 2.5 and I am trying to locate the knock sensor location


A knock sensor is often located bolted on the center of the wall of the cylinder block Find the electric harness above the thermostat (usually located near the area where the radiator hoses meet the engine). It is usually a gray/black connector with two wires and a red cap.

2. Unplug this connector and fix a voltmeter that can measure more than 10 M ohms to the male connector.

3. Check the foremost terminal and ground the negative point out.

4. Check the voltmeter for continuity after turning the vehicle on. If there is a problem with this, you will need to replace the knock sensor.

5. Also, if your vehicle has run over 100,000 miles without replacing the knock sensor, it is best to get it changed.

6. You will also need to check for frayed wires to confirm a faulty sensor.

7. Another way to test the knock sensor is by striking the intake manifold above the knock sensor with a wrench, while the engine is running. Be careful not to strike the sensor. Hitting the intake manifold should result in a small change in the sound of the engine. If this does not occur your knock sensor is probably dead.

I have a 99 oldsmobile bravada 4.3 jasper engine new with 61k and the service engine soon light came on and read a po327 knock sensor code Please tell me how to fix it and where its located on the engine


Hi, this code could indicate a wiring issue or a problem with the sensor itself. A new sensor is about $40. The sensor is on the back of the engine as shown in the picture below. If you have an ohmmeter, I recommend you check the continuity of the wire from the sensor to the computer. The computer is in the passenger side door pillar. Locate connector B, pin 19. You do not need to disconnect the computer to check continuity of the wire. Just probe the back of the connector at the dark blue wire, pull the connector off the sensor, and touch your other ohmmeter probe to the terminal in the knock sensor connector. There should be one ohm or less resistance in the wire. If resistance is higher than one ohm, repair or replace the wire. If resistance is good, unscrew and replace the sensor. Please let me know if you have questions, and thanks for using FixYa.

I HAVE A CHEVROLET 2001 TAHOE AND HAVE NOT HAD ANY PROBLEMS WITH THE ABS IN THE LAST FIVE YEARS OF OWNING THIS VEHICLE. HAD A ABS MODULE PROBLEM SO HAD IT REBUILD. AFTER REBUILD I STARTED HAVING...


Hello,
There is a ground wire connected to the engine block. Look for it on the back passenger side of the engine towards the top. Remove it and clean the connection and the wire connector and replace. Sometimes they get real bad and throw the ABS light on. Sometimes a brake light out can throw the ABS light on.

  • You said you rebuilt the ABS module, do you have a short in it you are missing? The bulletin for this originally suggested to replace the module and was corrected because the ground itself was the major offender.
  • Try to reground the EBCM. The code 0265 says "loss of communication with the brake module" The EBCM Ground is located on the frame beneath the driver's side door. If multiple grounds are found in this location, the EBCM ground can be identified as the heavy (12-gauge) wire. Clean the area, front and back, using a Whiz Wheel.

  • Install the ground, then the washer and then the bolt to the frame. Important: It is important to use the bolts, washers and nuts specified in this bulletin. These parts have been identified due to their conductive finish.
  • Install a washer and nut to the back side of the frame.
  • Tighten the nut to 9 N·m (79 lb in).
  • Cover the front and back side of the repair area using Rubberized Undercoating. An additional check can be made to ensure a good connection for the Battery Cable to Frame ground.

1989 K1500 GETTING CODE 43 NEW ENGINE REPLACED KNOCK SENSOR AND THE CONTROL MODULE.


The 43 is the knock sensor, the wires must be broken or fused together to continue to get the same code.
Testing the sensor for the DIY Knock sensors detect detonation ( knocking ) by reacting to the ping by retarding the ignition timing so you will need a timing light for this. connect the timing light and locate the knock sensor, ( many are on the intake manifold ) now use a metal object to tap ( not too hard and not on the sensor itself ) on the intake manifold ( light tapping should suffice ), if the sensor is functioning you will see the timing ******. If the timing does not ****** you will need to check voltage across the terminals of the knock sensor connector.
Though that excerpt says your sensor is in the intake,I believe yours is in the water drain hole for the engine block.
I also found that most shops are to replace the wire to the knock sensor because of so much failure of those wires because of heat.
Enough information?Repost if this doesn't help and we can look at some other things to try.

Engine light and ABS traction control light remain


The ABS sensor is a speed sensor also for Traction Control. This is why both lights are on , One of your front ABS sensors are bad or disconnected, or has a pinched wire.

Check engine light tells me knock sensor or circut ecu


On a 6 cylinder, the knock sensor is located under the intake manifold, on the inside edge of the cylinder block. You must remove the entire intake manifold assembly to access the knock sensor. If you are replacing it, it would be very advisable to replace the sensor AND the extension wire from it to the main harness. I have observed that the wire extensions become brittle over time, and they fail with regularity.

Nissan xterra knock sensor


It's the valley of the engine underneath the intake manifold. It's about an $800 job because the top of the engine has to come off. However, unless you have a supercharged xterra it shouldn't effect performance. Also, the knock sensor will not trip the check engine light, as it does not indicate a primary problem, so if your light is on you should have another code that should be fixed first.
