Honda ABS light LF Wheel Speed Sensor

Honda ABS light LF Wheel Speed Sensor

In this video we have a Honda Civic with an ABS light on I have stored codes for the left front wheel speed sensor. And a lot of cases it will set these codes falsely or will have premature ABS activation if there is rust build-up underneath where the sensor mounts into the Hub. Removing the ABS sensor and cleaning the rust from underneath the Hub and a lot of cases it could fix the ABS problem in your Honda. The ABS sensors are also interchangeable from side to side so you can swap them and see if the code goes to the other side. If it does the center will need to be replaced.

The ABS light is on comes on with a code 22-11 for the left front wheel speed sensor. If the light doesn’t come on it goes in to a false ABS activation when coming to a stop. The wheel bearing was noisy and was replaced and now it has this problem, didn’t have the problem prior to wheel bearing replacement.
Average Reported Mileage: 71461
Tests/Procedures: 1. This system uses a wheel speed sensor that produces a square wave signal that is sent back to the ABS control unit. Test the positive wire to the sensor for close to battery voltage. Test the wire labeled ground on the wire diagram for a square wave signal while the wheel is spinning. If there is no signal, verify the wheel bearing is installed properly. The wheel bearing has a magnetic encoder built in to it and the magnetic side (commonly the Brown side) needs to be towards the inside of the spindle. If the wheel bearing is installed backwards the sensor can not produce a signal.

  1. Inspect for damaged wiring or connections at that speed sensor.
  2. If the problem is not wheel bearing related and not caused by damaged wiring or poor connections, it is possible the wheel speed sensor may have been damaged during repairs. Try swapping this sensor with one of the other wheel speed sensors and see if the problem follows the sensor.

6.0L Ford Power Stroke Engine Misfire Diagnostic P0300

6.0L Ford Power Stroke Engine Misfire Diagnostic P0300
Working on a 2005 Ford F-350 Super Duty with a 6.0-liter diesel engine and we have a cylinder 7 misfire. The first thing we did is did a cylinder balance test to make sure that it was, in fact, the seven-cylinder that was in fact misfiring and it was.

Second, we made sure that injection pressure regulator was functioning properly at 85% when it was cranking. We also checked our injection pulse width. Cranking should be between .5 and 2.0 milliseconds. We also made sure the fuel injection control module Maine Power stayed above 45 volts when we were cranking the engine. Everything checked out good on the scan tool so we proceeded by doing a cylinder compression test. Providing that test about 350 PSI we’re going to go ahead and put a fuel injector in this vehicle.

Vehicle Application:
2004 F-250 Super Duty 6.0
2004 F-350 Super Duty 6.0
2004 F-450 Super Duty 6.0
2004 F-550 Super Duty 6.0
Customer Concern: The engine is very hard to start when cold and then runs rough or misfires almost until it reaches operating temperature. When it came in, it had misfire codes P0300, and P0301-P0307.
Average Reported Mileage: 151938
Tests/Procedures: 1. Verify the fuel pressure is 45-60 PSI when the truck is hard to start and running rough.

2. If the fuel pressure is OK, monitor the Injection Control Pressure (ICP) reading when cranking the engine. Compare the ICP reading to the ICP Desired (ICP DSD) reading. These should match when cranking. Also, the Injection Pressure Regulator (IPR) command should not go to 85%. If the ICP does not match the DSD and the Injection Pressure Regulator (IPR) goes to 85% when cranking, address the ICP system problem.

3. If the ICP and fuel pressure are OK, monitor the fuel pulse width when cranking. It should be roughly 0.5-2.0 ms (or 500-2000 us or microseconds).

4. If the fuel pressure, ICP, and fuel pulse width are all OK check compression on several cylinders to make sure it’s at least 350 PSI. If the compression is low, address the engine mechanical problem.

5. If all OK but there is little or no smoke when cranking and hard to start, suspect injectors that are not working as they should. If it has not been done, have the Fuel Injection Control Module (FICM) reflashed per TSBs 07-5-4, 09-7-11, and 09-24-3 and recheck operation. If the updates have been done, monitor the Fuel Injection Control Module Main Power (FICM_MPWR) reading when cranking. This should stay above 45 V. If it drops, check the powers and grounds to the FICM. If the powers and grounds are OK but the MPWR is dropping, suspect a faulty voltage converter in the FICM. Replace the FICM as needed and recheck operation. NOTE, if the FICM is replaced it will normally need to be programmed for the engine to start.

6. If the FICM MPWR is OK along with all other things mentioned above, suspect sticking fuel injectors.

Variable Valve Timing Code p0011 p0010 p0012 p0013 p0014 p0028 (Don’t Waste Money)

by

In this video, I’ll show you how to test a variable valve timing control solenoid. Commonly known to set timing codes p0011 p0010 p0012 and p0013.

There are a few things you should do before replacing a variable valve timing solenoid. Make sure the oil is full and in good condition. Is it a good idea it is a good idea to change the engine oil is this code has set just to be sure it’s not causing any problems

If changing the oil does not help with these codes I would recommend removing the variable valve timing control solenoid and cleaning it and checking on the screen for the breeze. Reinstall sensor clear codes and retest.

It is often unnecessary to replace the variable valve timing control solenoids. And typically VVT solenoids need to be cleaned. In the next video, I show you how to bench test and check a variable valve timing control solenoid.

Variable valve timing is very common in vehicles nowadays. So it’s important that you keep your engine oil changed regularly. To ensure that variable valve timing solenoids and actuators perform properly throughout the vehicle’s lifetime.

How Do I Reset My Maintenance 2014 Toyota Highlander

by

Reset My Maintenance Light!

Maintenance Light Reset, 2014, Toyota Highlander, oil light reset,14,

Turn the ignition switch to the On position, but do not start the engine.

Press the odometer button until you see ODO (for 2006-2012 models) or TRIP A (for 2013-2015 models)

Next, turn the ignition off.

Press and hold the Trip Reset button, and turn the ignition switch to the On position

If your car has START push-button, press the Start twice without touching the brake pedal.

Continue to hold down the Trip Reset button until “000000” MILES appears on the display and the maintenance light turns off.
Or the maintenance light in the smart display resets.

Toyota has one of the easy maintenance lights to reset.

pick nose, stand on head
pick nose, stand on head

Many of the car manufacturers nowadays you need to stand on your head, touch your nose and wiggle your feet. So with Toyota just having to hold the trip button in when you turn the key on is pretty easy. And the best part of it all is almost all Toyota use the same maintenance reset procedure. The only main difference is before shutting the key off, depending on what Toyota you have.  You need to set the odometer to either the main mileage, trip A, or trip B.

So if you have something other than a Toyota Highlander or a different year just try setting the trip on different setting then shutting the key off and holding the trip reset button as your turning the key one. Then continue to hold it down till all the “000000” countdown.
