The coil in your application has a power wire (red), a ground wire (black), and a PCM pulse command wire (5 volt pulse; Blue w/Red stripe for cylinder No. 3) that operates the coil’s internal switching transistor. Using an oscilloscope,...

This is an electrical malfunction and is what is referred to as a "global" malfunction. That means a principal circuit, or circuits, was interrupted obviously on an intermittent basis. Battery terminal corrosion is possibly implicated at least as a contributing...

Hi Rick. Thanks for contacting us today. This Infiniti specific code can be related to other items besides the crankshaft position sensor itself. Some of the common sources include the Crankshaft Position Sensor harness is open or shorted, has a...

You will need to have the number one cylinder injector tested to see if it is getting signal from computer and cylinder compression to see if it has an internal engine problem. Then if these are okay then will need...

Hello. I will assume your drivers front window is not working. A mechanic can check the fuses for the window for any that may have blown. In the event of a blown fuses, some trouble in the circuit caused the...

Hello, With all those Warning Lights and the Check Engine Light on, the car needs to be connected to a scanner to see what faults are present. You will need the help of a mechanic with a scanner, such as...

The ignition coils do not have anything to do with the function of the transmission. The symptoms you describe suggest you may have a failing transmission control solenoid or a failing transmission control module. As you know, automatic transmissions use...

The only part you did not mention (and the most likely cause of the problem) is the inside lower control arm bushings (https://www.yourmechanic.com/article/how-long-do-trailing-arm-bushings-last_2) are bad. I would also check the steering gear mount bushings (https://www.yourmechanic.com/article/how-long-does-a-steering-rack-mounting-bushings-last) for excessive wear. Both of...

Hi. The electronic portion of your sunroof includes the sunroof switch, sunroof motor and body control module (BCM). The BCM supplies power to the sunroof motor when the operator pushes the switch. In some cases, a simple reset is all...

Hi There, Generally when the check engine light (https://www.yourmechanic.com/services/check-engine-light-is-on-inspection) is on, it will register a code in the computer indicating which oxygen sensor is bad. i would suggest starting with replacing oxygen sensors first as this is much more common...

When the brakes are released the distance that the piston moves when it retracts into the caliper bore is very small because it is necessary for the pads to remain in as close contact as possible with the rotors. The...

The code that you are referring to typically means there is an electrical problem in the crankshaft position sensor circuit. The issue is not necessarily the sensor itself and thus the output of the sensor must be viewed on a...

If you have the airbag light on then you may have a bad clockspring or airbag itself. Have the air bag system computer tested to see if this is the case and have a professional mechanic do any repairs since...

There are many causes of hard starting but illustrative ones are a faulty engine coolant temperature switch (sensor), malfunctioning idle air control (IAC) valve, vacuum and EGR leaks, inadequate fuel delivery or pressure (clogged fuel filter, dirty fuel injectors), and...

Does your car have a sun/moonroof? Sometimes the drain under the glass between the channels gets clogged with debris, if your lucky you can see it but if not have a certified mechanic track down the source of the leak....

Hello. The ABS and traction control / VSC fuses and relays would be the ones to check. There may just be one main ABS relay that powers all of the systems. U1000 and U1001 are codes indicating that a computer...

The only part you did not mention and the most likely cause of the problem is the inside lower control bushings which could possibly be bad. I would also check the steering gear mount bushings for excessive wear. Both of...

You're probably low on coolant. Filling the reservoir doesn't really do the trick for filling the cooling system. There is probably air trapped in the cooling system that needs to be bled out. You may be able to do it...

Check the inlet air tube between the mass airflow sensor and the throttle body for cracks or loose connections. When you put the vehicle in drive it pulls the hose longer and when it's put in reverse it pushes the...

Hi there. The rattling to grinding noise, upon start-up, with a/c on could be, the air conditioning compressor (https://www.yourmechanic.com/services/ac-compressor-replacement) developing a bearing problem. It could also be, the a/c compressor is fine and the serpentine drive belt tensioner assembly (https://www.yourmechanic.com/services/drive-belt-tensioner-replacement)...
