Where is the crankshaft position sensor located on a 2001 Tahoe?

Answerif it is a 454 or an 8.1 L it is in the bottom of the timing cover by the crank pulley. You will need a 10mm socket to remove the sensor.

Where do you find the crankshaft position sensor on a 2001 Nissan Altima?

Locate the front wire on the distributer and follow. it will lead to the crankshaft position sensor.

Is it possible to bypass the camshaft positon sensor?

Not on a GM or a Chrysler

It can be unplugged to make sure the fuel pump is working(On a Jeep Cherokee). But for spark, "This sensor cannot be bypassed; that sensor tells the pcm when to fire the coil. "

Where is the crankshaft sensor located on your 2005 Nissan altima 2.5 engine?

I have a 2003 with the same motor and just replaced the sensor. It is located hear the top on the drivers side. Very easy to get to and replace.

What does a 1989 3.9L Dodge Dakota crank sensor look like?

A 1989 Dakota uses the distributor pick up plate for the crank signal. It is the plastic plate under the rotor inside the distributor cap.

What would happen if the crankshaft sensor goes out?

he vechiles computer system needs it to monitor spark and fuel delivery so if it goes bad you will think its out of time if the sencor is bad it might run poor then a no start at all will happen.

Where is crank position sensor on dodge srt10?

It's on the passenger side of the engine. About halfway down the motor just in front of where the motor mounts to the frame....you'll see a plug with a wires coming out of it. Mine had an aluminum foil type covering on the wires. Use a 7/16" deep socket to remove it.....you can't see it from the top of the engine, you have to crawl under the truck.....very simple install though.....good luck

How do you replace the crank position sensor on a 92 Olds Cierra 3.3L and can it be done with out pulling the harmonic balancer?

Can a camshaft position sensor cause car to stall?

it can, but i would check the ignition control module first....then the crank sensor.....

What is wrong with a 1993 Mercury Topaz that will crank but sometimes will not start for 15 minutes up to an hour and a half?

CHECK COIL LEAD FOR CONTINUITY The lead from the coil to the distributor has broken ,probably right at the coil end and the resultant arcing has gradually burned off the interior wire so that the spark to the distributor has to jump a longer and longer initial distance which then results in a hard start problem. Cut off the end boot, disassemble ,strip to expose new cable, BEND BACK ALONG CABLE; Dielectric,reassemble the connector and end boot.Its that easy! the rest below are unlikely solutions to a very simple problem. NO COST SOLUTION

Answerit sounds like your fuel cut off switch is not working right this also happenend to my car the question is where to find that switch they are usaully located inthe trunk of the car if you pull back the carpeting above the wheel wells you can locate them it well have a nice button on it that says reset some when putting things in the truck or move stuff around this switch gets bumped they usually wont tell you this because they like to replace the parts and charge a couple hundred dollars but this switch can get gummed up and shut on and off when cold car runs fine then when hot runs sluggish to stopping then will not restart until car has sat for awhile i replaced this switch and have not had problem since 5yrs ago or leads to right direction AnswerIf your fuel cut off switch is not the problem, then you will need to first check your plugs for proper wear, and spark. You will also need to have a quiet environment, turn your ignition on and listen for the fuel pump. My 93 Topaz GS I-4 has this problem (fuel pump not kicking in when the ignition is turned on). You could also have a clogged fuel filter (located on the passenger side fender under the hood), if the filter is clogged, it will restrict the fuel flow. Once the engine is turned off, the debris will gather in the filter element preventing proper fuel flow. Once the car has sat for a while, the debris falls to the bottom of the filter allowing fuel to pass. If the above does not fix the problem, then you may have a bad ignition control module (located on the side of the distributor). $85-$100 will get you an ignition control module, About $100 will get you a fuel pump, about $10 will get you a fuel filter, and about $5 will get you spark plugs. AnswerBe sure to check if you are burning fluids, if so than that is the same problem my 94 topaz has, it gets severe hydrolock when it sits for more than a day without being driven, the (incompressible) fluids collect in the cylinder and have to be burned out before the car is ok. Of course it is difficult to start the car with these fluids in the cylinders. AnswerIt might also be your starter which might not be running at full speed. This happened in my 92 Topaz and in a friend of mine with a 93 Topaz. Likely, if you bought the car used, the starter was probably not replaced recently. After wear and tear, they start to slow down to the point where it does not spin fast enough to start the car. I believe this to be an electrical problem within the stock starters. If this is the case, when you turn the key...it starts when it feels like it and you will hear ONE click if it does not. After a while, it won't start at all. This problem is easily cured, just remove the starter(right under the oil filter in the front) and have it rebuilt at a local auto electrical repair shop. Depending on where you go, expect it to cost between $60-$100 for the rebuild. This is just a thought if it applies to you.

Where is the Camshaft position sensor located on a 1991 Pontiac Bonneville SE?

I would suggest you go to www.autozone.com and enter your vehicle information under REPAIR INFO, VEHICLE REPAIR GUIDES, then select DRIVEABILITY AND EMISSIONS, then ELECTRONIC ENGINE CONTROLS. Select the control you are looking for and Autozone will tell you exactly where it is located and how to replace it. Hope you find this info helpful.

behind passenger side front wheel , have to take the pulley off..believe its the water pump pulley and the tire well off

Will a bad crank sensor cause a Hyundai Sonata to stall?

AnswerYes, but, if the sensor is permenately bad it probably wouldn't start again. It is , however, possible that it has an intermittent problem, causing it to stall, buck, or misfire. it could also have contamination on the flange (the part on the crank pulley), oil saturated wiring, or loose /shorting out wires. a visual inspection of under the timing cover will help.

If it stalls and restarts right away, check more into fuel pump problems and airflow monitoring systems, possibly even injector pulse (cam sensor related).

Where is the cam position sensor on a 1999 ranger 3.0 and is it 2 or 3 pin?

the cam position is where the distrubtor use to be in the back of the motor and depending on the year is weather it is a 3 pin or 2 pin

What is the crankshaft sensor?

A crankshaft sensor senses the engine revolutions to basically tells the the car when 2 inject and ignite the fuel

Do you need a tool to align crank sensor?

Yes. You use feeler gauge to set gap between sensor and crankshaft pully( .020 to .053)

How do you align the camshaft sensor without the synchronizing tool?

The only way is if you have not yet removed the old synchrozire. You can't if you have already removed the old synchronizer. There is no defined "clocking" point ,or way to aim the vane in the synchronizer, without that tool. There is no reference point. Now if you have not removed the old one, then you can observe where the vane is aimed. I ususally use a drop of white paint to mark the old one, then remove the synchronizer. I then mark the new one accordingly, and install it in such a way as to put it in the same place as the old one. If you have removed the old one, then you will absolutely have to get the tool to do it. But the tool is simple, and should be cheap, I would think, although have never priced it, since the shop I work in has all the alignment tools for us.

Where is the crank sensor on a 2000 golf 1.8t?

Where is the cam shaft position sensor?

AnswerIT'S UNDER THE POWER STEERING PUMP YOU HAVE TO REMOVE IT TO GET IT OUT.

Was able to replace the cam shaft sensor by removing the alternator,didnt have to remove the power steering pump.Used an extended mirrir to locate the sensor and removed it with a 1/4" drive 10mm long socket.NOTE: The alternator comes out by reoving 2 bolts, lay it off to the side and reach down and you can feel it. GOOD LUCK>

It could be on either end of the cylinder head, or in a distributor.
