Crankshaft Sensors
In an internal combustion engine, a crankshaft sensor is a component used to monitor the rotational speed and position of the crankshaft. The information provided by the sensor is used by the engine control unit to manipulate ignition system timing.

Where is crank sensor on 97 Chevy astro van 4.3?
The crank position sensor On your astro is located
on front of the engine on timing cover, left side.
Behind the crankshaft pulley. with a connector of 3 wires.
How often should you change crank sensor?
You only need to change it if it has failed. There is no other reason.
The crankshaft SENSOR shouldn't be much trouble. It's location depends on the manufacturer and the engine type. Check in one of the manuals that cover your car, like Haynes or Chilton and it shoud give you reasonably accurate information on the location of the crankshaft sensor. If you need to replace the crankshaft, first, remove the engine... Yes, it can be a pain but the biggest piece of machinery you will need is an engine lift.
Does the starter have to be removed on a 93 Saturn 1.9 ltr sohc to replace the crankshaft sensor?
NO you can replace it without I't's just a 10 mm head bolt but you will need pliers or a screwdriver to "help" the sensor out The "O" ring will be tight

1999 Saturn SC2 error code P0341 camshaft position sensor a - bank 1?
P0340/P0341 Troubleshooting S-Series ----
Most of this came from TSB 98-T-49A, with a few of tips thrown in.
Both P0340 and P0341 both relate to the Camshaft Position Sensor (Let's just call it Cam Sensor from now on), the only problem is that the S-Series engines don't have a Cam Sensor, not a typical one at least. Instead, the DIS module watches when the #4 spark plug fires on the compression cycle and fakes a Cam sensor signal from it. The tricky part is that on a DIS waste spark system, spark plugs fire with their mated cylinders(1/4 and 2/3 in 4 cylinder engines) every time the cylinder is at TDC, regardless of whether the cylinder is on exhaust or compression. However, it takes far more voltage to fire a spark plug on the compression stroke then on the exhaust stroke, due to the compressed air (the more air molecules, the more air the spark needs to jump, hence more resistance to spark). The increased voltage needed on the compression stroke is detected by the "#4 sensing circuit" inside the DIS module for the Cam Sensor signal. If the resistance of the secondary system is not in the proper range or something else is affecting the voltage draw, the "#4 sensing circuit" will be unable to work properly.
In short, anything wrong with the ignition system and you have a bad Cam Sensor signal.
Next for the diagnostics, I'm converting this from a graphic map to a text format, so bear with me...
Step 1: remove secondary wires from spark plugs; keep the wires on the coil. Measure resistance from #1 wire to #4 wire and then #2 wire to #3 wire. Resistance should be 11k ohms to 45k ohms(YIKES that's a wide range)
If resistance is in spec, go to step 2, if not in specs, go to step 3
Step 2: remove secondary wires from the coil packs and check for corrosion on the towers and wires.
If there is corrosion, go to step 4
if not, go to step 5
Step 3: remove secondary wires from the coil packs and check for corrosion on the towers and wires.
If there is corrosion, go to step 4
if not, go to step 6
Step 4: Replace or clean coils and/or wires as necessary. Retest to confirm.
Step 5: Remove spark plugs. Check for carbon or abnormal wear and proper gap (0.040 in)
If plugs check out good, go to step 8.
If the plugs are bad, replace as needed and retest to confirm.
Step 6: Measure resistance of individual secondary wires. specs are 1.5k ohms to 15k ohms (that's what this chart says, but my knowledge says 8k ohms is normal, greater than 12k ohms should be replaced)
If wires are in spec, go to step 7
If wires are bad, replace as needed and retest to confirm
Step 7: Measure resistance from tower to tower on the coil packs (hold tight for good reading). Spec is 8K to 15K.
If coils are in spec, go back up to step 5
If coils are bad, replace as needed and retest to confirm
Step 8:(90% of the time I'll bet the problem is solved by now) Start engine. Perform under hood visual inspection of the ignition system, check for arcing (best done in a dark area, if you are inside a garage, be sure the exhaust is vented). Wet DIS module, coils, and secondary wires with salt water to provide optional ground path (arcing from the wire boot to the valve cover is possible, but would be hidden)
If arcing is present, replace wires or coils as needed and retest to confirm.
If not, go to step 9.
Step 9: Turn ignition off, back probe J3D03 (Circuit 633, brn/wht wire) at PCM with voltmeter. Connect other lead to ground. Turn ignition on, engine off and measure voltage.
less then 4.5 volts, go to step 10
4.5-5.5 volts, go to step 12
more then 5.5 volts, go to step 11
Step 10. Check connections in circuit 633, repair short to ground, retest to confirm
Step 11. Repair short to voltage in circuit 633, retest to confirm.
Step 12. Start engine, and observe voltmeter at idle
less then 2.0 volts, replace DIS module, retest to confirm
2.0 - 4.0 volts, problem intermittent
4.0 - 5.5 volts, go to step 13
more then 5.5 volts, go back up to step 11
Step 13. Turn ignition on, back probe circuit 633 at DIS module with voltmeter, other lead to ground and check voltage.
4.0 volts or less, repair open/high resistance in circuit 633, retest to confirm.
Greater than 4.0 volts, go to step 14
Step 14: Inspect terminal on DIS module for looseness or poor connection.
If terminal is bad, repair it.
If terminal is good, replace the DIS module.
That's the entire diagnostics chart, anybody who has done this in the past feel free to throw in your tips/opinions. I would like to add three things:
1. Check the grounding bolt on the DIS module for corrosion.
2. Be sure the secondary wires are fully seated, you should feel/hear a click
3. Use dielectric grease on the coil towers
Bent camshafts can be cause by Many malfunctions, some of the more common include: 1. Engine overheating. 2.Broken timing belts. 3. Bent camshafts can be cause by Many malfunctions, some of the more common include: 1. Engine overheating. 2.Broken timing belts. 3.
Where is crankshaft position sensor located on 99 Chevy silverado 5.3?
It is behind the starter. you can not see or get to it until you remove the starter.
What does a faulty crankshaft sensor do to the car?
Without a signal from the crank sensor, the ECU won't know how fast the engine is turning or "where it is" (which cylinder is about to fire), and the engine will not run.
If the sensor is just "somewhat bad" (and gives a weak or irregular signal), the engine might do things like run badly at certain speeds, stop occasionally, or have trouble starting.
How do you know if a crank position sensor is bad?
You will have a no spark situation. Testing it with a volt meter is easy. Twist the crank shaft slowly by hand and watch volt meter. If there is voltage and no voltage the sensor is good. No readings sensor is bad

near the harmonic balancer, its under the timing pointer.
Where can you find a diagram for the location of the coolant sensor for a 1986 300ZX?
The 300ZX Shop Manual has one page visual for all the components, the sensor located on the drivers side just to the right side of the Distributor. Its screwed into the block near the top of the block and has two fine wires coming out of the sensor.
Where is the crankshaft sensor in a 98 Montero sport?
The 1998 Montero Sport crankshaft sensor will be located on the rear of the engine. The crankshaft sensor is on the inside of the rear engine cover.
Why would a Chevrolet venture crankshaft pulley be out of line?
Because the "Harmonic Balancer", aka, "Cranshaft Pulley" is actually a 2 piece, part. The hard rubber center hub sometimes loses its way, and once it starts 'wobbling', it eventually fails. Symptoms include belts coming off the pulleys, and also them breaking, both in half, and by splitting sideways (making the belt thinner, to accomodate for the new alignment).
Part can be found at most auto parts houses, for about $50.
Needs to be put on with an impact wrench!
Can the crankshaft position sensor cause the car not to start?
yes this will stop car from starting. a bad cam sensor will also stall engine at any speed.the sensor is easy to replace.
Where is the crank position sensor on the 2006 Chevrolet trailblazer?
7 oclock position behind the crankshaft pulley
Where is the crankshaft on a Vauxhall corsa 2001?
Take the top half of your engine off and there you will see the crank shaft
Can the oxygen sensor cause the car not to start?
no it can't. usually when the oxygen sensors are failing, u get your check engine light on.
