The crankshaft positions sensor is located behind the crankwheel on the passenger side of the engine. In order to replace it or at least examine it, a person would need to remover the crankwheel with a puller that can be rented out at Autozone. Just ask for a harmonic balancer puller. Remove the front right tire and place firmly on jackstands. The crankshaft pulley WILL NOT loosen by just turning the bolt. This is a two person job. Caddycorner to the starter, there is a small plastic plate cover that covers the driveplate/flexplate. Remove the two bolts and pull the cover off. Have one person position a screwdriver into the ring gear teeth and have another remove the pulley bolt. Its EXTREMELY TIGHT and the best way to remove it is with a large rachet and a breaker bar. Once the bolt is removed, take the puller and position accoridngly. The threaded holes are not on the surface but inside the pulley itself. Place large bolt in center of the puller and place the pointed or flat tip on center of the large bolt and place. Take three very small screws or bolts that came with the puller and position all three in place. Once all this is done begin turning the bolt in the middle of the puller clockwise. This will take alot of arm strength and anywhere from 15-30 min to do. Once the wheel has come off, carefully pry off the sensor cover which is another piece of plactic. Once the cover is off, carefully remove the sensor and examine or replace as needed. Installation is reverse of removal. Hope this helps

    Okay I was going to take it to a car repair shop so I tried and put some gas in the car and it started, Its my wife car her gas gauges , speed odometer all that stuff doesn't work she goes by a digital mile to empty, it say she had 156 to empty, I put gas in it and it ran a littlr ruff so I took it to auto zone and they put a tester on it and it read "the cam sensor and the oxygen sensor could be defective but the car is running pretty good now, I guess my question is do you think the cam sensor is the reason the car stopped and two days later it started and should I spend the money I don't have to have somebody repair the two sensors now?

SOURCE: crankshaft position sensor location

1990 Chevrolet Cavalier 2.2L TBI 4cyl
The Crankshaft Position Sensor is located under hood, center, rear engine area, below ingnition coil pack and DIS module, mounted in engine block.

Fig. 1: View of the CKP sensor-to-crankshaft reluctor relationship

Crankshaft Position (CKP) Sensor
A magnetic crankshaft sensor (Hall Effect switch) is used which is remotely mounted on the opposite side of the engine from the DIS/IC module. The sensor protrudes in to the engine block, within about 0.050 in. (1.27mm) of the crankshaft reluctor.

I really hope help you wuth this (rated this help). have a nice day, good luck.

SOURCE: Where and how many o2 sensor's on a 2003 chevy impala?

There are two sets of 02 sensors on most cars today. On set is set directly behind the header, one on each side, if it is a V engine. This set is used for the engine's ECU to control timing as well as other variables. The other set is placed on a bung in your Catalytic converter. This 02 sensor is used for emissions purposes only.

Where is the 7x crankshaft position sensor on a 2004 chevy impala 3400 engine. Are there any tricks that I need to know to change it?

Crankshaft Position (CKP) Sensor B (LA1)
Middle rear of the engine, below the exhaust manifold

Turn the steering wheel fully to the left.
Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
Remove the right front wheel. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
Disconnect the crankshaft position (CKP) sensor electrical connector.
Remove the CKP sensor bolt.
Remove the CKP sensor.
Inspect for wear, cracks, or leakage if the sensor is not being replaced.

ā€¢ Crankshaft position (CKP) sensors
The CKP sensor B is a variable reluctance sensor. The magnetic field of the sensor is altered by a crankshaft mounted reluctor wheel that has seven machined slots, six of which are equally spaced 60 degrees apart. The seventh slot is spaced 10 degrees after one of the 60 degree slots. This sensor provides the ignition control module (ICM) with 7X signals, or seven pulses for each revolution of the crankshaft. The pulse from the 10 degree slot is known as the sync pulse. Both of the sensor circuits are connected to the ignition control module (ICM). A signal converter within the ICM produces digital 3X output pulse to the powertrain control module (PCM), the 3X reference is known as the low resolution engine speed signal.
The CKP sensor A contains a hall-effect switch. A hall-effect switch is a solid state switching device that produces a digital ON/OFF pulse when a rotating element passes between the sensor tip and a magnet. This rotating element is called an interrupter ring or blade. In this case the interrupter ring has 24 evenly spaced blades and windows and is part of the crankshaft damper assembly. This sensor provides the PCM with 24X signals, or 24 identical pulses per crankshaft revolution. The 24X signal is used for enhanced smoothness and idle stability at a lower calibrated RPM. The PCM supplies the sensor with a 12-volt reference, low reference, and signal circuit.

Where is the idle sensor in the 2000 chevy impala

There is no idle sensor on the 2000 Chevrolet Impala, according to my online resource.

But, there is the following that senses rpm of the engine and thus the idle speed when the Throttle Position Sensor is at 5% or the accelerator pedal is not depressed:

Crankshaft Position Sensor Operation Engine speed is a very important input to the Powertrain Control Module (PCM). Crankshaft speed and position are the basis for many calculations made by the computer. Crankshaft position values are transmitted to the computer by pickup coils also known as Permanent Magnet (P/M) generators, Hall Effect sensors or optical sensors. The Crankshaft Position Sensor (CKP) also known as engine speed sensor is typically located in proximity to the crankshaft.
In addition, the PCM uses the CKP sensor in conjunction with the camshaft position sensor to calculate and perform misfire diagnostics.
Related Symptoms
  • A No Start / Intermittent Start condition - Can be caused by a faulty crankshaft position sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit.
  • Engine Misfire Diagnostic Trouble Codes
NOTE: Engine Mechanical conditions can also create the same or similar symptoms. (Don't overlook basic mechanical integrity).
