SOURCE: falls dead when driving, will restart after awhile

Did you try checking or replacing the coolant sensor? I think you should replace it along with the thermostat. Are there any problems like sputtering or any unusual noises or symptoms? Smoke, anything?

SOURCE: replacing harmonic balancer and crankshaft sensor on 1992 Olds 88

The bolt is a right hand thread. And the sensor is not adjustable. It is a straight forward install.

SOURCE: 1991 Olds Cutlass Ciera 3.3 v6 would start, run a

jrtvett's "unplug one injector and start" troubleshooting procedure would work if one injector is bad. If more than one injector is bad, then not so sure.
Like you mentioned, one or more injector(s) can go bad and it causes the others to stop working as well. After our experience, I am convinced this observation (fault mode) is correct (see below). Its as if upon warmup the solenoid in the faulty injector shorts, resulting in short circuit of signals to all the other injectors.
We have a 1989 Olds Cutlass Ciera with the 2.8L V6 that recently had the same fault: At least one injector went bad after warmup, then engine refused to restart. All other possibilities were eliminated, including crank shaft sensor, ECM, ignition pack, idle start valve, bad gas, rail pressure, etc.
No Service Engine light illuminated, and there were no fault codes in the ECM computer.
The jrtvett procedure could not easily be utilized in our case because all the injector connectors are underneath the intake manifold and inaccessible.
My cousin is a Ford mechanic told me of an analysis procedure Ford uses to troubleshoot injector problems. They display rail pressure on a LCD or CRT monitor and can see pressure drop with each injector's opening. Unfortunately, if the car is not starting, then this test will not be of much use. The engine has to be idling or at least all of the solenoids in all of the injectors operational to use this test. If engine won't start, then its clear none of the injectors are opening as described above, then no fluctuations in rail pressure would be displayed.
The shop that was working on our car decided to replaced all of the injectors, and the engine now runs like new.
Due to inaccessibility of injectors and fact these injectors were inexpensive ($40-$50 each), it was wise just to replace all six. Grading old injectors is not exact science.

Is their one or two crank sensors on a 2003 olds alero


What engine does yours have ? 2.2L 4 cyl. or 3.4 L V-6 If you have 3.4 L it has two A an B

• 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 crank shaft sensor located on a Buick century 3.1 2001


Which one ? your 3.1 l has two .7 X an 24X
The 7X (CKP) sensor is bolted into the center of the engine block and protrudes into the crankcase. The 7X CKP sensor reluctor wheel is cast into the crankshaft.
The 7X CKP sensor is a variable reluctance sensor. The magnetic field of the sensor is altered by a reluctor wheel that has seven machined slots, six of which are equally spaced 60 degrees apart. The seventh slot is spaced 10 degrees from one of the other slots. The 7X CKP sensor produces six pulses and one sync pulse for each revolution of the crankshaft. This signal must be present for the IC module to send a 3x reference signal to the PCM. The 3X reference is known as the low resolution engine speed signal.
The 24X (CKP) sensor (1), secured in a mounting bracket (3) and bolted to the front side of the engine timing chain cover (2), is partially behind the crankshaft balancer. The crankshaft balancer contains the 24x CKP sensor interrupter ring.
The 24X CKP sensor contains a hall--effect switch. A hall -- effect switch is a solid state switching device, which produces an OFF-ON pulse when a rotating element passes between the sensor tip and a magnet. This rotating element is called an interrupter ring. In this case the interrupter ring has 24 evenly spaced blades and windows. This sensor produces 24 ON-OFF signal pulses per crankshaft revolution. The 24X signal is used for enhanced smoothness and idle stability at a lower calibrated RPM. The 24X signal is known as the medium resolution engine speed signal.

I got a 2001 olds silhouette, 3.4, with p1374. Checked ecm and replaced cps on the side of the block. ran great for about 4 miles, then it started stumbling and then stalling.


DTC P1374
The 3X reference signal is produced by the ignition control (IC) module. The IC module calculates the 3X reference signal by dividing the crankshaft position (CKP) sensor 7X pulses by 2 when the engine is running and when the CKP synchronizing pulses are being received. The powertrain control module (PCM) uses the 3X reference signal to calculate the engine RPM and the crankshaft position at engine speeds above 1600±150 RPM. The PCM also uses these pulses to initiate injector pulses. The PCM compares the 3X reference pulses to the 24X CKP pulses and the camshaft position (CMP) sensor pulses. If the PCM receives an incorrect number of pulses on the 3X circuit, a DTC P1374 will set and the PCM will use the 24X CKP reference circuit for fuel and ignition control. The engine will continue to start and run using only the 24X CKP and the camshaft position sensor signals.

Diagnostic Aids
• DTC P1374 can be caused by secondary components leaking high voltage into the IC module.
• Inspect for the following conditions:
- Incorrect harness routing near secondary ignition components
- Ignition coil arcing to wiring harness or IC module--Inspect the ignition coils for the following conditions:
• Cracks
• Carbon tracking
• Other signs of damage
- Ignition coil arcing to wiring harness or IC module--Inspect the ignition coils for the following conditions:
- Secondary ignition wires arcing to wiring harness
I would sugest you take your vehicle to a qualified repair shop an have it diagnosed , but i can tell that's not your way , is it . We diagnose not replace part's .
Replace the IC module. Refer to Ignition Control Module Replacement .
Did you complete the replacement?
Go to Step 11

Replace the PCM. Refer to Powertrain Control Module Replacement .
Did you complete the replacement?

Our 1999 Buick century is having problems with running it won't hardly take gas and the transmission won't shift up sometimes the same time the transmission messed up the speedometer quit working


Is the check engine light on ? Have checked for codes , may have transmission codes stored . Check engine light doesn't need to be on for codes to be stored . VSS - vehicle speed sensor is a input to PCM.
The Vehicle Speed Sensor (VSS) is a gear-driven permanent magnet generator housed in the transaxle. The sensor generates a sine wave output with a frequency proportional to the vehicle speed. The Powertrain Control Module (PCM) converts the signal to an output that switches to ground at a frequency of 4000 pulses per mile. The signal (CKT 817) is used by various vehicle components. The signal CKT 817 drives the following components:
• The speedometer
• The odometer May also have problems with mass air flow sensor , crankshaft position sensor , cam sensor etc...
DTC P0336 Crankshaft Position (CKP) Sensor Circuit
The 24X reference signal is used to improve idle spark control at low engine speeds. The PCM uses the 24X reference signal to calculate engine RPM and crankshaft position at engine speeds below 1600 RPM. The PCM constantly monitors the number of pulses on the 24X reference circuit and compares the number of 24X reference pulses to the number of 3X reference pulses and CAM signal pulses being received. If the PCM receives an incorrect number of pulses on the 24X reference circuit, DTC P0336 will set and the PCM will use the 3X reference signal circuit for fuel and ignition control. The engine will continue to start and run using the 3X reference and CAM signals only.
There are a lot of electronic thing's on you Buick that can go haywire causing the problems you have . If you are unfamiliar with these thing's I mentioned , I suggest you take it to a ASE certified repair shop . Some people get irate just mentioning this, It mite save you money in the long run .

Engine stalls while driving


That would be a symptom of a crankshaft postion sensor going bad . Shorting out when heated up . But unfortunately thier are other sensors that can cause the same problem . Plus the ICM - ignition control module could cause that problem as well . OH yea , almost forgot you vehicle has two crankshaft position sensors . You best bet , take it to a qualified repair shop that has the diagnostic tools to trouble shoot the problem .
The electronic ignition (EI) system consists of the following components and wiring circuits:
• The ignition control (IC) module
• The ignition coils
• The powertrain control module (PCM)
• The 24X crankshaft position (CKP) sensor
• The 7X CKP sensor
• The camshaft position (CMP) sensor
The EI wiring circuits listed here use the following service common names. Between the IC module and the PCM:
• Low resolution engine speed signal
• IC timing control
• IC timing signal
• Low reference
Between the 7X CKP sensor and the IC module:
• CKP sensor (1) signal
• Low reference
Between the 24X CKP sensor and the PCM:
• Medium resolution engine speed signal
• 12-volt reference
• Low reference
Between the CMP and the PCM:
• CMP sensor signal
• Low reference
• 12-volt reference
The IC module also receives power and chassis ground through the following circuits:
• Ignition (1) voltage
• Ground

When it stalls check for spark , pull spark plug wires off the same coil an crank the engine . Is thier spark jumping from one coil tower to the other ? Make sure it's a lack of spark problem .

Where ie the 2 crank sensors on a 1999 buick century with 3.1 engine



  1. Crawl under the front of the vehicle and look up at the back side of the engine. The crankshaft position sensor is made from black plastic and has a two-wire connector attached to it. The sensor is located on the back side of the engine block, halfway between the oil pan and the top of the block.


have a great holiday !! they only use one sensor, a 3x or 24x. above is for 3x sensor, to replace 24x just call an auto parts store and they should tell you the location and how to change it.
