2001 Chevrolet Chevy K Silverado Crankshaft Position Sensor Engine Stall Service Procedure

Why is your vehicle being recalled? Your vehicle may have a condition in which the crankshaft position sensor can fail intermittently or permanently. If the sensor fails intermittently, the Service Engine Soon (SES) light may illuminate and the vehicle may run rough. In addition, the engine may stall, and if so, may re-start immediately or after a cool down period. If the sensor fails permanently, the engine will quit running and will not re-start. If this happens while the vehicle is moving, a crash could result without prior warning. What will we do? Your GM dealer will replace the crankshaft position sensor. This service will be performed for you at no charge . Because of service scheduling requirements, it is likely that your dealer will need your vehicle longer than the actual service correction time of approximately one hour and twenty minutes. What should you do? You should contact your GM dealer to arrange a service appointment as soon as possible. Bring the enclosed customer reply form with you when you visit your dealer. The form identifies the repairs required. If you no longer own this vehicle, please let us know by completing the form and mailing it back to us. Did you already pay for this repair? The enclosed form explains what reimbursement is available and how to request reimbursement if you have paid for repairs for the recall condition.

1993 Ford Crown Victoria V8-281 4.6L SOHC Engine – Lean Driveability Symptoms Manual

1. Look at the BARO PID. Refer to the Barometric Pressure Reference Chart in this article. At sea level, BARO should read about 159 Hz (29.91 in. Hg). As a reference, Denver, Colorado at 1524 meters (5000 ft.) altitude should be about 144 Hz (24.88 in.Hg). Normal learned BARO variability is up to +/- 6 Hz (+/- 2 in. Hg.). If BARO indicates a higher altitude than you are not at (7 or more Hz lower than expected), you may have MAF contamination. If available, Service Bay Diagnostic System (SBDS) has a Manifold Absolute Pressure (MAP) sensor that can be used as a barometric pressure reference. Use “MAP/BARO” test under “Powertrain,” “Testers and Meters.” Ignore the hookup screen. Connect GP2 to the reference MAP on the following screen. 2. On a fully warmed up engine, look at Long Term Fuel Trim at idle, in Neutral, A/C off, (LONGFT1 and/or LONGFT2 PIDs). If it is more negative than -12%, the fuel system has learned lean corrections which may be due to the MAF sensor over-estimating air flow at idle. Note that both Banks 1 and 2 will exhibit negative corrections for 2-bank system. If only one bank of a 2-bank system has negative corrections, the MAF sensor is probably not contaminated. 3. On a fully warmed up engine, look at MAF voltage at idle, in Neutral, A/C off (MAF V PID). If it’s 30% greater than the nominal MAF V voltage listed in the Powertrain Control/Emissions Diagnosis (PC/ED) Diagnostic Value Reference Charts for your vehicle, or greater than 1.1 volts as a rough guide, the MAF sensor is over-estimating air flow at idle. 4. If at least tow of the previous three steps are true, proceed to disconnect the MAF sensor connector. This puts the vehicle into Failure Mode and Effects Management (FMEM). In FMEM mode, air flow is inferred by using rpm and throttle position instead of reading the MAF sensor. (In addition, the BARO value is reset to a base/unlearned value.) If the lean driveability symptoms go away, the MAF sensor is probably contaminated and should be replaced. If the lean driveability symptoms do not go away, go to the PC/ED Service Manual for the appropriate diagnostics.

3406E Truck Engine Installation OR Removal Of The Speed/ Timing Sensor

1. Disconnect the speed/timing connector “P9/J9″ (2) . Inspect the connector for the following conditions. * Corrosion * Bent pins * Missing pins * Damaged sockets * Mismating * Broken wires 2. Remove the Speed/timing sensor (1) from the front gear cover. 3. Examine the plastic end of the sensor for signs of wear or contaminants such as metal filings. The plastic end of the speed/timing sensor should have no contaminants and should show no wear (greater than 0.051 mm (0.0020 inch) from the face) . 4. Use a screwdriver to carefully pry the plastic sensor end to the fully extended position (approximately 4.775 mm (0.1880 inch) beyond the metal housing of the sensor). 5. Gently push in on the plastic end of the sensor. The plastic end should be firm. The plastic end should resist movement in the retract direction. If there is no resistance replace the sensor 6. Remove the two bolts (3) and remove the cover (5) from the flywheel housing. This hole is used for engine turning. 7. Put one bolt (3) in the timing bolt location (4) . The timing bolt location is approximately 127 mm to 152 mm (5 inch to 6 inch) above the hole in the flywheel housing for engine turning. I 8. Use 9S-9082 Engine Turning Tool (6) and a 1/2 inch drive ratchet wrench to turn the engine flywheel in the direction of normal engine rotation. The normal engine rotation is in a counterclockwise direction when viewed from the flywheel end. Turn the engine flywheel until the timing bolt engages with the threaded hole in the flywheel. Note: Visually check the location of the tooth on the wheel on which the speed/timing sensor is to be positioned. The end of the sensor must be in alignment with a tooth on the wheel and not in alignment with the valley of the wheel. Note: The No. 1 piston must be at either top center of the compression stroke or at top center of the exhaust stroke. 9. Inspect the speed/timing sensor before installation. Use steps 3 through step 6 to inspect the sensor. 10. If the sensor end is not fully extended, use a screwdriver to carefully pry the plastic sensor end to the fully EXTENDED position approximately 4.775 mm (0.1880 inch) beyond the metal housing of the sensor.
