The engine has been replaced. Important: While the learn procedure is in progress, release the throttle immediately when the engine starts to decelerate. Time B indicates that the Sensor B signal is being used. Do you thnk the procedure is possible without a scan tool? Remove the crankshaft retaining bolt. Installation Procedure Important Inspect the crankshaft sensor o-ring for wear or damage.
Haven't had a problem with the car yet. Stop the vehicle and idle for 2 minutes with the brake applied and the transmission in Drive automatic trans. The engine control is returned to the operator and the engine responds to throttle position after the learn procedure is complete. If a problem is found, replace the o-ring. The best way to check the outputs and timing is with an oscilloscope. If a problem is found, replace the o-ring.
Select and enable the crankshaft position variation learn procedure with the scan tool. But it could be rough up to that point, but the worst stumbles and stalls were at that point. Apply and hold brake pedal. A misfire causes an unexpected change in the crankshaft speed. The scan tool only displays the condition that inhibits the procedure.
The scan tool monitors certain component signals to determine if all the conditions are met to continue with the procedure. To start viewing messages, select the forum that you want to visit from the selection below. There really is no 'learning' procedure when it comes to timing the Vortec V6 and V8's. Then 3 weeks later it did it again. If the sensor loses its A or B input, an intermittant loss of spark will occur, usually this will lead to a momentary misfire condition, but depending on engine conditions the engine could stall. The best way to check the outputs and timing is with an oscilloscope. Remove the crankshaft sensor electrical connector.
Perform 4 deceleration cycles, without using the brakes, of 25 seconds each where no specific speed is necessary. After surgery the engine starts good, drives good but: the engine have rough idle - only a little. The dual sensor allows the engine to run even if one signal is lost. But atleast i dont have to use that ancient Genesis. A misfire causes an unexpected change in the crankshaft speed. Remove the crankshaft sensor electrical connector.
. Perform 4 deceleration cycles, without using the brakes, of 25 seconds each where no specific speed is necessary. Why the 70 deg C or 158 deg F temp engine coolant temp in order to program the Crankshaft Position System Variation Learn Procedure? Lubricate the crankshaft sensor o-ring with clean engine oil. Lubricate the crankshaft sensor o-ring with clean engine oil. I just did one on a 3800 and either my scan tool or Mitchel 1 have another procedure if you do not have a scan tool. The engine control is returned to the operator and the engine responds to throttle position after the learn procedure is complete.
Installation Procedure Important Inspect the crankshaft sensor o-ring for wear or damage. The sensor only got worse over time. Install the crankshaft sensor and the retaining bolt. The scan tool displays Learn Status: Learned this ignition. That's when it switches to sensor A from B at this certain heat range.
It can also be performed by some aftermarket scan tools. With the Air temperature sensor and Coolant temperature within 5 degrees Centigrade of each other, start the engine and let it idle in Park or Neutral for two minutes. If there is any power train trouble code other than P1336 Crankshaft Position Variation not learned , the computer will disable the relearn function until the problem that caused the code has been eliminated. Awesome chicks and it is absolutely free! Operate the engine and inspect crankshaft sensor for engine oil leaks. Returning to 45 mph for 15 seconds in between deceleration cycles.
