Hi Adam, of course there is an o-ring for the sensor if your dealer is not being friendly try a reputable independent shop that works on Yamaha and I am sorry you can't find the first and best tool you ever bought for your Yamaha but despair not for a mere $15.00 you can download another one. For more information about your issue, please visit the websites below. Good luck and have a nice day.

SOURCE: oil leaking out of overflow

just check the crankcase filter to make sure it isn't stopped up if it is that will make the crankcase build up pressure and blow the oil out

SOURCE: How to check my oil level on 04 Yamaha yzf 600

YZF600R is a carbureted model. OIL: The oil sight glass is a round window, low on the right side. Very hard to try to see when astride the bike, even if you use a mirror on an extension rod. Have a friend hold the bike level,perhaps, while you check. Oil should be sighted after the bike has been sitting for a time after riding. I suggest using a good 10W-40 regular motorcycle oil (Least expensive around here in Boston is to buy Kawasaki by the gallon at Riverside) I found the pesky 1st-to-2nd shift to be more direct with this oil than with synthetic. I had plenty of opportunity to compare the two types. GAS: No reserve, but as noted, there is a low fuel light, in the row of lights that includes the neutral light and the high beam indicator. You ought to be getting over 50 m.p.g., so you can estimate your 'range' from that. I usually fill up again around the 180 mile period. I think I've seen the low fuel light once in 6 years of ownership. OH: I suggest you treat the gas, on a regular basis, with 'marine' Stabil, not the regular stuff. I have had a 'gummy' Yamaha Virago 250 to care for, that I thought would never clear its fuel problems. Last winter ('08-'09) stored it with the marine Stabil in the tank and run for a while to get it into the carbs also. Within a few minutes of running it this spring-actually a couple weeks ago- it smoothed out and has run fine since. I believe this HAS to be as a result of the treatment of the fuel (run through the carbs before the winter storage) with this special Stabil. It was recommended by Carlo at Riverside- I'll have to remember to thank him for the advice. N.B. I always change the fuel (siphon it out, put that Stabil'ed but 'old' stuff into my car tank, refill the bikes with fresh 93 octane) each Spring.

What does this code mean

Does the truck run ok? If so may just be bad sensor .it reads the correlation between cam and crank shafts so timing is correct so the camshaft control the valves and crankshaft controlling the pistons don't hit each other

No. If changing the crankshaft position sensor, a relearn procedure needs to be done. This requires a dealer to do.

Where are the crankshaft sensors on a 2001 cadillac deville sedan?

The crankshaft position (CKP) sensor is a three wire sensor based on the magneto resistive principle. A magneto resistive sensor uses two magnetic pickups between a permanent magnet. As an element such as a reluctor wheel passes the magnets the resulting change in the magnetic field is used by the sensor electronics to produce a digital output pulse. This system uses two sensors within the same housing for the V6 engine, and two separate sensors for the V8 engine. The PCM supplies each sensor a 12-volt reference, low reference, and a signal circuit. The signal circuit returns a digital ON/OFF pulse 24 times per crankshaft revolution.
Removal & Installation

  1. Raise and support the vehicle.
  2. Remove the air deflector.
  3. Remove the oil filter adaptor.
  4. Disconnect the crankshaft position sensor electrical connector.
  5. Remove the crankshaft sensor retaining bolt.
  6. Remove the crankshaft sensor.

To install:

NOTE Inspect the crankshaft sensor O-ring for wear or damage. If a problem is found, replace the O-ring.
  1. Lubricate the crankshaft sensor O-ring with clean engine oil.
    NOTE Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
  2. Install the crankshaft sensor and the retaining bolt. Tighten the retaining bolt between 10 Nm (89 inch lbs.).
  3. Connect the crankshaft position sensor electrical connector.
  4. Install the oil filter adaptor.
  5. Install the air deflector.
  6. Lower the vehicle.
  7. Operate the engine and inspect crankshaft sensor for engine oil leaks.
  8. Perform the CKP System Variation Learn Procedure.
Hope helps.

Crankshaft position sensor

Crankshaft Position Sensor Engine speed is a very important input to the Engine Management System (EMS). 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 located in close proximity to the crankshaft.
In addition, the EMS uses minute variations in the CKP sensor data to determine engine misfire. The EMS uses this information in conjunction with the camshaft position sensor to perform misfire diagnostics.
Related Symptoms 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.
NOTE: For procedures on the position sensors, please refer to Driveability and Emissions.

Jsut want to know where crankshaft position sensor


here are illustrations of the CKP (crankshaft position) sensor in 2.3L and 3.0L.

Note: In the bottom of the 2.3L drawing says Trottle Position (TP) Sensor, this is wrong, It should say CKP Sensor.

2.3L Engine

The Crankshaft Position (CKP) sensor is located to the left of the crankshaft pulley.

3.0L Engine

The Crankshaft Position (CKP) sensor is located just behind the crankshaft pulley on engine block.
