Look in either Chilton's Hardcover Manuals or Haynes repair manuals for it. If not, ask a dealer.

Solutions to OBD2 codeS. 2006 Volvo XC90 2.5t codes: P2111 P0336

The CPS is positioned so that these teeth/cogs pass very closely to its magnetic end. As the crankshaft rotates, the raised areas pass by the sensor and complete the electromagnetic circuit. When the indentations (between the teeth) pass the CPS, the circuit is briefly interrupted. Since the camshaft rotates very quickly, the process of repeatedly completing and interrupting the circuit occurs in milliseconds. This progression of completing and interrupting the CPS circuit produces a waveform pattern. This pattern is recognized by the PCM as crankshaft position. The CPS and all of the camshaft position sensors function in much the same manner.
When the engine is running, the PCM constantly compares input signals from the crankshaft and the camshafts. If the crankshaft position is not within a specified degree of variation from the camshaft/s, under a given set of circumstances for a set period of time, a P0336 code will be stored and a malfunction indicator lamp may be illuminated.
Typically, when this code is set, the engine will not start. If the engine does start, it will likely run very poorly. Symptoms of P0336
  • Engine no start condition
  • Hesitation upon acceleration
  • General lack of engine performance
  • Diminished fuel efficiency
Troubleshooting P0336 A diagnostic scanner, a digital volt/ohmmeter (DVOM), a portable oscilloscope, and access to a reliable vehicle information source such as All Data DIY will be needed before attempting to diagnose a code P0336.
Begin with a visual inspection of all system related wiring harnesses and connectors. Wiring circuits, electrical sensors, and/or connectors that have been contaminated with engine oil, coolant, or power steering fluid should be your focus. Petroleum based fluids are known to corrode the protective insulation on wiring and lead to shorted or open circuits and possibly a stored P0336.

What is the cps

Hi there:
A CPS (Crankshaft Position Sensor) is an electronic device used in an internal combustion engine to monitor the position or rotational speed of the crankshaft.

Hope this helps.

Changed the CPS on my 01 330i and still getting same code, car still acting strange. Any suggestions??

This could come from a variety of places... in no particular order... the "new" CPS is bad (get another one)... The battery is weak or has low voltage (replace battery)... The DME may need an update / DIS CD 30.0 or higher... dealer or good Independent shop can do this) last one to look at is the fuel filter (replace)

I am looking for the location of the CPS

Hi there,

The Crankshaft Position Sensor(CPS) is attached to the bell housing of your vehicle. The CPS detects teeth on the flywheel as they pass the sensor during engine operation and thus provides the computer with info concerning engine speed and crankshaft angle.

Hope this helps. Best of luck...

2005 Kia Sedona, Trouble Code P0320. Everything I read online tells me its a Crankshaft Sensor. I called Kia and then sent me to were it says that the code is an Ignition System Failure...

This is a common problem usually related to the crankshaft position sensor. Before you replace it, disconnect the electrical connector to the CPS sensor and clean it with electrical contact spray and add a dab of dielectrical grease. If the problem continues, replace the CPS sensor. It is easy to replace and is not very expensive. It just bolts to the engine block with one or two bolts. I believe the CPS sensor on the Sedona is behind the timing cover on the front of the engine.

For what sensor is the code po340 on a dodge neon 04 and how i change.

This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.

With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:

  • Visually inspect all the wiring and connectors in the circuit
  • Check for continuity in the circuit wiring
  • Check the operation (voltage) of the camshaft position sensor
  • Replace the camshaft position sensor as required
  • Check the crankshaft position circuit as well
  • Replace circuit wiring and/or connectors as required
  • Diagnose/replace the PCM as required

I need some info on the were abouts,and how much im gittin in over my head with changein the crankshaft positioning sensor on my 1994 lexus LS 400?

It's not too bad of a project. Your CPS (Crankshaft Position Sensor) is located in the engine compartment, front engine area / driver's side, mounted in the engine block above the crankshaft pulley. I've provided a photo below to give you a better idea of what your looking for.

To remove the CPS, simply disconnect the wire harness and remove the mounting bolt. From there, the CPS should slide right out.

When installing your new CPS, make sure to check the tip to ensure it came with a new spacer (will be attached to the tip). Thereafter, install the sensor until the spacer lightly touches the sensor ring. Tighten the sensor mounting bolt to approximatley 105 and attach the wire harness.

Help this helps and good luck!

A. See web link at bottom of page. Some 1989 and early 1990 vehicles equipped with the 4.0 liter engine and automatic transmission may experience an engine no-start, hard restart, or an engine die-out. This condition may be caused by low signal strength from the Crankshaft Position Sensors (CPS) due to a larger than desired distance to the engine flywheel sensing ring.
What you need to do is check to see if the vehicle has a slotted crank position sensor. If the vehicle is equipped with a slotted crank position sensor, Figure 1, check to see if the CPS grommet on the top of the transmission bell housing has been updated,see Figure 2. If the CPS grommet has not been updated, replace the CPS grommet.
You'll need a Crankshaft Position Sensor, slotted, part number 83100067 and Crankshaft Position Sensors Grommet, dust cover, part number 83100068. When you install it, make certain that the CPS is completely bottomed on the machined lip of the bellhousing and is as close as possible to the flywheel sensing ring without contacting it. go to this web page for diagram:
