The CMP sensor is located somewhere on the head. Usually means either you need to replace the main seal or more likely your timing is off and you need to replace your timing belt or chain.

SOURCE: Where is the Crank Sensor '99 BMW 523i E39 Auto

are you sure you need the crankshaft position sensor changed. it is at the back of the engine i believe, but.....
check for a wet ecu first... read the note on e36...

the ecu compartment is under the windshield on the passenger side on E36

you gain acess to it under the hood....
this compartment gets wet, the ecu lays on a flat surface in that
compartment.

the bottom side of the circuit board gets wet and starts corrosion.

remove the ecu, take the bottom plate off, clean the bottom of the circuit
board with alcohol and a soft tooth brush.

you should be able to see the signs of corrosion or conductive build up.

this gunk bridges solder points doing all sort s of wierd things to your
car, including false sensor readings from asc/abs controllers and other
sensors....

all the way to engine failure and worst case burnt and shorted wiring
harness.

I'm on my 3rd ecu, took me and the repair boys a few years to figure this
one out.

BTW: i would get that ecu mounted above that flat surface, use some sort
of standoff to raise it so that it is not laying in the wet.

SOURCE: HELLO, I HAVE TROUBLE CODES PO330,PO340, ON MY

The Cam Position Sensor is a common item to fail. However, the cam positioning mechanism can fail too giving that code.

There are two sensors and the Exhaust Cam Sensor is most common to fail. I always replace both.
Te CKP's are on the top front of the engine next to the cylindrical operation solenoids.

Knock sensors fail too and need checked or correct feedback to ECU with a scanner.
Find a shop near you at http://www.iatn.net/shopfinder/

These engines require regular oil changes with quality synthetic oils and OE filter....not a FRAM or WIX !

Buy only BMW sensors ...aftermarket have high failure rate.

SOURCE: how do i reset the

unless you have a scan tool you can not reset the faults in a BMW even if the check engine light is out there will still be faults stored in the system you have to have a shop clear the code thats the only way. disconnecting the battery will not help in any way i have been a bmw master technician for 10 years now.

I have a 2010 hhr chevy. im getting a no correlation code. cam and crank sensors. 0016 and 0017 codes. does anyone know the real prob?

Not without having the vehicle here an doing some testing .
DTC P0016: Crankshaft Position (CKP) - Intake Camshaft Position (CMP) Correlation
DTC P0017: Crankshaft Position (CKP) - Exhaust Camshaft Position (CMP) Correlation

Circuit/System Verification
Note: The scan tool control of the CMP actuator is inhibited when DTC P0016 or P0017 sets.
Command each CMP actuator to 25 percent. The CMP actuator angle desired parameter should match the CMP actuator actual parameter.
Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
Circuit/System Testing
Note: Incorrect engine oil viscosity, aftermarket engine oil additives, or engine oil that is overdue for changing, can greatly affect the performance of the camshaft actuator.
Ignition OFF, inspect the crankshaft balancer bolt for the proper torque. Refer to Fastener Tightening Specifications.
Remove the CMP actuator solenoid. Refer to Camshaft Position Actuator Solenoid Valve Replacement.
Connect a fused jumper wire between the CMP actuator high control circuit terminal A at the solenoid and B+. Connect a jumper wire to the CMP actuator low reference circuit terminal B at the solenoid. Momentarily touch the jumper wire to ground. Observe the spool valve inside the CMP actuator. The spool valve should move from fully closed to fully opened position.
? If the spool valve inside the CMP actuator solenoid does not move, replace the CMP actuator solenoid.
Inspect the CMP actuator for binding or being stuck.
Inspect the engine for the following conditions:
• An incorrectly installed camshaft sensor
• An incorrectly installed crankshaft sensor
• An incorrectly installed camshaft actuator
• Incorrect valve timing
• A loose camshaft reluctor wheel
• A loose crankshaft reluctor wheel
• Excessive crankshaft end play

2007 Saturn Aura XR 3.6 code p00116. new timing chains and all parts...128,000 miles any ideas besides the crankshaft reluctor.. Car runs great idols smooth

you got a bit carried away with the code
code p 0016 refers to crank shaft position/cam shaft position sensor, bank 1 sensor A---correlation === causes --wiring---CKP sensor --CMP sensor ---mechanical fault
code p 0011 refers to cam shaft (CMP) intake /left /front bank 1 --timing over advanced / system performance==== causes ---valve timing---engine mechanical fault --- CMP actuator ---wiring
you didn't mention the fault so consider this
if the timing is out on the intake cam shaft , it will idle good but play up as the timing actuator moves it further advanced with rpm
if the actuator is not wire properly or the solenoid is faulty , then the inlet will lag with increased rpm and again cause you problems
It is doubtful if the position sensors for either the crank or cam shafts are a problem because it starts and idles good

2001 audi a4 quatro 2.8l DOHC check engine light is flashing and my scanner gave the fault code p0305 and a pending code p1340 . What should I do tofix the problem?

p 0305 is misfire on no 5 cylinder code p1340 refers to camshaft (CMP) sensor 1 bank/ crankshaft position (CKP) sensor ---out of sequence === causes ---valve timing--CMP/CKP sensor installation---CKP sensor rotor
misfires are more injector problems that plugs
take it to an authorized service center for the position senor and valve timing problems

DTC P0013: Exhaust Camshaft Position (CMP) Actuator Solenoid Control Circuit
It may not even be a cam sensor problem !
DTC P0340: Intake CMP Sensor Circuit

DTC P0365: Exhaust Camshaft Position (CMP) Sensor Circuit
DTC P0341: Intake Camshaft Position (CMP) Sensor Performance

DTC P0366: Exhaust Camshaft Position (CMP) Sensor Performance
Camshaft Position (CMP) Actuator System
The camshaft position (CMP) actuator system is an electro-hydraulic operated device used for a variety of engine performance and operational enhancements. These enhancements include lower emission output through exhaust gas dilution of the intake charge in the combustion chamber, a broader engine torque range, and improved fuel economy. The CMP actuator system accomplishes this by changing the angle or timing of the camshaft relative to the crankshaft position. The CMP actuator simply allows earlier or later intake and exhaust valve opening during the four stroke engine cycle. The CMP actuator cannot vary the duration of valve opening, or the valve lift.
During engine OFF, engine idling conditions, and engine shutdown, the camshaft actuator is held in the Park position. Internal to the CMP actuator assembly is a return spring and a locking pin. During non-phasing modes of the camshaft, the return spring rotates the camshaft back to the Park position, and the locking pin retains the CMP actuator sprocket to the camshaft

I have a 1996 Geo prizm automatic 1.6L with a code P0340 Left bank. Single Bank 1. What does that mean? It is saying Camshaft Position Sensor. Where is this located? How do I go about fixing it? Please...

  • If you want to dig into the timing belt you can but I would start by replacing the dizzy, if it were me. No junkyard parts for this. Re-manufactured if not new.

  • Hope this helps.

Where does the cam position sencer located at

It's officially called a CMP Syncronizer.
There are stern warnings on the page associated with this.
CAMSHAFT POSITION (CMP) SENSOR Removal & Installation
CMP sensor is located on rear of engine, behind intake manifold. Before removing, note position of electrical connector on CMP sensor. Remove upper intake manifold. See UPPER INTAKE MANIFOLD . Disconnect CMP sensor. Remove CMP sensor screws and CMP sensor. To install, reverse removal procedure. Ensure CMP sensor electrical connector is pointing in original direction. Tighten CMP sensor to specification.
2 . Failure to use synchro positioner during installation will cause fuel injection to be out of time and may cause engine damage.
CAUTION: DO NOT rotate crankshaft when Synchro Positioner (T95T-12200-A) is positioned on CMP synchronizer. Armature tab will be damaged and synchronizer timing may be shifted. Removal
1. Position crankshaft to TDC of cylinder No. 1, on compression stroke. Note position of electrical connector on CMP sensor. 2. Disconnect negative battery cable. Unplug harness connector from CMP sensor. Remove CMP sensor screws and CMP sensor from positioner. Remove synchronizer hold-down bolt and CMP synchronizer.
Fig. 2: Exploded View Of CMP Synchronizer Assembly (Typical) Courtesy of FORD MOTOR CO.
CAUTION: DO NOT rotate crankshaft while synchronizer is removed from engine. Installation
1. Install Synchro Positioner (T95T-12200-A) on synchronizer housing. See Fig. 3 . Rotate synchronizer shaft until vane on shaft aligns with slot on synchro positioner. Rotate synchro positioner until engaged into notch in housing. Dip drive gear in engine oil.
Fig. 3: Installing Synchro Positioner On Synchronizer Assembly (Typical) Courtesy of FORD MOTOR CO.
Fig. 4: Positioning Synchronizer For Installation Courtesy of FORD MOTOR CO. 2. Rotate sychronizer assembly so that synchro positioner is 60 degrees counterclockwise of crankshaft centerline before inserting synchronizer assembly into engine. See Fig. 4 . 3. As synchronizer is inserted into engine, synchronizer will rotate. When seated, synchronizer electrical connector should be located in original position.
CAUTION: If CMP sensor electrical connector is not positioned correctly, DO NOT reposition connector by rotating synchronizer. This may cause fuel system to be out of time with the engine, causing possible engine damage or an engine misfire. Remove synchronizer and reinstall. See step 3 . 4. Install hold-down clamp and tighten bolt to specification. See TORQUE SPECIFICATIONS . Install CMP sensor to synchronizer and tighten to specification. Ensure CMP sensor electrical connector is in original position. Reconnect wiring to CMP sensor. Connect negative battery cable.

98 wrangler shuts off and won't start intermittently. Codes are P1594, 0320, 0463 & 1391. Do I change the crank senor, cam sensor or fuel filter/regulator??

(this is for others who may be viewing this problem)
P1594 = charging system voltage is too high
P0320 = crankshaft position sensor (CKP)/engine speed (RPM) sensor-circuit malfunction
P0463 = fuel level sensor circuit, high output
P1391 = intermittent loss of CMP (camshaft position) or CKP (crank position) sensor

Probably start with changing the crank sensor. But keep in mind that the high charging system voltage may be causing the other electrical sensor problems. The voltage regulator (probably located internally in the alternator) is not regulating voltage properly. So changing the alternator may be needed as well. Price the parts and start with replacing the less expensive first.
