How to replace 2000 z3 camshaft position sensor

A camshaft position (CMP) sensor is typically only used as a reference for sequential fuel injection into the cylinders by the powertrain control module (PCM). Technically speaking, the 2000 Honda Accord doesn't have a CMP sensor, rather a cylinder position sensor (CYP). This should not be confused with the crankshaft position sensor (CKP) which is primarily used for ignition timing. There are also two different engine options for the vehicle being the 2.3L 4-cylinder engine and the 3.0 V6 engine. Sensor locations will be different for each option so it's important to first identify which engine is in the vehicle. The CYP sensor for the 2.3L 4-cylinder engine is located inside the distributor and is not serviceable; the whole distributor would need to be replaced. The CYP sensor for the 3.0L V6 on the other hand is located behind the left camshaft pulley on the timing belt back cover and is a serviceable part.

The camshaft position sensor is mounted to the top of the timing case cover. The bottom of the sensor is positioned above the camshaft sprocket. The distance between the bottom of sensor and the camshaft sprocket is critical to the operation of the system.

Where is the camshafts on BMW z3 1997

A code P0340 could mean one or more of the following has happened:

• a wire or connector in the circuit could be grounded/shorted/broken
• the camshaft position sensor may have failed
• the PCM may have failed
• there exists an open circuit
• the crankshaft position sensor may have failed

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

If you have no spark, and you replaced the Crankshaft Position sensor, you may have a faulty Camshaft Position sensor, failed Timing Chain or stretched Timing Chain, or a faulty ECM. Since the Camshaft Position sensor doesn't cost much, I would start with that after checking the Timing.
Also, be sure to check the condition of the Connector going to the Crankshaft Position sensor and Camshaft Position sensor.

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.

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.

The camshaft sensor wouldn't explain the clattering noise. But a timing chain would explain both. Clattering from a loose chain and the camshaft sensor code from when the chain broke and the camshafts stopped turning.

2.0L 2.4L Removal The camshaft position sensor is mounted to the rear of the cylinder head.

Remove the negative battery cable. Disconnect the PCV hose and reposition Disconnect electrical connectors from the camshaft position sensor. Remove camshaft position sensor mounting screws. Remove sensor.Loosen screw attaching target magnet to rear of camshaft and remove magnet.
Instalation The target magnet has locating dowels that fit into machined locating holes in the end of the camshaft.
- Install target magnet in end of camshaft. Tighten mounting screw to 3 Nm (30 in. lbs.) torque. Over torqueing could cause cracks in magnet. If magnet cracks replace it.
- Install camshaft position sensor. Tighten sensor mounting screws to 12.9 Nm (115 in. lbs.) torque.
- Carefully attach electrical connector to camshaft position sensor. Installation at an angle may damage the sensor pins. - Connect the PCV Valve hose. - Connect the negative battery cable.
2.7L V6 Removal
The camshaft position sensor is mounted in the front of the head.

Disconnect electrical connector from sensor. Remove camshaft position sensor screw.
CAM Sensor Location 2.7L
Without pulling on the connector, pull the sensor out of the chain case cover.

Installation - Install sensor in the chain case cover and push sensor in until contact is made with the boss on the head. While holding the sensor in this position,install and tighten the retaining bolt to 12 Nm (105 in. lbs.) torque.
- Attach electrical connector to sensor.

Good luck and hope this helps

haynes should have a manual on this car, which will show the location of the cam pos sensor. check autozone or napa
