SOURCE: Cam Shaft Sensor Problems

Had the same problem before on my 04 Neon SXT...camshaft sensor is on left side of engine block, take out the battery and to the left of it (face car) is the camshaft position sensor. To change it you'll have to move a few hoses but its plan to see there on the left side of the engine...pretty easy remove and replace. Fixed my problem of car not going above 2k RPM when i replaced the sensor.

SOURCE: O2 sensor bank1 sensor 1 where is it located on

prev.gif next.gif Oxygen Sensor I think that bank1 sensor1 stands for the upstream o2 sensor vs. the sensor2 which is the downstream o2 sensor. Both the 4 cyl. and 6 cyl. employ 2 o2 sensors.

If you get it wrong, changing both might be a good idea.
Removal & Installation 2.4L Engine NOTE: These engines use 2 heated oxygen sensors.
Upstream HO2S1 To Remove:
NOTE: If the engine temperature is lower than 120 °F (48 °C), the HO2S1 sensor may be difficult to remove. Excessive force could possibly damage the threads in the exhaust manifold.

  1. Disconnect the negative battery cable.
  2. Raise and safely support the vehicle.
  3. Disconnect the electrical connector from the sensor.
  4. Using an oxygen sensor removal tool carefully remove the heated oxygen sensor.
To Install:
  1. Clean the threads in the exhaust manifold with an 18 mm X 1.5 + 6E tap.
  2. If reusing the original sensor, coat the sensor threads with an anti-seize compound. New sensors come treated with anti-seize compound on the threads and do not require an additional coating.
  3. Install and tighten the sensor 20 ft. lbs. (27 Nm).
  4. Connect the electrical connector and install the wiring on the bracket.
  5. Lower the vehicle.
  6. Connect the negative battery cable.
Downstream HO2S2 To Remove:
NOTE: If the engine temperature is lower than 120 °F (48 °C), the HO2S 2 sensor may be difficult to remove. Excessive force could possibly damage the threads in the exhaust pipe.
  1. Disconnect the negative battery cable.
  2. Raise and safely support the vehicle.
  3. Disconnect the electrical connector from the oxygen sensor.
  4. Use an oxygen sensor socket to remove the sensor from the catalytic converter.
To Install:
  1. If reusing the original sensor, coat the sensor threads with an anti-seize compound. New sensors come treated with anti-seize compound on the threads and do not require an additional coating.
  2. Install and tighten the sensor 20 ft. lbs. (27 Nm).
  3. Connect the electrical connector to the sensor.
  4. Lower the vehicle.
  5. Connect the negative battery cable.
3.3L & 3.8L Engines NOTE: These engines use 2 heated oxygen sensors.
Upstream HO2S1 To Remove:
NOTE: If the engine temperature is lower than 120 °F (48 °C), the HO2S1 sensor may be difficult to remove. Excessive force could possibly damage the threads in the exhaust manifold.
  1. Remove the battery and battery tray.
  2. Disconnect the speed control vacuum harness from servo.
  3. Remove the cruise control servo and bracket. Place it out of the way.
  4. Disconnect the electrical connector from the oxygen sensor.
  5. Use an oxygen sensor socket to remove the sensor.

Remove the spark knock sencer on a 1997 dodge caravan


It depends on which engine your Caravan is equipped with. The knock sensor on the 2.4L engine is on the forward side of the engine just below the intake manifold. On the 3.3L and 3.8L engines it is on the forward side of the engine right next to the oil filter. All engines: Disconnect the electrical connector and unscrew the sensor from the engine block. Reverse procedure to install.

It should be noted that knock sensor failures are very rare on these vehicles. Most knock sensor fault codes for these engines are usually caused by mechanical problems that are creating "rattling" or "knocking" noises in the engine compartment. Things like bad pulley bearings, worn water pumps or loose timing components are most likely at fault. The knock sensor does not know the difference between vibrations caused by these type of failures and those that are caused by ignition ping. The fault code usually sets when the noise or "knock" is still present when the Powertrain Control Module (PCM) has retarded ignition timing as far as possible. If any knocking or rattling noises are present in the engine area, this should be diagnosed and repaired before replacing the sensor. (Otherwise you will only be wasting your money.)
