1998 S70: No spark Camshaft position sensor cable shows 12 ...

No spark camshaft position sensor cable shows 12 vdc on pin 2 and 3. (chilton manual says pin 2 should read 5 vdc) i have replaced 2 ecus on this car in the past 3 years or so. When rthey have failed I have had the same symptom no spark etc. i have read that failed ecus are rare. I think I may have blown another one. questions: do I have another bad ecu? how can I tell the ecu is bad without buying another used one? can a Volvo dealership test it? if it's bad what is causing their failure?

Where does the camshaft position sensor go on a 1999 Volvo S70?


At the rear of the cylinder head on the exhaust side camshaft.

1 Answer

No spark or fire to plugs


Sounds like a bad crank position sensor or a bad camshaft position sensor.... If the sensors can't tell the ecm where the position the crankshaft or camshaft is, the ecm won't know when to send a spark. So the ecm won't send any spark.

Description & Operation

The Camshaft Position Sensor (CMP) is a variable reluctance sensor that is triggered by a high point on the left-hand exhaust camshaft sprocket. The CMP sends a signal relating camshaft position back to the PCM which is used by the PCM to control engine timing.
The CMP sensor detects the position of the camshaft. The CMP sensor identifies when piston No. 1 is on its compression stroke. A signal is then sent to the PCM and used for synchronizing the sequential firing of the fuel injectors. Coil-on-plug (COP) ignition applications use the CMP signal to select the proper ignition coil to fire. The input circuit to the PCM is referred to as the CMP input or circuit. DTC P0340 is associated with this sensor.


Removal & Installation

3.0L (VIN S) Engine

  1. Before servicing the vehicle, refer to the Precautions section.
  2. Disconnect the battery ground cable.
  3. Remove the electrical connector.
  4. Remove the bolt and the CMP sensor.
  5. To install, reverse the removal procedure.

  1. Before servicing the vehicle, refer to the Precautions section.
  2. Disconnect the battery ground cable.
  3. Remove the pin-type retainers and remove the accelerator cable snow shield.
  4. Detach the spark plug wire retainer.
  5. Detach the wiring harness from the intake manifold support.
  6. Release the fuel charging wiring harness from the valve cover studs. Position the wiring harness away from the camshaft position sensor.
  7. Disconnect the electrical connector.
  8. Remove the screws and the CMP.
  9. To install, reverse the removal procedure.
    NOTE Make sure that the fuel charging wiring harness is fully secured to the valve cover studs.

Fig. Testing the VPWR circuit of the CMP sensor

  1. Check voltage between the camshaft position sensor terminals PWR GND and CID.
  2. With engine running, voltage should be greater than 0.1 volt AC and vary with engine speed.
  3. If voltage is not within specification, check for proper voltage at the VPWR terminal.
  4. If VPWR voltage is greater than 10.5 volts, sensor may be faulty.

Fig. Camshaft Position Sensor Connector

  1. Before servicing the vehicle, refer to the Precautions section.
    WARNING Use only a high-impedance multimeter, otherwise damage to the PCM and/or sensors can result.
  2. With the key OFF , disconnect the CMP sensor harness connector.
  3. Measure the resistance of the CMP sensor.

    3.0L Engine: 250-1000 ohms
  4. If the resistance measured is outside the limits given, replace the CMP sensor.

1993 ford taurus, replaced all starting and charging componets still no spark to plugs. Checked all fuses and all fusible links. Replaced key switch, ignition switch,neutral safty...


The camshaft position sensor sends a signal to the PCM, powertrain control module. The PCM then determines spark plug firing. Could be the camshaft position sensor.

1996 is all I have
Camshaft Position (CMP) Sensor 3.0L (2V) Engine
The camshaft position sensor (CMP sensor) (12126):
  • is a single Hall-effect magnetic switch activated by a single vane which is driven by the camshaft (6250).
  • provides camshaft position information which is used by the ignition coil (12029) and the powertrain control module (PCM) (12A650) for fuel synchronization.
3.0L (4V) Engine
The camshaft position sensor (CMP sensor) (6B288) is:
  • a variable reluctance sensor.
  • triggered by the high-point mark on the LH exhaust camshaft sprocket (6256).
-----------------
3.0L (2V) Engine
SPECIAL SERVICE TOOL(S) REQUIRED Description Tool Number Syncro Positioning Tool T95T-12200-A
sth~us~en~file=ani_caut.gif~gen~ref.gif CAUTION: Prior to removal of the camshaft position sensor (CMP sensor) (12126), set cylinder No.1 to zero degrees top dead center (TDC) of compression stroke. Then note the position of the camshaft position sensor electrical connector. The installation procedure requires that the connector be located in the same position.
Removal
  1. Disconnect battery ground cable. Refer to Section 14-01 .
  1. Disconnect engine control sensor wiring connector from camshaft position sensor.
  1. Remove camshaft position sensor retaining screws and camshaft position sensor from camshaft position sensor housing.
  1. If removing camshaft position sensor housing from the cylinder block (6010), proceed with Removal Step 5. If not removing camshaft position sensor housing, proceed to installation Step 6.
  1. Remove hold-down clamp (bolt and washer assembly).
  1. Remove camshaft position sensor housing from cylinder block.
Installation
  1. sth~us~en~file=ani_caut.gif~gen~ref.gif CAUTION: A special service tool such as Syncro Positioning Tool T95T-12200-A must be obtained prior to installation of the replacement camshaft position sensor. Failure to follow this procedure will result in improper camshaft position sensor alignment. This will result in the fuel system being out of time with the engine, possibly causing engine damage.
    Attach Syncro Positioning Tool T95T-12200-A as follows:
    1. Engage camshaft position sensor housing vane into the radial slot of the tool.
    1. Rotate tool on camshaft position sensor housing until tool boss engages notch in camshaft position sensor housing.
  1. Pre-lubricate synchronizer gear with engine oil meeting Ford specification ESE-M2C123-A prior to assembly.
  1. Install camshaft position sensor housing so that drive gear engagement occurs when arrow on locator tool is pointed approximately 75 degrees counterclockwise from the rear face of the cylinder block. This step will locate camshaft position sensor electrical connector in the pre-removal position.
  1. Roatate Syncro Positioning Tool T95T-12200-A clockwise slightly. This will engage oil pump intermediate shaft. Push downward while adjusting Syncro Positioning Tool T95T-12200-A until the Syncro Gear engages the camshaft gear.
  1. When synchronizer flange is fully seated against block, the installation tool should be facing counterclockwise of engine centerline approximately 33 to 45 degrees.
  1. Install hold-down clamp (washer and bolt) and tighten bolt to 19-30 Nm (14-22 lb-ft).
  1. Remove Syncro Positioning Tool T95T-12200-A.
  1. sth~us~en~file=ani_caut.gif~gen~ref.gif CAUTION: If camshaft position sensor electrical connector is not positioned properly, DO NOT reposition the connector by rotating the camshaft position sensor housing. This will result in the fuel system being out of time with the engine, possibly causing engine damage. Remove the camshaft position sensor housing and repeat installation procedure, beginning with Step 1.
    Install camshaft position sensor and retaining screws. Tighten screws to 1.5-4.0 Nm (13-35 lb-in).
  1. Connect engine control sensor wiring connector to camshaft position sensor.
  1. Connect battery ground cable.
