Volvo V50, VIN YV1MW753152104530, engine D4204T. Diagnostic shows error code ECM-1934 Vehicle speed signal missing. Does it mean that there is separate speed/odometar sensor for ECM, since speedometer and odometer works? If so, where to look for that sensor? Regards, Nenad Danicic

Question editerd for clarity.

Question moved to model category, however, there are 3 engine sizes for that model.

The engine control module (ECM) checks the signal from the by-pass valve in the thermostat housing. The diagnostic trouble code (DTC) is stored if the signal from the by-pass valve is too high. The fault is diagnosed by the engine control module (ECM) when the ignition is on.
Check for short-circuit to supply voltage in the signal cable.

Most likely this is ADM (Additive Dosing Module) error in diesel engines with DPF. Check in hidden diagnostic menu if ADM is reporting DTCs.

I hope this helps and is what your looking for... good luck

Ford P0715 OBD-II Trouble Code Definition:
P0715 Input Shaft Speed Sensor Circuit Malfunction
P0715 Ford OBD-II Trouble CodeDescription:
OBD Trouble Code P0715 Input/Turbine Speed Sensor "A" Circuit What does the code mean? OBD-ii Code P0715 definition:
The input speed sensor detects the primary pulley revolution speed and sends a signal to the Transmission Control Module (TCM) and Engine Control Module (ECM). Symptoms Sumptoms of OBD code P0715
- Engine Light ON (or Service Engine Soon Warning Light) - Possible shifting problems Causes Causes of the OBD-II code P0715
- Transmission speed sensor circuit is open or shorted. - Poor transmission speed sensor circuit connection - Faulty transmission speed sensor The Error code is generally activated on detection of the following conditions: Diagnostic Trouble Code (DTC) P0715 is detected when TCM or ECM does not receive the proper signal from the sensor. Solutions

Check battery voltage (engine off= 12V; engine on=14.4V), then check fuses, then connect with Volvo diagnostic tool and check for error codes.

Millage service message can be reset without dealer tools. However this is an error message. You need diagnostic tool to check the error code. All you can do right now is to enter hidden menu and check which module is reporting issue (DTC code).

OBD Code 12 - No Distributor Reference Pulse (Diagnostic Test Active) The Engine Control Module-ECM uses the distributor reference pulse to calculate the engine speed. On newer engines, the Crank Shaft Position Sensor performs this function.

Symptoms:

• When flashing the Check Engine Light to read codes, code 12 will always display first, indicating the diagnostic system is active
  
• The engine will not run with a "hard" code 12 set
  

Common Problems:

• Chances are you will never need to diagnose a code 12. Rather, the problem would be a crank, no-start condition.
• If code 12 does not flash, that would indicate a communication problem with the ECM.
• Code 12 does not show when reading codes with a scan tool. If there is a communication problem, the scan tool will let you know.

OBD Code 46 - Pass-Key II System Error - Circuit out of Frequency Range The ECM receives a signal from the Pass-Key module. When the correct signal is received, the ECM will allow the engine to start and run. Please review the RepairPal article on the GM Pass-Key Anti-theft systems for more information.

Symptoms:

• Engine may not start

Common Problems:

• Faulty ignition lock cylinder

OBD Code 43 - Knock Sensor error The ECM receives a signal from the Knock Sensor based on the amount of engine ping detected. The ECM uses information from this sensor to help calculate fuel delivery and spark timing.

Symptoms:

• Engine ping
• Lack of power

Common Problems:

• Faulty Knock sensor
• Poor connection at Knock sensor

OBD Code 55 - End Test.


Hope ehit help (remember comment and rated this).

Take the vehicle to Auto Zone or O'Reilley's auto parts of any local auto parts store that offers to read stored codes for free and they will be able to tell you exactly what codes are showing and what they mean for free. In addition you will be able to by the repair parts while your there.

Code 1633 is not a manufactures code, it is a genetic one, and is not as specific as a volvo code.
The best thing to do is take it to a volvo shop and get the specific code.
I did find a meaning for it------- speed signal missing or absent.
That could mean either a wheel speed sensor, or a vehicle speed sensor is at fault, that's why you have to get the specific code.

810 neutral check, incorrect connection

Check the transmission and control module connectors. Check for contact resistance and oxidation according to Checking wiring and terminals. Permanent faults

1132 front o2 sensor signal too high
1618 dtc is in another module
Volvo does not provide information regarding DTC P1633 for many of their models.
However, it has been reported that various Volvo engine control modules will produce this code. The code is associated with a missing or inaccurate vehicle speed signal from the ABS control module and may be accompanied by DTC P0722 or P1618.

Possible causes:
- Defective vehicle speed signal to the ABS control module
- CAN connection problem
- Defective ABS control module
- Defective engine control module

Manufacture codes associated with this P code may include ECM-510f, 530d.
