Signal too low
Status message
Note! The following is required to obtain the correct status message before the diagnostic trouble code (DTC) can be read:
- Ignition on.
- Wait approximately 30 seconds.
- Read off the status of the diagnostic trouble code (DTC).
Is the status permanent?
Yes - Checking oil temperature sensor signal cable
No - Intermittent fault
-------------------------------------------------
Checking oil temperature sensor signal cable
- Ignition off.
- Disconnect gray 2-pin transmission connector. For further information about connectors, see Transmission connectors Transmission Connectors.
Connect an ohmmeter between the gray 2-pin transmission connector terminal 2 (transmission side) and transmission housing.
Does the ohmmeter read infinite resistance?
OK - Checking oil temperature sensor resistance
Not OK - Checking for a short-circuit
-------------------------------------------------
Checking for a short-circuit
Check cable between oil temperature sensor and gray 2-pin transmission connector terminal 2 for a short-circuit to ground according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault.
Was a fault detected?
Yes - Verification
No - Replacing component
-------------------------------------------------
Checking oil temperature sensor resistance
- Ignition off.
- Gray 2-pin transmission connector disconnected.
Connect an ohmmeter between the gray 2-pin transmission connector terminals 1 and 2 (transmission side).
Compare the temperature below with the transmission temperature at the oil temperature sensor.
Does the ohmmeter show correct value? (See table)
Yes - Checking for a short-circuit
No - Replacing component
-------------------------------------------------
Checking for a short-circuit
Check cable between gray 2-pin transmission connector:
- terminal 2 and control module #34 (Fenix 5.1)
- terminal 2 and control module #33 (EMS 2000)
for a short-circuit to ground according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault.
Continue - Verification
-------------------------------------------------
Replacing component
Try a new oil temperature sensor according to Replacing oil temperature sensor Service and Repair.
Continue - Verification

Verification
Hint: After repairs have been completed they must be verified as follows to ensure that the fault has been eliminated:
- Ignition off.
- Reconnect the connectors, reinstall components etc.
- Ignition on.
- Wait approximately 30 seconds.
- Read off the status of the diagnostic trouble code (DTC).
Is the status intermittent?
Yes - VERIFIED
No - VERIFICATION FAILED

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
Do you want to exit fault-tracing?
Yes - Exit fault-tracing
No - Attempt New Test

Intermittent fault
Signal too low. Intermittent fault
Intermittent fault
Check the cable between the oil temperature sensor and the control module:
- terminal 34 (Fenix 5.1)
- terminal 33 (EMS 2000)
for an intermittent short-circuit to ground according to Checking wiring and terminals. Intermittent faults Checking Wiring And Terminals. Intermittent Faults.

If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
