Pinpoint Test I : The Temperature Gauge Is Inoperative
WARNING: This page is about a different car, the 2018 Ford EcoSport. However, it is still accessible from the selected car via links, so may be relevant.
- Normal Operation and Fault Conditions
See Temperature Gauge. REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .
If the IPC does not receive the engine coolant temperature message or if the engine coolant temperature message is deemed invalid from the PCM for more than 5 seconds, the IPC defaults the temperature gauge to cold (C).
Possible Sources
- Communication concern
- PCM
- GWM concern
- IPC
- I1 PERFORM THE IPC (INSTRUMENT PANEL CLUSTER) SELF-TEST
- Using a diagnostic scan tool, perform the IPC self-test.
- Check for recorded Diagnostic Trouble Codes (DTCs) from the IPC self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to DTC Chart: Instrument Panel Cluster (IPC) No GO to I2 - I2 PERFORM THE PCM (POWERTRAIN CONTROL MODULE) KOEO (KEY ON, ENGINE OFF) SELF-TEST
- Using a diagnostic scan tool, perform the PCM KOEO self-test.
- Check for recorded Diagnostic Trouble Codes (DTCs) from the PCM self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to ELECTRONIC ENGINE CONTROLS (1.0L) or refer to ELECTRONIC ENGINE CONTROLS (2.0L) No GO to I3 - I3 CHECK THE GWM (GATEWAY MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, check the GWM Continuous Memory Diagnostic Trouble Codes (DTCs).
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes No GO to I4 - I4 PERFORM THE TACHOMETER ACTIVE COMMAND USING THE SCAN TOOL
- Using a diagnostic scan tool, view the IPC Parameter Identifications (PIDs).
- Select the IPC temperature gauge (ENGCOOLNT) PID.
-
NOTE: Make sure to set the scan tool to 0 or full cold before beginning this step.
Command the temperature gauge on and off while monitoring the temperature gauge.
Does the temperature gauge start at cold (C), move to full hot (H) and return to cold (C)?
Yes Refer to PCM GUIDED ROUTINE TESTING No INSTALL a new IPC. REFER to: Instrument Panel Cluster (IPC) .
