Are 2012 Ford Focus hatchbacks good cars?
An available super fuel economy package (SFE) boosts highway fuel economy to 40 mpg. Reviewers agreed that the Focus has a smooth ride, sharp steering and handles exceptionally well for a compact car, tackling corners with confidence. The Focus is available in sedan and hatchback body styles.
How does heat coolant work in a Ford Focus?
Heat coolant is released to the air in the radiator as air is pulled across it’s cooling fins by the electric fan. To keep the engine cool, the fans must work properly and the coolant must flow freely through the engine. Allow the engine to cool completely.
How to troubleshoot overheating in a Ford Focus?
Clip the test light to the negative battery terminal and probe the fan’s electrical connector. One of the terminals in the connector should cause the test light to come on when it is touched with the probe indicating power is being supplied to the fan. Switch the test light to the positive battery terminal and touch the terminals in the connector.
Where to check coolant level in Ford Focus?
Check the coolant level in the expansion tank located on the passenger side of the engine compartment. The tank is clearly marked low and full. Add coolant as needed. Remove the pressure cap from the top of the expansion tank and attach the pressure tester to the expansion tank in its place.
What causes the test light to come on on a Ford Focus?
One of the terminals in the connector should cause the test light to come on when it is touched with the probe indicating power is being supplied to the fan. Switch the test light to the positive battery terminal and touch the terminals in the connector.
Why is my Ford Focus overheating at 12 V?
It became apparent that no control signal was present on the fan control wire, which remained fixed at 12 V regardless of temperature or scan tool intervention. I had a number of points to consider: The cooling fan fault code: P0480 Fan 1 Control Circuit Permanent stored. The cooling fan will function when powered independently.
What’s the coolant temp on a Ford Focus?
Live data inevitability confirmed that the coolant temperature was rising above 100°C with no intervention from the cooling fan. The cooling system pressure felt normal when squeezing the coolant hoses and monitoring activity within the expansion bottle.
What’s the fan frequency on a Ford Focus?
In figure 6 you can see how the fan control wire is pulled from 12 V to ground at a frequency of approximately 110 Hz. This is identical to the frequency measured with the bias voltage while the fault was apparent.
What is the bias voltage on a Ford Focus?
More importantly, during the component test, the bias voltage is pulled to ground at a frequency of approximately 110 Hz. This was proof enough to me that the PCM was at least attempting to control the cooling fan, confirming the integrity of the PCM and control wire – or did it?
