Where is located the 2006 ford focus of 2.0 engine coolant module temperature sensor


It doesn't have a coolant sensor it has a CHT, cylinder head temperature sensor. This type of sensor is much more precise measuring engine operating temperature.

I need the easiest possible directions to replace the coolant temperature sensor in my 1999 Chevy Lumina ltz 3.8 v6 car please.


The coolant sensor temperature is usually found just beneath the cylinder head, on the engine block.

You just disconnect the 1-2 wires and then undo it with a wrench.
The sensor will look like one of these:

Just be aware .. you may have TWO such sensors on your vehicle.

One sensor (usually with 3-4 electrical pins) is near the thermostat and works in conjunction with other sensors to regulate fuel/air according to engine temperature.

The other type of sensor is in the block near the cylinder head. It sends a signal to the temperature gauge on your dashboard ONLY. If your temp gauge constantly reads too hot or too cold .. this one is the culprit.25939754-r0ibht2u2t2rhetbyfvb2pry-5-0.jpg
If it's a running fault .. speed .. rough running .. fuel. It may look like this:

P1290 Ford
P1290 Ford - Cylinder Head Temperature Sensor Signal Less Than Self-Test Range

Repair Importance Level: 3/3

Repair Difficulty Level: 3/3 What does this mean?

http://engine-codes.com/p1290_ford.html

Forum Code

Possible causes

- Wrong thermostat

- Not at operating range

- Engine overheated

- Low engine coolant level

- Faulty Cylinder Head Temperature (CHT) sensor

- Cylinder Head Temperature (CHT) sensor harness is open or shorted

- Cylinder Head Temperature (CHT) sensor circuit poor electrical connection

What does this mean?

When is the code detected?

The Engine Control Module (ECM) detected the cylinder head temp below expected values

Possible symptoms

- Engine Light ON (or Service Engine Soon Warning Light)

P1290 Ford Description

The Cylinder Head Temperature (CHT) Sensor is mounted into the wall of the cylinder head and is not connected to any coolant passages. The CHT sends a signal to the Powertrain Control Module (PCM) indicating the cylinder head temperature. If the temperature exceeds 126°C (-258°F), the PCM disables four fuel injectors at a time. The PCM will alternate which four injectors are disabled every 32 engine cycles. The four cylinders that are not being fuel injected act as air pumps to aid in cooling the engine. If the temperature exceeds 154 °C (310°F), the PCM disables all of the fuel injectors until the engine temperature drops below 154°C (310°F).
