Symptoms of a Faulty Cylinder Head Temperature
Sensor
2
The cylinder head temperature sensor is an
electronic engine management sensor found on many
modern cars nowadays.
3
The cylinder head temperature sensor measures the
temperature of the engine cylinder head.
4
The computer uses this temperature measurement to
calculate timing and fuel for maximum engine
performance and efficiency.
5
The cylinder head is similar in purpose to the
coolant temperature sensor, but it is more
accurate due to the construction operation of
the sensor.
6
When the cylinder head temperature sensor has an
issue, it can negatively affect the performance
of the vehicle.
7
Here are the symptoms of a failing cylinder
head temperature sensor.

• Long cranking time

• Engine performance problems
• Check engine light illuminates
• Replacing the cylinder head temperature sensor

8
Long cranking time
9
One of the first symptoms commonly experienced
with a bad or failing cylinder head temperature
sensor is a long cranking time.
10
The signals provided by the cylinder head
temperature sensor monitors an important
parameter, and when it malfunctions the cranking
time gets extended.
11
If you notice the vehicle takes a longer
cranking time when starting, then this is an
indication that the cylinder head temperature
sensor is giving a faulty reading.
12
Engine performance problems
13
Another symptom of a potential issue with the
cylinder head temperature sensor is engine
performance gets affected.
14
The temperature of the cylinder head is a very
important signal used in engine calculation, thus
any issues with them affect the engine's
performance.
15
A malfunctioning cylinder head temperature
sensor may cause issues like a decrease in power,
acceleration, and fuel economy.
16
The performance issues are slightly noticeable in
the beginning, but gets worse with the passage of
time.
17
Check engine light illuminates
18
The check engine light gets illuminated when
there are some issues with the cylinder head
temperature sensor.
19
Replacing the cylinder head temperature sensor
20
First the cylinder head temperature sensor is
verified for replacement, then the rubber head
seal connector are removed to access the sensor.
21
The defective cylinder head temperature sensor is
removed with a deep well socket to unscrew the
sensor from the cylinder head.
22
Then the new cylinder head temperature sensor is
installed in the head and tightened to
specifications.
23
The newly installed cylinder head temperature
sensor is tested for operation using a scanner.
24
Finally
25
The cylinder head temperature sensor is an
important component of the vehicle should be
inspected regularly for issues.
26
If you notice any of the above-mentioned
symptoms, then it is an indication that the
cylinder head temperature sensor has
malfunctioned.
27
You should never be complacent in dealing with
the issue and should take your car to an
automotive repair shop to replace it immediately.
