engine light on.
error code P0118.
Camry 2008
LD熄火的时候拧反了，变成点火了，之后启动就有问题，尤其冷启动多打几次才起得来
，熄火间隔短再启动就没问题。
看了一下说是coolant temp too high. 目前coolant fluid level正常.除了coolant
temp sensor之外还可能是其他问题么，和那次误操作有关么?

Possible causes
- Low engine coolant level
- Faulty Engine Coolant Temperature (ECT) sensor
- Faulty engine coolant thermostat
- Engine Coolant Temperature (ECT) sensor harness is open or shorted
- Engine Coolant Temperature (ECT) sensor electrical circuit poor connection
What does this mean? What does this mean?
When is the code detected?
An excessively high voltage from the sensor is sent to ECM.
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P0118 Toyota Description
The Engine Coolant Temperature (ECT) sensor is used to detect the engine
coolant temperature. The sensor modifies a voltage signal from the Engine
Control Module (ECM). The modified signal returns to the ECM as the engine
coolant temperature input. The sensor uses a thermistor which is sensitive
to the change in temperature. The electrical resistance of the thermistor
decreases as temperature increases.
