What happens when a coolant temp sensor goes bad?
If the coolant temperature sensor goes bad it can send a false signal to the computer and throw off the fuel and timing calculations. It is not uncommon for the coolant temperature sensor to fail and send a permanently cold signal to the computer. This will reduce fuel economy, and may hinder engine performance.
Can I drive with a bad temp sensor?
It is possible to drive a vehicle with a faulty coolant temperature sensor as the management system defaults to a static reading. A vehicles coolant sensor is a critical component used by the engine management system. It directly effects, cooling and fueling of the engine and therefore effects how the engine performs.
What happens when the coolant temperature sensor fails?
It is not uncommon for the coolant temperature sensor to fail and send a permanently cold signal to the computer. This will cause the computer to think the engine is cold, even when it is not, and as a result will use more fuel than necessary. This will reduce fuel economy, and may hinder engine performance.
What happens when cold start injector goes bad?
A leaky cold start injector may result in a reduction in engine performance and acceleration as a result of the disturbed air fuel ratio. In more severe cases, where a large amount of fuel is leaking into the manifold the vehicle may even experience stalling or misfires.
Where is the cold start injector in the intake manifold?
The Cold Start Injector is the responsible for supplying more fuel into the intake manifold for an easier start on cold temperatures. It is located in the middle of the upper intake manifold plenum.
How does a coolant sensor work on an engine?
Most coolant temperature sensors operate using electrical resistance to measure the temperature of the coolant. This signal is then sent to the computer so that changes can be made to the engine’s timing and fuel calculations for optimal performance, as engines require more fuel when they are cold, and less fuel when they are fully warmed up.
