How to Fix P1183 KIA Code?

Start by checking the “possible causes” listed above. Visually inspect the corresponding wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector pins.

Possible Symptoms

Engine light on (or engine service warning light soon)

P1183 KIA Meaning

The rail pressure regulator, which is installed in the high-pressure pump, controls the rail pressure by regulating the amount of fuel supplied to the common rail. The ECM performs a service control of the rail pressure regulator to maintain the rail pressure at the target rail pressure based on the engine’s current load condition.
As the rail pressure regulator service increases, more fuel flows into the common rail, so the rail pressure increases.
When the rail pressure regulator operation stops due to the rail pressure regulator power supply being cut off, the maximum amount of fuel flows to the common rail when the passage inside the regulator is fully open.

Possible Symptoms

Engine light on (or engine warning light soon in service)

P1183 LINCOLN Meaning

The Engine Oil Temperature (EOT) sensor is a thermistor device in which resistance changes with temperature. The electrical resistance of a thermistor decreases as temperature increases and resistance increases as temperature decreases. The variable resistance affects the voltage drop across the sensor terminals and provides an electrical signal to the Engine Control Module (ECM) corresponding to the temperature.
Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that the change in the passive sensor’s resistance causes a change in the total current flow.
The voltage that drops across a fixed resistor in series with the sensor resistance determines the voltage signal at the ECM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.
The EOT sensor measures the engine oil temperature. The sensor is typically screwed into the engine oil lubrication system. The ECM can use the EOT sensor input to determine the following:
– On Variable Camshaft Timing (VCT) applications, the EOT input is used to adjust VCT control gains and camshaft timing logic.
– The ECM can use the EOT sensor input in conjunction with other ECM inputs to determine oil degradation
– The ECM can use the EOT sensor input to trigger an engine shutdown. To prevent engine damage due to high oil temperature, the ECM has the ability to trigger an engine shutdown. Whenever the engine speed exceeds a calibrated level for a certain period, the ECM begins to reduce power by disabling engine cylinders.

– The ECM can use the EOT sensor input to trigger an engine gradual shutdown. To prevent engine damage due to high oil temperature, the ECM has the capability to trigger an engine gradual shutdown. Whenever the engine speed exceeds a calibrated level for a certain time, the ECM begins to reduce power by disabling engine cylinders.
