SOURCE: engine code p0115

The Engine Coolant Temperature (ECT) sensor is located in the coolant passage of the cylinder head. The ECT sensor is a variable resistor whose resistance changes as the temperature of the engine coolant flowing past the sensor changes. When coolant temperature is low, sensor resistance is high; when coolant temperature is high, sensor resistance is low. The Engine Control Module (ECM) checks ECT sensor voltage and uses the information to adjust fuel injector pulse width and ignition timing. When the temperature sensed is very cold, the ECM enriches the fuel mixture and advances ignition timing. As coolant temperature rises, the ECM reduces the amount of enrichment and timing advance. ad5a8e2.jpg P0115 is set when the ECM doesn't see this resistance (usually an open circuit) which usually means the sensor is burned out when there's nothing wrong with wiring and connections between the sensor & the ECM.

SOURCE: engine coolent temp circuit high input. what is

that code means the coolant temp sensor has an open circuit.might be unplugged or bad or a wire has broken somewere for it.high input means the compuer is seeing something real close to 5 volts from the sensor wich is the reference voltage.if it were shorted to ground it would be different code but would say low input

This obd computer code po115 what does this mean?

this indicates a open or short-circuit in the engine coolant temperature sensor circuit......

so, assuming that there has been no wiring work going on, or other problems...i would be replacing the coolant temp sensor, as required.

Year 2001 XG300 P0115, P1159, P1191, P1193, P0115

P0115 - Engine Coolant Temp Sensr - open/short
P1159 - Variable Intake Motor Malfunction

P1191/P1193 Limp Home Valve - Low RPM

First, clean the throttle body and check for anything which might obstruct AIR FLOW to it.

The P1159 is the Variable Intake Motor Malfunction. this motor is either 'OPEN'... or 'CLOSED' position. It is located on/in the intake manifold (plenum) and is only opened when cruising... it is closed at idle. If it sticks 'OPEN' is can cause drivability issues.

I need to details i received from engine codes: p0715 p0115 p01191 p01193

P0715 Input/Turbine Speed Sensor Circuit (transmission related)
P0115 Engine Coolant Temperature Circuit (fuel/air mixture related)
P1191 is a manufacturer-specific code related to fuel/air mixtures, as is P1193 - those will have to come from Hyundai.
