2001 300m overheating and leaking water got code po117

Question edited for clarity
Question moved to category.

Water leaks don't cause overheating unless there is no, or very little coolant..

Air locks cause overheating.
Failed water pumps cause overheating.
Blocked radiators cause overheating.
Stuck thermostats cause overheating.

code p 0117 refers to engine coolant temperature (ECT) sensor---circuit malfunction===causes ---coolant thermostat--wiring short to ground ---wiring short to positive---ECT sensor
check all the wires to the ect including the fan relay and fuses
you may have to reset the ECM using a scan tool but it depends on the damage done to the overheating engine
sever overheating generally results in blown head gasket or cracked head. if you let the engine shut itself down then the damage could be severe

PO117 refers to the coolant sensor. This should not cause the vehicle to not start/click. Make sure battery is fully charged. Maybe even try a boost. If the starter just clicks when the key is turned it may be getting bad. You can try tapping on the starter motor with a blunt object while holding the key in the crank position to see if it may start

EOBD II Error Code: P0117
Fault Location:
Engine Coolant Temperature (ECT) Sensor (G62) - Low Input
Possible Cause:
Malfunction Indicator Lamp (MIL) Triggered on first occurrence.
Coolant thermostat.
Wiring short to earth.
Engine coolant temperature (ECT) sensor.

EOBD II Error Code: P0340
Fault Location:
Camshaft Position (CMP) Sensor A (G40), Bank 1 - Circuit Malfunction
Possible Cause:
Malfunction Indicator Lamp (MIL) active.
Wiring from/to Camshaft Position Sensor (CMP) faulty.
Camshaft position (CMP) sensor faulty.
Timing misaligned.
Possible Solutions:
Check Wiring from/to Camshaft Position Sensor.
Check Camshaft Position Sensor.
Check Timing.

EOBD II Error Code: P0500
Fault Location:
Vehicle Speed Sensor (VSS) - Circuit Malfunction
Possible Cause:
Malfunction Indicator Lamp (MIL) Non Emission Fault - No warning light.
Wiring.
Vehicle speed sensor (VSS).
Engine control module (ECM).

here r your trouble code meanings:
1) p0123-throttle position sensor circuit, high input.
2)p0117-engine coolant temperature circuit, low input.
3)p0118-engine coolant temperature ciurcuit , high input.

You have a leak in the radiator, water pump, a hose, the heater or a head gasket. Check these and see if there is any water coming out of the exhaust or in the sump.
Take off the radiator cap, fill it right up to the neck, start the engine and warm it up. See if there are any bubbles in the top of the radiator, keep it topped up so there is no room in the top tank.
If there are continuous bubbles then there is a leak in the head gasket.

code po 1258 is an overheating code, need to check why u r overheating, start simple, do u have fluid, has it been changed , might need thermostat, how old is truck,. is there a leak anywhere.do pressure check on radiator and see if it leaks, check radiator temperature vs engine temperature. get a thermo scanner they work good. point and it reads how hot . if motor is hotter replace thermostat. check make sure oil level is good. get back to me let me know what u find..

check to see if the fan comes on if not there is a thermostatic switch that controls electric fan that is not working.
I have wired the electric fan into the key switch so it comes on with the key switch and goes off with the key.

PO117 - Engine Coolant Temperature Circuit Low Input
PO325 - Knock Sensor 1 Circuit Malfunction (Bank 1 or Single Sensor)

Do you have a coolant leak?
