Codes

[Cali_Chris04]

If anyone is familiar with the CEL codes when scanned, could someone please tell me what the "P0118" code is? I had it scanned today by a friend with a Mini Cooper and that was the fault code but I don't know what it mean/is. All help is appreciated.:drama:

Ok, I got the source of the code, however, I don't know how to fix it. The code is for Engine Coolant Temperature Circuit High Input. Anyone have a clue as to how to fix?

16502/P0118/000280 - Engine Coolant Temperature Sensor (G62): Signal too High

Possible Symptoms



Difficulties with starting a cold engine.
Starting the engine when engine is warmish or warm, idle rpm immediately is 1200 - 3000 rpm.
RPM at idle is irregular.
With all engine temperatures idle rpm will often vary between 900 - 1000 rpm.
With engine warm (90 °C) the engine temperature suddenly drops (70 °C) and slowly comes back to 90 °C.
Bad acceleration during warm-up.
Diesel Engines: Glow plug indicator may be on for a longer than normal time or at ambient temperatures where it shouldn't come on at all.

Possible Causes



The electrical signal coming from G62 is too low
Wiring and/or connections faulty (short circuit?)
Engine Coolant Temperature Sensor (G62) faulty

Possible Solutions



Check wiring and connections
Check / Replace Engine Coolant Temperature Sensor (G62)

Special Notes



In many cars between MY 1995-2002 the G2/G62 had a bad reputation for failing often. The original G2/G62 sensor is black and the improved replacements are green.
