That definition means that for some reason the PCM is seeing a low input from the ECT sensor. That could be sensor problem, a wiring problem, or a PCM problem, but the most likely problem is that the truck is actually running too cold. That could be a stuck open thermostat, or an incorrect temperature thermostat installed.

code 15 is coolant temperature circuit {low temperature} Im also trying to source exactly what this problem equates too as im currently trying to help a friend with the same code problem on his 1994 astro awd !

Have you checked your temperature? There are two sensors one is for coolant level, and other is for temperature. First make sure your not over heating, then disconnect your coolant level sensor located on your coolant tank, and disconnect it. If light goes out, this may be your problem. Although I am not one hundred percent sure this would work as way of testing, because the circuit for level sensor may only come on when circuit is broken. This means you would have to do a jumper wire in the plug for level sensor, and see if light goes out.

possibly air intake filter, and check radiator water and coolant if it is dirty drain flush and clean the radiator and put in new coolant.

Temperature gauge reads signals off the coolant temperature sensor. It can also point to a faulty thermostat. If your car runs rough in cold, idles rough and uses up more fuel then coolant temperature sensor is your problem. They are normaly a cheap and easy diy to do.

Overheating is due to, well, the coolant in the cooling system getting too hot. In a normally operating engine, this should never be a problem. First, check that the coolant level is correct. If it is correct, I would suspect a problem with the thermostat. When the engine is cold, the thermostat closes off coolant flow through the engine until the coolant reaches a pre-determined temperature. When that temperature is reached, the thermostat opens to allow the coolant to circulate at that exact temperature. Thermostats are known for failing and either not opening or not opening enough at that pre-determined temperature. This causes coolant to get trapped too long in the engine coolant chambers, heating it beyond limits, causing the engine temperature to increase and possibly overheat. If my Maxima was overheating, I would check the coolant levels and then possibly replace the thermostat. It usually is no more complicated than that.

your coolant is low.......this happens when you are idle and then once you start moving it goes down......fill your coolant to the top and itl fix this problem

I've been having the same problem, did you find the location yet?

Check the coolant level. If it's not a problem, then it can be contaminated radiator, bad water pump, check leakage.

Either there's a problem with your sensor, or there's a problem with your thermostat, and it's giving a false reading. Your engine temp may actually be high, as well - what you see on the gauge is the temperature of the coolant, not of the block itself.

A bad coolant temperature sensor is one thing that could cause an idling speed problem with a Peugeot 406. There could also be a problem with the idle control valve.

An open thermostat would keep the engine from heating up to normal operating temperature. The sensors effected can only report what they sense. The "check engine" light may throw a code like "P0116" (engine coolant temperature circuit range/performance problem).

The Engine Coolant Temperature in the Engine is higher than it should be. Check your radiator coolant level - also your radiator may be clogged or thermostat may be stuck.

If the temperature goes up and down and the coolant level is ok your thermostat is probably sticking. Replace the thermostat and you should solve the problem.

NOTE: this answer is describing the location of the engine coolant temperature sensor - NOT the coolant sensor in the reservoir that warns when the level gets too low.The coolant temperature sensor is located directly adjacent to the thermostat housing. The thermostat housing is what the upper radiator hose (toward the right side of the engine compartment) connects to. You do not have to replace the reservoir to replace this part, but leaky coolant reservoirs are a common problem on this model.

I had a similar problem with mine.... temperature gauge would shoot up after 10 minutes of driving and all the coolant would be gone... started watching the tail after replacing the coolant and saw white smoke... found out later it was a crack in the cylinder and it was burning coolant... this may not be your problem, but it mite help...

BDTC P0128 Engine Coolant Temperature (ECT) Below Thermostat Regulating Temperature " I have seen this several times this week alone. All three times I replaced the coolant temp sensor and it fixed the customers problem. john f.

i have a 95 impreza and i just got the same dtc ( po115) along with po114 wich was my 02 sensor. So most likely the fuel loop problem is being caused by the coolant sensor and once that is replaced the other problem should subside. Similar to my 02 sensor dtc, wich i believe is being caused by the excess gas being used from the faulty coolant sensor

Diagnostic error code number 118 with high temperature input on a Audi A4 means that the engine coolant is not running at the right temperature. When the engine is cold, it should be warm, and when the engine is warm, the temperature should be cooler in the engine. The problem could be with the Engine Coolant Temperature sensor or the vehicle could be low on fluid.
