Code P0118

[rasmeidirt]

My 96' Sidekick Sport keeps poping the code P0118 engine coolant temperature sensor circuit high voltage. The engine revs up to 2500 RPM and take a long to get down. What is causing this??

118 , means  he ECT sensor is bad. ( stuck crazy too cold frigid)


Thanks. It is still OEM ECT. Never touched it or changed it. A new replacement would be OK??

118 , means  he ECT sensor is bad. ( stuck crazy too cold frigid)
1: disconnected connector to it (its behind top rear of engine head on water outlet port) 1.8L DOHC
2: pins on it are  rusty.
3: wrong ECT installed
4: wires to it cut, damaged
5: or is just BAD ECT.


118 means it reads 5vdc,  that means reads and open circuit,  on hot engine it read 203F.  (200 to 300 ohms hot it reads, cold it read.  70F 2350 ohms. room temp.

118 means the temperature reading computes to -55F degrees or more, cold,  means the sensor is reading dead open,

if the pins are damaged , it will read wrong, best is to look first.  the coolant loop must be breached to change it, drain out 1/2 gallon of coolant.
any sensor shown on rockauto works 1.8L your year card. sport.  (rock shows many brands, what is sold in your world, IDK)
most have dual sensor there, one for dash gauge ,one for ECU,  of both fail , that implies the ground to the sensor is cut. ( 3wire sensor)? is dual.
as pure usual stores show many sensors, and wrong, for J18,  there is only one sensor that works here,  
suzuki p/n 13650-50G01.
has 3 terminals not 1, not 2,  but 3, and 3 only for J18 engine 1996
if you had looked a yours first behind the head you see 3 pins in the sensor and not damage. first.

again IM NOT TELLING YOU are anyone ever to buy from ROCK only that the have lots of choices. there, and sadly  have. 2 wire sensors for G15 mixed in with J18 engines,
the single pin sensor is also for G16 engines, only, so.... this is common in most stores, here.
they dont know that VIN engine code 2 means J18, it fools them.

The only parts that is correct is 50G01.
the maker SMP makes this;.

sMP: is hUGE maker, of fine parts.

Thank you very much for the reply.

What I did!

Disconnect the ECT coupler, the three pins are there solid, no rust. Turn the key on and view the coolant data on the scan tool, the value is -40F. I try to sandpaper the three pins and spray the WD-40 on both the pins and the coupler. Erase the code in the scan tool and start the car. The engine runs smoothly. Leave it that way at the moment to see what happen next???

Driving today. The code does not return! It was the same for my TPS code. Never throw away your OEM Suzuki sensors!!

If you ever remove any sensor WITH key on, the PCM sees that gross error and stores  that  ERROR in the PCM memory.  and then must be OBD2 scan tool reset, or drive many long hard driving cycles to erase the DTC error you created.
never use sand paper to pins, it wipes out the special plating on the pins wrecking them.,  just use electrical cleaners. ok?
learn to respect the pin plating.  is best.  clean them with extra special care. or it will go far far worse
and respect too that suzuki does not sell ever those connectors, (long long ago yes, the full harness) but not now.  double, respect the pins, OK?  
WD40  MU (Multipurpose ) is oil, Id never oil my pins.  I use electrical contact cleaners real not this  MU  WD40.. (blue and yellow can)


w40 MU is for rusty screws or as the name states water dispersal WD (it is an oil )  buy a can of electrical cleaner.
OK I now see WD40 brand now sells that too (sliver black can),  so W40 now means NOTHING, , so  that is cute trick now.

I use CRC electrical contact cleaner.  or any seen here

Thanks. Well, stuff like that is not available here! People don't use that. We have grease, but we don't have de-electric grease. Buy them online, they don't ship to here so what!

Just sandpaper it a little since it is not enough space out there.

It was just like the TPS code. I did the same and the code does not return until today.
