coolant temp sensor, S13/S14.......are they the same? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

khilgers · 02-03-2008, 09:08 PM

I am going to replace the coolant temp sensor on my S14 SR motor and I was wondering if the one for the S13 SR is the same. Everywhere I have seen them for sale only states the S13 one as an option. I would assume that they are the same, but I don't like buying things based off of assumptions. Any help would be great appreciated.

Use a B14 SR sensor IIRC.

khilgers · 02-03-2008, 09:21 PM

I was hoping there was another coolant temp sensor I could use. B14 was the 95-99 sentra/200sx correct?

garagelu · 02-03-2008, 09:22 PM

depends which one....ecu CTS or gauge CTS

khilgers · 02-03-2008, 09:24 PM

Sorry I should have specified.

I NEED THE ECU COOLANT TEMP SENSOR

khilgers · 02-03-2008, 10:26 PM

anyone else? Time for sleep I'll check for more info in the morning.

*njd07* · 02-03-2008, 10:47 PM

just curious...why does yours need replacing??? is your check engine light on? or you just replacing to get better mileage?

khilgers · 02-03-2008, 10:52 PM

I'm replacing it to try to figure out if my fan controller is dead or if my CTS is bad.

*fliprayzin240sx* · 02-03-2008, 10:54 PM

If the ECU CTS is dead, your car will run like shit once the engine is warm.

Are you 100% sure. Can anyone else chime in on this?

garagelu · 02-04-2008, 03:18 PM

oh yea your car will run crazy rich if your CTS is bad. Your ecu will think you are in closed loop still and just keep dumping fuel.

And no I dont think the s13 CTS is the same is S14. I know that the USDM 91 sentra se-r CTS is the same as the s13 sr20 CTS. So you may want to try the B14 CTS as mentioned above. That should be the right CTS for you.

Go to the nissan dealer and find out if the B13 and B14 CTS have the same part number. Make sure they know its the se-r. This should give you a better clue.

use one from a s14 KA.

projectRDM · 02-04-2008, 04:02 PM

True, a bad CTS will signal the ECU to run the cold fuel map all the time, even when warm, running extremely rich and tripping to O2 to go into open loop. You can also test it by unplugging it, if the OEM electric fan is still wired in, the fan will turn on immediately, no matter the actual temp.

Is yours a red plug, or blue plug?

buku_points · 02-04-2008, 08:10 PM

since you guys are one the cts subject, i have a 98 s14 obd II,it threw a engine light for the cts, i changed it but still throws the light, it runs super rich,i have no mods and get worse mileage than a truck. what else could it be?

***S14DB*** · 02-04-2008, 08:26 PM

The connector? Thermostat?

buku_points · 02-04-2008, 09:06 PM

both are still good, but when i plug the connector into the cts thats when it boggs and smells like gas bad but if i unplug it doesnt smell as bad
