Just re-acquired my old 2001 BU. The temp gauge go not move off the the pin at the cold mark. Idle is a small high prefer the vehicle is in cold loop mode. The CEL has actually not come on. I perform not recognize if over there are any kind of pending password at this point. Automobile has 115K on it. I had the LIM gasket changed at 35K. I do not remember if I also had the t-stat replaced then or not. What room the specialists thoughts ~ above the cause of the temp gauge no working. Ns was thinking about replacing the t-stat just since of just how long it has been in the car. What around the temp sending out unit?
Tstat is a great start. Prefer others (actual experts, no me) have said before, tstat will certainly fail before the sensor, plus it"s a maintain item, so it"s good to replace it just because.(Welcome back to posting! )

While replacing the thermostat, it might not be a negative idea come swap the sending unit.Before ns did that, however, I"d loaned (or buy! ELM 327 Bluetooth OBD2 dongles can be had actually for under $20, Torque can be had actually for totally free for Android phones) a OBD2 scanner that have the right to read raw data streams (not just a code reader) and see what temp the ECU is seeing. If the sees something off the wall like -40, climate it"s the wiring or the sensor failed.Seeing what the ECU sees contrasted to using a non-contact thermometer ~ above the thermostat housing may likewise be instructive.OTGH - enough age, the thermostat may need to be replaced, and also while it"s acquired the coolant out, that"d be a good time to replace the sending unit.RwP

Do you have actually one of these OBD2 scanners? If therefore which one perform you use. Ns looked on amazon and found several different brands. Car set a code tonight on my way into work so i will prevent in the morning and have that read.
I had actually the codes read and I have P0128 Coolant temp is constantly low. And also P1189 Engine oil push switch fault.For the P0128 I understand to change the thermostat and possibly the sensor. What room the thoughts on the oil pressure switch? must I simply clear the password after I settle the temperature and see if the oil switch code comes back. The vehicle is idling high right now, i assume because it is in open up loop and not warming up.
P0128, placed the t-stat in the first. Ns really doubt the temp sensor needs to be changed unless you have the right to see data from the ECM that is irrational as soon as you have actually a good t-stat in it.P1189 is almost guaranteed the oil press switch itself. This code will not revolve on the MIL. When you revolve the key on, girlfriend most most likely will not see the oil push light come on through the engine off various other than the two second bulb check. If you disconnect the switch, best by the oil filter, and the oil push light come on, put the switch in.

Changed the T-stat and also the sensor today. The vehicle is idling much much better now and the heater is functioning to good. Ns was no going to readjust the sensor till I saw how much the a pains it was to obtain at it and also decided due to the fact that I to be there and also had the sensor come just adjust it. Those the best method to bleed the air the end of the cooling system?I will have actually to examine the oil pressure switch next.
