Coolant Temp Sensor Question

[phoonTy]

namely, how long should they last? I bought my truck in march of '02 and had to replace it in Aug. of '02. Today, after getting the ps pump back on and bled, I decided to go for a test drive. Almost immediately, the check engine light comes on.

I immediately thought idle, because my truck has always had problems with that. drove around, did my errands, then got back to the apt to run the codes, and I get code 15. Low Coolant Temp.

Could that be because the truck sat for 2, almost 3 weeks in cold weather? or is my coolant in need of checking/replacing? Or do these things just not last very long?

It's no big deal to replace, $7 - $13 if I remember correctly, I was just wondering if my truck has a gremlin that makes them go bad prematurely.

Not aware of a sensor-failure-gremlin, but have seen the wiring to the sensor go bad on several trucks.

i'll have to trace it tomorrow and see if i've got any nicks in the wires, etc. is there any specific way i should replace the wires if they are bad? or just splice in some new wire?

thanks for the input.

pretty sure that has to do with the lower cche sender. The one in the intake goes to the ecm, whereas the one in the driver side head is for the gauge.

i'll have some of it apart this coming weekend. have some "wobble" in my crank pulley. I think it's just not seated correctly on the balancer, so while I'm at it, I'll check the senders and wires. thanks for the input.
