#1: Engine Temperature Gauge Stays Very Low Author: SolidRegardless, Posted: Tue Oct 16, 2012 8:22 am ---- I recently bought yet another Peugeot 206 1.4 LX (2001) as a home project to learn how to repair and service cars (novice home mechanic) and have noticed the following.
The engine temp gauge never goes above 1/5th. In otherwords, it always stays cool. This is even after a good run and then letting the engine idle for 20 minutes immediately after.
I can understand the gauge staying quite cool when at speed, but even then it seems a little too low. It does move, but as I said, not very far.
What I am concerned with is that the coolant is not being injected at the correct time and that the engine might get damaged if it begins to get too hot.
1. Are there failsafe sensors to detect this type of problem?
2. If there are fail points that could cause this, what tests can I perform to identify possible issues.
3. AOI - any other ideas..
There are no faults being reported from my OBD reader.
Thanks!
SR

#3: Re: Engine Temperature Gauge Stays Very Low Author: SolidRegardless, Posted: Tue Oct 16, 2012 9:59 am ---- Hmm, ok. I am not sure about that, but I will check tonight when I get home. Worth a look. Might be that it needs replacing. They are pretty cheap so I might replace it if I can't find anything else wrong.
Thanks,

2001 1.4i will be non-mux and has seperate sensor and circuit for the gauge.
It's very inaccurate -/+ 10 C and the gauge motor itself could be up the creek too.
It usually is thermostat though so check that first.

Allow to warm on idle regularly checking top hose temp by hand.
If it warms gradually the stat is stuck open or not fitted.
If it gets hot suddenly the stat exists and is opening at a set temp.
However, stats get weak with age and often open early.
They are cheap - just change it (especially now winter is approaching) and get 2-3 more mpg.

#8: Re: Engine Temperature Gauge Stays Very Low Author: MrBSI, Location: What's it to you? ? ?Posted: Tue Oct 16, 2012 2:22 pm ---- You can use a multimeter IF it has temp function on it OR use a infra red thermometer if you have either of these in your tool box.

The Peugeot Planet / Citroen Lexia software isnt actually a problem as you can download it FREE if you know where to look, its the correct Planet / Lexia diagnostic leads that cost the money & you cant install the software without the lead.

I've never seen an interface come without the software.

I've got the software, just no interface YET

#15: Re: Engine Temperature Gauge Stays Very Low Author: SolidRegardless, Posted: Tue Oct 23, 2012 2:20 am ---- My new thermostat should be arriving today, but I have just noticed something else odd happen. The gauge stays very low like I said, but today on the way to work, the temperature gauge suddenly flew into the red out of nowhere and I read off code P0115 from the OBD.
I didn't think the two components were linked with regards to their individual circuit. Functionally, sure. Could this now mean that the coolant sensor is faulty also? Seems a bit of a coincidence.
My cooling fan doesn't come on, but I have assumed that is because of the thermostat probably being stuck open.
Could the thermostat have suddenly stuck closed? I didn't notice the fan coming on either so I am not sure about this.
I am also starting to suspect the earth, as I am sure there could be some corrosion in this old baby.
So, to summarise, here are my problems:
1. Gauge stays very low (except suddenly this morning as I was pulling into work)
2. Fan never comes on
3. After about 35 miles the performance is a little erratic
4. Today, the gauge flew into the red and car logged a P0115
(the engine didn't seem abnormally hot)
Any ideas as to where I should focus?
I am planning on seeing how the car is after I have replaced the thermostat but if I should check things asap then suggestions would be cool (excuse the pun).
