Re: 2001 SL1 High Idle Problem

I had the scanner plugged in all drive home and monitored the TPS closely the whole way. I noticed the TPS (%) started at 0.3 when sitting at idle in the parking space when I first got in... As I was...

Re: 2001 SL1 High Idle Problem

Okay, on my way home from work, which is 45 miles of highway driving, I'll have the scanner on and reading the live data. I'll let you know what it indicates tonight, both when it's acting normally...

Re: 2001 SL1 High Idle Problem

Okay that makes sense. I replaced the PCM over the weekend so I am confident it is not that.

I can definitely replace the TSP (again) but it would be number 3 in 2 years. I guess it's possible...

Re: 2001 SL1 High Idle Problem

I have checked the data when the idle was behaving correctly and when it was acting up. The big different I see is the TPS (%) reading around 2.9/3.1 when the idle was "stuck" high and 0.7-1.0 when...

Re: 2001 SL1 High Idle Problem

I think the world of the Saturn is a shrinking one.

I am scraping all corners of the internet in hopes of finding a clue to solve my problem. At this point it's just about closure. I posted to the...

Re: 2001 SL1 High Idle Problem

I'd like to submit a quick follow up. I tried an idea submitted to me from Reddit and swapped out the ECU for another ECU that was compatible. I performed the relearn procedure laid out here:...

Re: 2001 SL1 High Idle Problem

I have not experimented with this, though I thought the throttle was electronic, and no physical/mechanical cable to disconnect... but I will double check tomorrow.

I am also curious about the...

Re: 2001 SL1 High Idle Problem

So are you recommending buying an OEM TPS and switching it in? Does anyone have any explanation of what the U1301 code could mean?

Re: 2001 SL1 High Idle Problem

Thanks for your help. In the times where the car is stuck idling too high, the TPS position seems to be around 2.7, it did it again after I posted earlier.

I disconnected the TPS wires while the...

Re: 2001 SL1 High Idle Problem

Thanks for the reply, I took a reading earlier last week before I replaced the thermostat and the TPS was reading 2.7 at that particular time, so I wonder if there is something going on there. The...

Re: 2001 SL1 High Idle Problem

Hi guys,

I'd like to follow up on this thread with some updates. I know it's been a couple of weeks but it took some time for me to able to change the thermostat.

I replaced the thermostat as...

One last update. When I went to my car after all day at work I checked the temperature information:

Coolant temp: 45 degrees
IAT temp: 39 degrees
Air temperature: 38 degrees
RPMs (while sitting...

Re: 2001 SL1 High Idle Problem

Yeah I was thinking about replacing the thermostat, ignoring the ECTS for now. I am heading back to my car, will plug in the reader and see what temperature info it reads.

Re: 2001 SL1 High Idle Problem

Well I can say we have never changed the thermostat so that is going to be a place to focus on when I have time to look into it. After some research on replacing the sensor, it does not look to be...

Re: 2001 SL1 High Idle Problem

Thanks for the advice. Would this also explain the intermittent high-idle situations where the car seems "stuck" at 1700 RPMs, and must be reset by restarting the engine quickly?

Re: 2001 SL1 High Idle Problem

The gasket was replaced about 18 months ago, and there was some improvement in the symptoms.

Is there a thermostat other than the engine coolant temp sensor? Also, should I think about switching...

Re: 2001 SL1 High Idle Problem

Thanks for the responses.

I paid attention to the RPMs today when I got back to my car after work. It had been sitting in 35-40 temperatures all day so it was cold when it started. When I started...

Re: 2001 SL1 High Idle Problem

Perhaps... We have changed the TPS at least once in the last year, and I know the current TPS was tested by a mechanic and he declared it functional. Is there a chance the TPS connection could be...
