Does anyone know what this yellow light is for?

 

That means you have a transmission fault.
Sorry for the bad news.

 

ballooning,

It doesn't look as if your engine is running? Rev counter on zero and battery charge light on?

Does the transmission light go off when the engine is running?

That light can come on if something else causes the engine to shut off...Now if you had an OBD2 reader....that would help diagnose your situation.

Best $15 you'll ever spend for this car.

 

A little background: The car stalled one time after about an hour of driving. It started right up and I drove home, about five minutes. Then I drove it another hour, no issues (back and forth to work) I drove it to work this am and it ran fine. On my way home it started to sputter here and there and then stalled several times. Thats when the transmission light came on and the check engine light would blink but not stay on. I left the car idling and it stalled again in the driveway (I made it home thank god.) I connected my code reader to the ODB2 port and it is pulling no codes. Now the car will start but the transmission light stays lite.

Any thoughts?
Also, seems to do it in hotter weather ... the mornings are cool and no issue. The late afternoon its in the 80's and it does it. Always after driving at least 20 miles or so

 

Unless you have a Deluxe Code reader, it doesn't read transmission codes.
If you don't have a hard code the light should go out when running.
Since it doesn't, you need to clear the codes with a delux reader.
Then if it comes back you have a fault.

 

Yeah. Transmission codes are not read by normal code readers. However, check engine lights should set off a code and store that code.

Perhaps the cheaper code readers won’t pull those stored codes, but I could swear my cheap u480 code reader can show active and stored P codes.

I had a similar issue with this car once. It actually stalled out on me while driving before it finally awarded me with the code telling me the EGR was bad. Until then, had some random stalls at stop lights, and some bad idling, where it would dip very low....again at stop lights.

Stalling the engine out could very well light up this transmission light.

 

Well I have finally been able to re-create the stalls. Its when the car warms up. The transmission light is still on, no check engine lights either. I let the car idle in the driveway with the AC on. As soon as the engine warmed up hot, the car stalled. It will start right back up again for a small time then stall again. If I let it cool, it runs fine until hot again.

Also I have C Reader VI + by launch for my ODBII reader. Has always worked well in the past.
Any thoughts?

thanks all

 

So here's what you got.

There is a sensor that is failing you which isn't used for engine warm up during open loop operation. As soon as the car warms up and starts taking readings from sensors, something is telling the engine to shut down.

I'm not familiar with C Reader VI+, but any of them should read the P code. C Reader will NOT read the transmission code.

 

The transmission ecu often acts a "safeguard" for the AJ16 XJS when there is another problem. I recently had a n alternator fail and with the car jumpstarted and the battery only having 11v, I limped along with the transmission light on and the car only holding the lower gears.

As suggested, I would guess that there's hopefully nothing wrong with your transmission but obviously something is causing the stalling.

Yes, it COULD be the transmission, but unless you've done a lot of mileage and the auto fluid and filter haven't been changed for 60k miles, then I wouldn't start there.

See if you can scan the car with any cheap reader OBD plugin and a suitable phone app (mine cost £5 for both) and see if you can pull any fault codes.

Good luck

Hmm any thoughts on what sensor would shut down the car when it gets hot? The CAM and Crank sensors wouldn't do that and there is no trouble with the car starting. Would an engine coolant sensor shut the car down if it fails? O2 sensors would not ... Air or Fuel delivery sensor perhaps ... it does seem like the car is getting no fuel when it stalls ... but its hard to tell. When it first started it would sputter and keep running then eventually stall ...


Hmmm baffled

 

I know this is going to sound crazy. My car would stall out when I took my foot off the gas. I had to use gas and brake at the same time when I came to a stop. During this time, the transmission light would come on. I tightened my throttle cable to increase the idle until I could figure out the problem. The problem turned out to be the EGR valve. All problems were corrected with a new EGR valve. I guess you can remove and clean your existing EGR valve to see if that helps. I should add that it ran fine until it warmed up.

 

Thanks, that is definitely a step I will take!
