A couple of days ago the check engine light went on in my 2014 Spark EV2 LT. I scanned the code and only found one default - P0713 Powertrain, trans fluid temp sensor circuit high input. I cleared the code and today, two days later, it came on again. I am not sure if the code description is correct or if the Spark EV uses the code for a similar fault. Right now, the outside temperature is hot - 90 - 100 deg. F.
Has anyone else experienced this code? If so, what was the fix?
What the P0713 code means
P0713 is an OBD-II generic code for a voltage problem with the automatic transmission temperature sensor. If this code is triggered, the TCM is reading voltage that is too high for the manufacturer’s parameters, meaning the automatic transmission fluid is too hot.
What causes the P0713 code?
There can be a variety of causes for a P0713 – some more severe than others – but it’s important to treat this code seriously as it could lead to costly repairs if ignored. Some of the most likely causes are:
Low automatic transmission fluid from a leak
Dirty automatic transmission fluid
Faulty automatic transmission temperature sensor
Slipping or damaged transmission
Damaged sensor wiring
Faulty TCM and or engine control module
That's just info from you mechanic...my question is...after clearing the code how far/long did you drive before it set again? Also on torque pro you have the trans temp pid...see what it reads cold and watch as you drive, from cold it should be reading about ambient air temp. This is an important one not to ignore as trans temp is also an indication of motor temp on our electric sparks (trans fluid also cools the exterior of the motor). If your temp readings are normal (ambient cold) and move up as you drive likely the sensor is not the issue. Next thing would be the fluid condition/level, if not a sensor issue or fluid issue troubleshooting will get a bit more tricky. I would definitely check those 2 things first before moving to anything else.
Is hot here in sacramento as well and have not seen over 130F on trans temps since monitoring the pids for the last few days, but also haven't been driving more than 20-25 minutes at a time.
