What is CID 1017:
cid 1017 refers to a fault in the vehicle’s transmission system, specifically related to the transmission fluid temperature sensor. when this sensor malfunctions, it can lead to poor shifting, overheating, or transmission failure.
Why This Happens:
- faulty transmission fluid temperature sensor.
 - shorted or damaged wiring in the sensor circuit.
 - low transmission fluid levels.
 - blocked or malfunctioning solenoids.
 - ecm failure to process data correctly.
 
How to Fix It:
- inspect the transmission fluid temperature sensor for failure.
 - test sensor voltage and resistance.
 - check transmission fluid levels and top up if needed.
 - replace the sensor or damaged wiring if necessary.
 - reset ecm and verify correct fluid temperature readings.
 
How to Avoid It Before It Happens:
- regularly inspect transmission fluid levels and condition.
 - monitor transmission temperature through diagnostics.
 - clean sensors and connections periodically.
 - clue’s fleet management software helps track transmission fluid health to prevent overheating and enhance vehicle performance.
