P1870: Understanding The Mysterious Transmission Slippage Fault Code
The P1870 fault code indicates a problem with the transmission component slipping. This occurs when the engine speed is over 500 rpm for 5 seconds, the fuel shutoff is inactive, the throttle angle is between 8.5-35%, the transaxle is not in first gear, the transaxle gear range is D4, the transmission fluid temperature (TFT) sensor input is between 68-266°F, the engine torque is between 50-200 ft-lbs, the engine vacuum is between 0-105 kPa, and the torque converter clutch (TCC) is commanded on and at max apply for over 5 seconds.
The Powertrain Control Module (PCM) detects a TCC slip speed of over 200 rpm for over 5 seconds, and this condition must be met for 3 times with the TCC commanded off each time in between cycles. This fault code indicates that there is a slipping issue within the transmission component, which may require further inspection and repair to ensure proper functioning of the vehicle.
