The P1887 fault code refers to an issue with the Torque Converter Clutch Release Switch Circuit. This code is triggered when the Powertrain Control Module (PCM) detects that the Torque Converter Clutch (TCC) Release pressure was present, indicating that the switch is open. To understand this fault code, let’s break it down.

When the engine speed is over 500 rpm, the TR switch is in D4, and the TCC is commanded on, the PCM monitors the TCC slip speed.

If the slip speed falls within the range of -20 to +40, the PCM expects the TCC Release pressure to be present, indicating that the switch is closed. However, if the PCM detects that the TCC Release pressure is not present, it triggers the P1887 fault code. This fault code indicates a potential issue with the Torque Converter Clutch Release Switch Circuit. It is important to address this issue promptly to ensure proper functioning of the TCC and prevent any further damage to the transmission system.

How can I determine if the Torque Converter Clutch (TCC) Release Switch is faulty when I see the Engine Light ON?

If you see the Engine Light ON, it could be due to a faulty Torque Converter Clutch (TCC) Release Switch. To determine if this is the issue, check for symptoms like the Engine Light or Service Engine Soon Warning Light being illuminated. The cause could be a faulty TCC Release Switch, an open or shorted TCC Release Switch harness, or a poor electrical connection in the TCC Release Switch circuit. To fix the problem, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Also, look for broken, bent, pushed out, or corroded pins in the connectors.
