I have a 2001 aurora and code p1860 p1860 came up what is this and how much to fix


P1860 All GM - TCC (transmission Torque Converter Clutch) PWM Solenoid Circuit Electrical.
P1860 Description The Torque Converter Clutch Pulse Width Modulation (TCC PWM) solenoid valve controls the fluid acting on the converter clutch valve. The converter clutch valve controls the TCC application and release. The solenoid attaches to the control valve body within the transmission. The solenoid receives ignition voltage through circuit 239. The Powertrain Control Module (PCM) controls the solenoid by providing a ground path on circuit 418. Current flows through the solenoid coil according to the duty cycle (percentage of ON and OFF time). The TCC PWM solenoid valve provides a smooth engagement of the torque converter clutch by operating during a duty cycle percent of ON time.
When is the code detected? When the PCM detects a continuous open, short to ground or short to power in the TCC PWM solenoid valve circuit, then DTC P1860 sets. DTC P1860 is a type B DTC.

Possible causes - Faulty Torque Converter Clutch Pulse Width Modulation (TCC PWM) Solenoid
- Torque Converter Clutch Pulse Width Modulation (TCC PWM) Solenoid harness is open or shorted
- Torque Converter Clutch Pulse Width Modulation (TCC PWM) Solenoid circuit poor electrical connection. Unless you have a factory manual and very good auto repair skills this is best left to an expert. It is a messy dirty job that requires removing the parts inside the transmission for testing..

Code p1860 comes up when I scanned a 2000 Isuzu rodeo. can you help?


That code indicates a TCC PWM Solenoid Circuit Failure (torque converter clutch pulse width modulation (TCC PWM) solenoid valve controls the fluid acting on the converter clutch valve):
http://www.troublecodes.net/isuzu/iszuobd2.shtml
is where I found that information.
I hope that will help.

I have a 2001 caddy deville that i am buying there is a code that comes up P1860 can you tell me what that is Thank you Paul


Circuit Description with 4T80-E Automatic Transaxle
Ignition voltage is provided to the torque converter clutch pulse width modulated (TCC PWM) solenoid valve. The PCM controls the ON and OFF time of the solenoid by providing a ground through the output driver module (ODM) . The PCM uses a PWM duty cycle, in order to control application and release of the TCC. When the solenoid is commanded OFF, the PCM senses high volts. When the solenoid is commanded ON, the PCM senses low volts. If the PCM detects a continuous open, short to ground or short to voltage in the TCC PWM solenoid valve circuit, then DTC P1860 sets. DTC P1860 is a type B DTC.

Conditions for Running the DTC
  • The system voltage is 8-18 volts
  • The engine run time is greater than 5 seconds.
  • The TCC PWM solenoid valve duty cycle is 10% or less or 90% or greater.
Conditions for Setting the DTC
The TCC PWM solenoid valve feedback circuit indicates a continuous open, short to ground or short to voltage for 4.3 seconds.

CODE P0741


P0741 "Torque Converter Clutch Solenoid stuck off"
If the PCM detects high torque converter slip when the TCC is commanded ON, then DTC P0741 sets. The Powertrain Control Module (PCM) controls the Torque Converter Clutch Solenoid Valve (TCC Sol. Valve) Pulse Width Modulation (PWM). The solenoid controls the hydraulic fluid for TCC apply and release. When the TCC is applied, the engine is coupled directly to the transmission through the TCC. The TCC slip speed should be near 0.
Thank you for using Fixya and good luck

Hi , malfuction light came on today on dash but


You need to get a diagnostics check, ask mechanic for list of codes you can then check the problem out on http://www.bluejag.co.uk to find the actual problem. Any decent mechanic shoud be able to read the code you don't have to go to Jag
