P011D Code:

OBD-II Diagnostic Powertrain (P) Trouble Code

Possible Cause

Common causes of P011D include a faulty electronic pressure control solenoid, hydraulic blockages inside the internal transmission fluid passages, mechanical internal transmission failures, low transmission fluid, dirty or contaminated transmission fluid, a faulty PCM or transmission control module.

Common Symptoms

  1. The sensor is supplied with a low voltage (usually 5-volts) power wire and a ground wire
  2. Repair or replace any open, shorted, damaged, or corroded items as required and retest the system to make sure that repairs were successful
  3. Pay particular attention to wiring and connectors that have been contaminated due to engine oil or transmission fluid leaks, burned on hot exhaust pipes, or damaged due to road debris. Inconsistencies between the input and output speed sensor readings may be interpreted by the PCM as a transmission friction element application malfunction
  4. If either the reference voltage or ground circuits are open, use the digital volt/ohmmeter to check for continuity (disconnect all related control modules from the circuit before checking circuit resistance or controller damage may occur) and resistance in all circuits

P011D Troubleshooting

A sure sign of this is smoke or steam being emitted from underneath the hood. The ignition timing could be set incorrectly and will require adjustment. If, when looking under the hood, you notice that the drive belts appear loose, they need to be tightened or completely replaced. If there is a noticeable pool of fluid underneath the car, this could be a sign of the cylinder head gasket failing. That will be confirmed in the form of billowing smoke being blown from the exhaust system. P011D OBD2 may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.

How to turn off P011D check engine light ?

There are two ways to turn off the check engine light:

A repair technician can do so once repairs have been made.
The OBD II can automatically turn it off when it fails to detect the problem after several diagnostic cycles.
