We recommend Torque Pro. In transmissions with electronic shift controls, power is supplied to the transmission control module through the transmission control output circuit. If the vehicle experiences a problem that requires the transmission to be put into limp mode, the transmission control output circuit voltage changes. The transmission will engage in low gear as a self-protective measure and will not shift.

When the engine is mopar 360 engine for sale or the key is turned to the run position, the transmission control module performs a system check.

It looks for voltage on the transmission control circuit.

Dodge Cummins Diagnostic Trouble Codes

If the circuit is open, it requests the transmission control circuit to be powered up from the PCM. In most vehicles, if the DTC is active the transmission will engage limp mode and will not shift.

Because DTC P is primarily related to an electronic shift control issue, low battery voltage can cause the code to set. Before beginning any in-depth electronic diagnosis, check that the battery voltage is proper. A telltale sign that the battery is weak and may be causing DTC P is if you require a boost to start the engine. Alternatively, perform a load test on the battery. Many auto parts retailers will perform out-of-vehicle load testing on batteries for no charge.

If the load test fails, replace your battery. Clear the DTC with a code reader. If the code returns, continue with diagnosis. Locate the transmission control circuit for your vehicle at the PCM connector.

You will need a wiring diagram specific to your make and model for accurate diagnosis, which you may be able to get printed from a parts retailer. The transmission control circuit should read 5. If the resistance is less than 5. Trace the circuit while monitoring the resistance, wiggling the wire and checking for breaks or rubbed sections in the wire. If you detect a change in resistance while wiggling a section, perform a repair on the wire, clear the codes and retest. Using a DVOMcheck the transmission control circuit resistance in the same way as checking for a short to ground.

If the resistance is more than 5. To check for an open circuit, trace along the length of the transmission control circuit, checking for breaks in the wiring. Repair any broken wiring and make sure all connectors are fully seated and locked.

Pay close attention to connectors, looking for corrosion, bent or broken pins, or moisture in the connector. Repair any connector issues even if they are not specifically part of the transmission control circuit as they may serve a function in providing power to the transmission control circuit. Test the PCM by replacing it with a known good module and retest. Code P can set due to low battery voltage caused by either improper charging system operation or excessive draw during starting.

With the engine running, test the alternator output with your DVOM. When running, your alternator should produce in the vicinity of Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins. Tech Notes What does this mean? The auto repair labor rates vary widely across the country, and even within the same city. When is the code detected?

If the actual line pressure is consistently lower than the target while driving, the line pressure low DTC P will set. The Transmission Control System calculates the desired line pressure based on inputs from both the engine and transmission. The Transmission Control System calculates torque input to the transmission and uses it as the primary input to the desired line pressure calculation. This is called Torque Based Line Pressure.

In addition, the line pressure is set to a preset level or kPa or psi during shifts and in Park and Neutral to ensure consistent shift quality. The actual line pressure is continuously being compared to the desired target line pressure. Get Access to Factory Service Manuals. Need more help?

Since the mid s, every vehicle with an automatic transmission has been designed with electronic shift controls. These computer controlled transmissions supply power to the transmission control module through a transmission control output circuit. A P code means that low voltage is detected from the transmission control module circuit.

Low voltage from the battery, or an open or shorted circuit in the transmission control circuit are common causes of a P code. In some vehicles, the transmission may shift as designed and display no symptoms other than an illuminated MIL and stored code. Since the P code is related to electronic shift control problems, a low voltage condition from the battery can be at fault. A technician should check to ensure that battery voltage is proper before going any farther with in-depth electronic diagnosis.

Telltale signs of a weak battery include slow or weak cranking and a frequent need for jump-starts to start the engine. Load test the battery — many auto parts stores will perform load testing on batteries out of vehicle for no charge.

With the engine running, use your multimeter to check alternator output. A normal alternator should produce around A starter that has an excessive voltage draw while cranking can cause erroneous codes in the PCM. Slow engine cranking or no-crank situations while the battery is fully charged can both be indicators.

Clear the DTC with a code reader and test drive the vehicle. If the code returns, move on with diagnosis. This transmission control circuit should read 5.

Any resistance reading of less than 5. Locate the ground wire for the circuit and monitor the resistance while you wiggle the wire and check for any breaks or chafed sections.Check the "Possible Causes" listed above.

Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. P DODGE Description The transmission control relay is used to supply power to the solenoid pack when the transmission is in normal operating mode. When the relay is off, no power is supplied to the solenoid pack and the transmission is in Limp-in mode.

It is referred to as the Transmission Control Relay Output circuit or switched battery. After a controller reset ignition key turned to the run position or after cranking enginethe controller energizes the relay. Prior to this the PCM verifies that the contacts are open by checking for no voltage at the switched battery terminals. After the relay is energized, the PCM monitors the terminals to verify that the voltage is greater than 3 volts.

P0882 OBD-II Trouble Code: TCM Power Input Signal Low

Diagnosing this code accurately beyond the basic steps outlined here almost always requires advanced diagnostic equipment such as transmission simulators and sometimes oscilloscopesabove average diagnostic skills in general, and expert-level knowledge of automatic transmissions and their control systems, in particular.

Non-professional mechanics are strongly urged NOT to continue the diagnostic steps beyond what is presented here; doing so could cause irreparable damage to the transmission as well as the entire electrical system of the application. However, this pressure is not constant across all gears; the desired pressure for a particular gear is calculated by the Transmission Control System, using measured engine torque as the primary input data, which is supported by input data from various engine and transmission sensors.

Pressure variation and regulation is accomplished by varying the duty cycle of the Pressure Control Solenoid. In practice, the transmission line pressure is set to a predefined range. In a fully functional transmission, the actual pressure is both continuously monitored by a dedicated line pressure sensor, and compared to the desired pressure.

How to fix your Transmission Control Module TCM, you have to find it first. NAG

NOTE: Take note that if the transmission had become noisy at about the same time code P appeared the transmission had already suffered severe mechanical damage, and trying to resolve this code at this point is a waste of time and money. If the transmission is noisy the only viable option is to replace the transmission. Record all fault codes present, as well as all available freeze frame data. This information can be of use should an intermittent fault be diagnosed later on.

Refer to the manual to locate the pressure control harness, but be sure to determine the color coding and function of each wire in the harness to avoid testing the wrong circuit.

Perform a thorough visual inspection of all associated wiring and connectors, and look for damaged, burnt, shorted, disconnected, or corroded wiring and connectors.

Make repairs as required if damage is found. Compare all obtained readings with the values stated in the manual, and repair or replace wiring as required to ensure that all electrical values fall within the ranges specified by the manufacturer.

NOTE 1: Pay particular attention to the internal resistance of both the pressure control solenoid, and the line pressure sensor since resistance is a reasonably good indicator of their overall condition. Take note that if the fault persists beyond Step 3, the better option is to refer the vehicle to the dealer or other competent repair facility for professional diagnosis and repair.
