What does the OBD code p0868 stand for?
OBD-II Code P0868 is defined as a Transmission Fluid Pressure Low The Transmission Fluid Pressure Sensor tells the Transmission Control Module (TCM) the pressure of the fluid going through the transmission. When the TCM detects an incorrect signal from the Transmission Pressure Sensor,…
What does the transmission fluid pressure code p0869 mean?
In the context of code P0869, “transmission fluid pressure” refers to transmission line pressure, which is the pressure that holds various components in place when a particular gear is selected.
When to set DTC Transmission Control Module p0867?
The Transmission Control Module (TCM) continuously monitors actual line pressure and compares it to the desired line pressure. If the difference between actual line pressure and desired line pressure is 10 psi (.7 kg/cm2 ) or greater, DTC P0867 will set.
How does the solenoid work on a p0868?
Transmission system will default to open loop line pressure control resulting in a fixed solenoid duty cycle. This duty cycle will change slightly depending on temperature and current gear. Need more information on how to fix the P0868 code?
What should line pressure be in DTC p0867?
If the difference between actual line pressure and desired line pressure is 10 psi (.7 kg/cm2 ) or greater, DTC P0867 will set. Transmission system will default to open loop line pressure control resulting in a fixed solenoid duty cycle.
What causes the p0868 trouble code on a transmission?
Transmission fluid serves to lubricate the transmission, and for vehicles with automatic transmissions, to cool the transmission system as well. When the powertrain control module (PCM) detects that the pressure of the transmission fluid is either too high or too low, the P0868 trouble code will be triggered. What causes the P0868 code?
What does the p0868 dodge pressure sensor mean?
P0868 DODGE Meaning Line pressure is measured by the Line Pressure Sensor (LPS) and regulation is achieved by changing the duty cycle of the Pressure Control Solenoid (PCS) controlled by the Transmission Control System. (5% duty cycle = solenoid off = Max line pressure, 62% duty cycle = solenoid on = Min line pressure).
When does the PCM set the code p0868?
The PCM interprets the received signal voltage as pressure, and will set code P0868 and illuminate a warning light when it senses that the transmission fluid pressure has fallen below a specified value. Note that in some cases, the PCM may also initiate a fail-safe or limp mode in order to protect the transmission.
