What does P1399 code mean?
random misfire occurring
OBD code P1399 On Honda vehicles the OBD code p1399 indicates that there is a random misfire occurring in the engine.
What does it mean when your shift code is p0780?
In my own personal experience, when a code P0780 is stored, it means that the powertrain control module (PCM) has detected a problem with automatic transmission shifting. This code may be caused by either a mechanical or an electronic malfunction but is limited to vehicles with automatic transmissions.
When is a p0780 code detected on a Honda transmission?
The P0780 codes is detected when no rotation change occurs between input (turbine revolution sensor) and output (revolution sensor) and shifting time is long or when shifting ends immediately or when engine revs up unusually during shifting. The Transmission Control Module (TCM) monitors the transmission mechanical shifting through various sensors.
When does DTC p0780 gear selection malfunction?
DTC P0780: The TCM (Transmission Control Module) or PCM (powertrain control module) monitors the transmission mechanical shifting through various sensors. This malfunction is detected when the transmission does not shift as instructed by the TCM.
What causes an OBD code for transmission malfunction?
Since this code may be caused by either an electronic or mechanical malfunction, you will also want to inspect the transmission, transmission cooler, and transmission cooling lines for signs of leakage. If the transmission is low on fluid, it will cause the transmission to slip, fail to shift properly, and experience delayed engagement.
What does p0770 code mean?
In this case, the P0770 OBD-II trouble code is associated with a general malfunction with the the transmission Shift Solenoid “E” Circuit. Example of shift solenoids: What is the severity of this DTC? The severity of this code normally starts as moderate, but it can progress to a more severe level rapidly when not corrected in a timely manner.
What does the OBD code p0783?
What does the code mean? OBD-ii Code P0783 definition: This P0783 code indicates that the 3-4 shift valve in the valve body is locked in the direction of the spring compression. The Transmission Control Module (TCM) controls the gearshifts by turning the shift solenoid valves “ON/OFF” and switching oil pressure to the valves in the valve body.
What is code p0785?
P0785 is a diagnostic trouble code (DTC) for “Shift/Timing Solenoid Malfunction/ 3-2 Shift Solenoid Circuit Electrical”.
