What causes P0730 code?
What the P0730 code means. P0730 is the OBD-II generic code for an incorrect gear ratio detected in an automatic transmission. The ratio of a combination of engine speed and throttle position and the speed of the transmission is used to determine what gear the transmission will use when driving.
What is a shifting solenoid?
A transmission shift solenoid is what controls the flow of transmission fluid. This is done through a module that sends an electrical signal telling the shift solenoid exactly when to transfer fluid in and out of the transmission along with the right rate.
What does a transmission control module do?
What is a Transmission Control Module? The transmission control module is an electronic component of your transmission that’s in charge of interpreting electrical signals from sensors in other parts of the vehicle.
How do I fix code P0722?
What repairs can fix the P0722 code?
- Repairing or replacing a damaged or faulty transmission output speed sensor.
- Repairing or replacing a damaged or faulty engine coolant temperature sensor.
- Repairing or replacing a damaged or faulty shift solenoid.
- Flushing the system and changing the transmission fluid.
Can you check transmission fluid?
Pull out the dipstick, wipe it clean, replace it slowly, and then pull it back out. Check the fluid level—how high the fluid comes up on the dipstick—against the “full” and “low” or “fill” marks on the dipstick. The color of transmission fluid can tell you a lot about the health of your car’s transmission.
What does code po700 mean?
The P0700 code indicates that there’s a malfunction with your vehicle’s Transmission Control Module (TCM). This computer monitors your transmission and works with the Powertrain Control Module (PCM) and Engine Control Module (ECM) to shift gears when necessary.
