What happens if you have an incorrect gear ratio?
Engine speed is often calculated against the transmission speed sensor to determine gear ratio and torque converter slip. If the calculation does not match the desired value, the Diagnostic Trouble Code is set and the Check Engine Lamp is illuminated. Incorrect ratio codes typically require an advanced mechanical ability and diagnostic tools.
What is the OBD code for incorrect gear ratio?
P0730 is the OBD-II generic code for an incorrect gear ratio detected in an automatic transmission.
What does incorrect gear ratio code p0730 mean?
Mercedes Benz (ML 450) P0730 Incorrect Gear Ratio code P0730 Code…. This code refers to Incorrect Gear Ratio. Besides changing the Transmission Fluid, if it’s the Transmission Sensor, what is the cost for that type of repair?
What causes the Check Engine light to illuminate?
Eventually, the P0730 code will cause the Check Engine Light to illuminate on the dashboard. Along with this indicator, there may also be slipping within the transmission and poor overall transmission performance. The transmission may stay in a low gear for too long, or stay in a high gear until the engine stalls. Fuel economy may worsen as well.
What are the symptoms of the incorrect gear ratio code?
The incorrect gear ratio code may have several causes: What are the symptoms of the P0730 code? Eventually, the P0730 code will cause the Check Engine Light to illuminate on the dashboard. Along with this indicator, there may also be slipping within the transmission and poor overall transmission performance.
When to use the p0730 gear ratio code?
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. If there is a problem with any gear within the transmission, then the P0730 code will appear once this ratio is calculated from the sensor data in the transmission.
Eventually, the P0730 code will cause the Check Engine Light to illuminate on the dashboard. Along with this indicator, there may also be slipping within the transmission and poor overall transmission performance. The transmission may stay in a low gear for too long, or stay in a high gear until the engine stalls. Fuel economy may worsen as well.
Why are there more than 4 gear ratios?
Newer vehicle models are equipped with more than four gear ratios for fuel efficiency. The PCM decides when to shift up or down between gears, based on the vehicle speed vs. throttle position.
