A P0734 trouble code indicates that an abnormality has been detected in the gear ration of one of the automatic transmissions gears, causing the storage of a code in the Powertrain Control Module (PCM) and illumination of the Check Engine Light.
How do I fix error code P0734?
What Repairs Will Fix P0734?
- Change transmission fluid / filter.
- Repair or replace damaged wiring and/or connectors.
- Repair or replace failed transmission or torque convertor component.
What does P0734 mean?
Code P0734 When the code P0734 is set in the Powertrain Computer, it means that the Powertrain Computer or PCM is seeing a greater than a specified RPM difference between the rotational speed of the Input RPM Sensor and the Transmission Output RPM Sensor when the vehicle is in 4th gear.
How do I fix code P0733?
Repairs that can fix a P0733 code would include:
- Replacing a shift solenoid.
- Replacing the powertrain control module.
- Replacing the transmission module (if applicable)
- Adding or replacing the transmission fluid and filter.
- Overhauling the current transmission.
- Installing a brand new transmission.
What is code P0733?
OBD-II Code P0733 is defined as a Gear 3 Incorrect Ratio. The purpose of the automatic transmission is to match the engine’s optimum power and torque characteristics to the driver’s desired rate of acceleration and speed by auto-selecting different gear ratios or ‘speeds’ to power the wheels.
What is P0744 engine code?
When the ECU stores a P0744 diagnostic trouble code, it means the ECU isn’t able to be in full control of the torque convertor clutch.
What causes incorrect gear ratio?
The incorrect gear ratio code may have several causes: Bad or dirty fluid in the transmission. Low fluid in the transmission. Broken mechanical components within transmission.
Why you should check your transmission fluid?
If your fluid is low, it doesn’t necessarily mean you’re headed for disaster, but it does most likely mean there is a leak somewhere in the system. Filling up the transmission and then checking it daily to see how quickly the level goes down can be a good way to assess the severity of a potential leak.
Can you check transmission fluid?
Locate automatic transmission fluid dipstick, typically near where the transmission or transaxle meets rear of the engine. It looks similar to the oil dipstick. Remove automatic transmission fluid dipstick. Wipe clean, reinsert fully and remove again.
How do I fix code P0174?
What repairs can fix the P0174 code?
- Replacing mass air flow sensor.
- Cleaning mass air flow Sensor.
- Replacing faulty oxygen sensor.
- Replacing PCV valve.
- Replacing vacuum line.
- Replacing EGR valve.
- Replacing brake booster.
- Replacing valve cover gasket.
Can you drive with incorrect gear ratio?
Problems with the incorrect gear selection may cause drive-ability symptoms. The check engine light or malfunction indicator lamp will be illuminated as long as a P0730 is recorded in the ECC.
Where are the shift solenoids located?
The shift solenoid is located inside the oil valve connected to the valve body. The shift solenoid controls gear engagement and gear shift. The engine control module or the transmission control module in the vehicle’s engine controls the shift solenoid electronically.
