What is P0735 : Engine Error code Causes Explained
This guide covers the P0735 engine error code, which indicates an erroneous fifth gear ratio. It can cause transmission sliding, poor acceleration, and lower fuel economy, which could affect drivability.
How to Identify a DTCs Number
The P0735 engine error code refers to “Gear 5 Incorrect Ratio. The Powertrain Control Module (PCM) triggers this code when the 5th gear ratio does not match engine speed and vehicle speed sensor data.
Understand, this trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
To identify P0735, use an OBD-II scanner to retrieve stored codes and check for any additional transmission-related errors.
Causes of P0735 Code:
- Transmission failure:
The transmission may have failed internally. - Faulty transmission control module (TCM):
The TCM may have detected that the transmission is not shifting into fifth gear - Powertrain Control Module (PCM) failure:
The PCM may have detected an abnormal gear shift ratio. - Transmission fluid:
The fluid may be low, dirty, or contaminated. - Shift solenoid failure:
The shift solenoid may be faulty. - Wiring issues:
There may be a wiring issue - Clogged fluid filter:
The fluid filter may be clogged or worn out. - Worn out pump:
The transmission pump may be worn out. - Internal blockage:
There may be an internal blockage in the transmission
Risk Level of P0735 Error Code:
A High Risk Level means severe transmission issues, which can cause slipping, rough shifting, or even transmission failure.
It is strongly advised to get the car diagnosed and repaired if the P0735 code continues in order to prevent dangerous driving situations.
Common Car Brands Affected by P0735 Code:
The P0735 engine error code is commonly found in the following list.
- Ford
- GM
- Toyota
- Jeep
- Chrysler
- Dodge
- Honda
- Nissan
