The top 4 most common OBD-II trouble codes for a Toyota Rush include P0717, P0770, P0705, and B2000. These codes can help identify issues with the vehicle’s transmission, airbag system, and engine. By knowing these codes and what they mean, Toyota Rush owners can take the necessary steps to diagnose and fix any engine problems their vehicles may encounter.
Toyota Rush OBD DTC P0717
Description:
This DTC stands for “Transmission Input Shaft Speed Sensor Circuit No Signal.” It means that the Powertrain Control Module (PCM) has not detected a signal from the input shaft speed sensor or the signal is intermittent.
Symptoms:
– Malfunction Indicator Light (MIL) illumination
– Harsh shifting or no shifting at all
– Decreased fuel efficiency
– Engine may stall when coming to a stop
Cause:
– Faulty input shaft speed sensor
– Wiring issues, such as a broken or shorted wire
– Failed PCM
Possible Location:
The input shaft speed sensor is usually located on the transmission housing, but the exact location may vary depending on the vehicle make and model.
How to Fix the Problem:
– Replace the input shaft speed sensor
– Repair or replace any damaged wiring
– Replace the PCM if it is determined to be faulty
How Difficult to Fix:
This depends on the root cause of the problem. If it is a faulty sensor, it can be a relatively easy fix that can be done with basic tools. If it is a wiring issue, it can be more challenging, and may require specialized tools and knowledge.
Can You Drive With This Code:
You can drive with this code, but it is not recommended as it can cause further damage to the transmission.
How to Clear the Code:
Disconnecting the battery will reset the PCM and clear the code, but it will also reset any other learned parameters. It is recommended to use an OBD-II scanner to clear the code.
Tools Needed to Use:
– OBD-II scanner to read and clear the code
– Multimeter to test wiring and sensors
Step-by-Step Diagnostic Procedure:
1. Use an OBD-II scanner to read the code and check for any other related codes.
2. Check the input shaft speed sensor for proper resistance and voltage output using a multimeter.
3. Inspect the wiring and connectors for any damage or corrosion.
4. Check the transmission fluid level and condition.
5. If all else fails, the PCM may need to be replaced.
Toyota Rush OBD DTC P0770
Description:
This DTC stands for “Shift Solenoid E Malfunction.” It means that the Powertrain Control Module (PCM) has detected an electrical problem with the Shift Solenoid E circuit.
Symptoms:
– Check Engine Light (CEL) illumination
– Harsh shifting or no shifting at all
– Decreased fuel efficiency
– Transmission slipping or overheating
– Decreased acceleration
Cause:
– Faulty Shift Solenoid E
– Wiring issues, such as a broken or shorted wire
– Failed PCM or Transmission Control Module (TCM)
Possible Location:
The Shift Solenoid E is typically located inside the transmission, but the exact location may vary depending on the vehicle make and model.
How to Fix the Problem:
– Replace the Shift Solenoid E
– Repair or replace any damaged wiring
– Replace the PCM or TCM if it is determined to be faulty
How Difficult to Fix:
The difficulty of fixing this issue depends on the root cause of the problem. If it is a faulty solenoid, it can be a relatively easy fix that can be done with basic tools. If it is a wiring issue or a faulty PCM/TCM, it can be more challenging and may require specialized tools and knowledge.
Can You Drive With This Code:
You can drive with this code, but it is not recommended as it can cause further damage to the transmission and reduce the vehicle’s performance.
How to Clear the Code:
Disconnecting the battery will reset the PCM and clear the code, but it will also reset any other learned parameters. It is recommended to use an OBD-II scanner to clear the code.
Tools Needed to Use:
– OBD-II scanner to read and clear the code
– Multimeter to test wiring and solenoids
Step-by-Step Diagnostic Procedure:
1. Use an OBD-II scanner to read the code and check for any other related codes.
2. Test the Shift Solenoid E for proper resistance and voltage output using a multimeter.
3. Inspect the wiring and connectors for any damage or corrosion.
4. Check the transmission fluid level and condition.
5. If all else fails, the PCM or TCM may need to be replaced.
Toyota Rush OBD DTC P0705
Description:
The P0705 code indicates that there is an issue with the range switch on the Toyota Rush.
Symptoms:
– Engine warning light may illuminate
– Transmission shifting may become erratic
– The vehicle may not move when shifted into gear
Cause:
This code can be caused by a few different issues, including:
– A failed range switch
– A damaged wiring harness
– An issue with the transmission control module
Possible Location:
The range switch is typically located near the transmission.
How to Fix the Problem:
The exact fix for this code will depend on the cause of the issue. Possible fixes include:
– Replacing the range switch
– Repairing or replacing the damaged wiring harness
– Replacing the transmission control module
How Difficult to Fix:
The difficulty of fixing this code will vary depending on the cause of the issue. Replacing a failed range switch is typically a relatively straightforward process, while repairing or replacing a damaged wiring harness can be more involved.
Can You Drive With This Code:
It is not recommended to drive a vehicle with this code present, as it can cause damage to the transmission and other components.
How to Clear the Code:
Disconnecting the battery can reset the code, but this may not resolve the underlying issue. It is recommended to have the vehicle properly diagnosed and repaired to prevent further damage.
Tools Needed:
– OBD-II scan tool
– Multimeter
– Socket set
The OBD-II scan tool is needed to retrieve the code and diagnose the issue. The multimeter can be used to test electrical connections, and the socket set may be needed to remove and replace components.
Step-by-Step Diagnostic Procedure:
1. Retrieve the code using an OBD-II scan tool
2. Check the range switch for damage or corrosion
3. Test the electrical connections for the range switch
4. Inspect the wiring harness for damage
5. If no issues are found with the range switch or wiring, the transmission control module may need to be replaced.
