P1235 Code Nissan:
The P1235 code in a Nissan vehicle indicates a problem with the throttle position sensor (TPS) circuit. This code is triggered when the TPS circuit is not functioning within the expected range or performance level. The TPS is responsible for sending signals to the engine control module (ECM) to adjust the throttle opening and fuel injection based on the driver’s input. When the TPS circuit is not working properly, it can cause issues with the engine’s performance, such as poor acceleration, stalling, or even failure to start.
To fix the P1235 code, the first step is to check the TPS circuit for any damage or loose connections. If there are no visible issues, the TPS itself may need to be replaced. It is also important to check the ECM for any related faults or malfunctions. In some cases, a software update or reprogramming may be necessary to resolve the issue. It is recommended to have a professional mechanic diagnose and repair the P1235 code to ensure proper and safe repairs.
Signs and Symptoms of P1235 Code Nissan
The P1235 code in Nissan vehicles indicates a problem with the throttle position sensor (TPS) circuit. This sensor is responsible for monitoring the position of the throttle and sending signals to the engine control module (ECM) to adjust the air-fuel mixture and engine performance accordingly. When the TPS circuit is not functioning properly, it can cause a range of symptoms that can affect the drivability and performance of the vehicle. Here are some of the most common signs and symptoms of the P1235 code in Nissan vehicles:
- Check Engine Light: The most obvious symptom of the P1235 code is the illumination of the check engine light on the dashboard. This light is triggered by the ECM when it detects a problem with the TPS circuit.
- Reduced Power: A faulty TPS circuit can cause the engine to lose power and acceleration. This can be especially noticeable when trying to accelerate from a stop or when passing other vehicles on the highway.
- Stalling: In some cases, a malfunctioning TPS circuit can cause the engine to stall or shut off completely. This can be dangerous if it happens while driving at high speeds or in heavy traffic.
- Erratic Idle: A faulty TPS circuit can also cause the engine to idle erratically or stall when coming to a stop. This can make it difficult to drive in traffic or park the vehicle.
- Poor Fuel Economy: When the TPS circuit is not functioning properly, it can cause the engine to run rich or lean, which can lead to poor fuel economy and increased emissions.
If you experience any of these symptoms in your Nissan vehicle, it is important to have it diagnosed and repaired as soon as possible. Ignoring the P1235 code can lead to further damage to the engine and other components, which can be costly to repair. A qualified mechanic can use diagnostic tools to pinpoint the exact cause of the problem and recommend the appropriate repairs to get your vehicle back to optimal performance.This response was truncated by the cut-off limit (max tokens).

P1235 Code Nissan:
If you own a Nissan vehicle and the check engine light is on, you may have encountered the P1235 code. This code indicates that there is an issue with the throttle position sensor circuit range or performance. The throttle position sensor (TPS) is responsible for monitoring the position of the throttle valve and sending signals to the engine control module (ECM) to adjust the air-fuel mixture and engine speed. When the TPS circuit is not functioning properly, it can cause a variety of problems with the engine’s performance.
- Failed TPS: The most common cause of the P1235 code is a failed TPS. Over time, the TPS can wear out or become damaged, causing it to send incorrect signals to the ECM. This can result in poor engine performance, stalling, and difficulty starting the vehicle.
- Wiring Issues: Another possible cause of the P1235 code is wiring issues. If the wiring that connects the TPS to the ECM is damaged or corroded, it can cause the TPS to malfunction. This can result in a variety of engine problems, including poor acceleration and stalling.
- ECM Malfunction: In some cases, the P1235 code may be caused by a malfunctioning ECM. If the ECM is not receiving the correct signals from the TPS, it may not be able to adjust the engine’s performance properly. This can result in poor acceleration, stalling, and other engine problems.
- Throttle Body Issues: The throttle body is responsible for regulating the amount of air that enters the engine. If the throttle body is dirty or damaged, it can cause the TPS to malfunction. This can result in poor engine performance, stalling, and difficulty starting the vehicle.
- Other Causes: Other possible causes of the P1235 code include a faulty accelerator pedal position sensor, a vacuum leak, or a malfunctioning fuel injector.
If you are experiencing the P1235 code, it is important to have your vehicle diagnosed by a qualified mechanic. They will be able to determine the exact cause of the problem and recommend the appropriate
Fixes for P1235 Code Nissan
The P1235 code in Nissan vehicles indicates a problem with the throttle position sensor circuit range or performance. This can cause issues with the engine’s performance, including stalling, hesitation, and poor acceleration. Here are some possible fixes for this code:
- Replace the throttle position sensor: The most common cause of the P1235 code is a faulty throttle position sensor. This sensor is responsible for sending information to the engine control module about the position of the throttle. If it is not working properly, it can cause the engine to run poorly. Replacing the sensor should fix the problem.
- Check the wiring and connections: Sometimes, the problem may not be with the sensor itself, but with the wiring or connections leading to it. Check for any damaged or corroded wires, and make sure all connections are secure. Repair or replace any damaged components as needed.
- Inspect the throttle body: If the throttle body is dirty or clogged, it can cause problems with the throttle position sensor. Remove the throttle body and clean it thoroughly with a carburetor cleaner. Make sure to also clean the throttle plate and the idle air control valve.
- Check the engine control module: In rare cases, the problem may be with the engine control module itself. If all other components have been checked and are functioning properly, the ECM may need to be replaced.
- Perform a throttle relearn procedure: After replacing the throttle position sensor or making any other repairs, it may be necessary to perform a throttle relearn procedure. This involves resetting the throttle body to its default position and allowing the ECM to relearn the correct throttle position. Consult the vehicle’s owner’s manual or a professional mechanic for instructions on how to perform this procedure.
