What Is P1235 Nissan Code
The P1235 Nissan Code is related to the Throttle Position Sensor Circuit Range/Performance. It typically indicates a fault with the fuel leakage or ignition system in the vehicle. These systems are responsible for monitoring and controlling the air-fuel mixture in the engine. When the code is triggered, it means that the throttle position sensor is not functioning correctly, or is not within the specified range. This can result in reduced engine performance and decreased fuel economy. To fix the issue, technicians must inspect and repair any fuel leakage or ignition system issues, and replace any faulty parts. Additionally, they can reset the throttle position sensor to bring it back to its normal range. By addressing these issues, drivers can restore the engine’s performance and fuel economy.
Symptoms of P1235 Nissan Code
Diagnosis of the P1235 code may reveal symptoms such as reduced engine power, poor fuel economy, and rough idle. Along with these symptoms, the check engine light may come on, and the engine may start to surge or hesitate. The driver may also notice a decrease in responsiveness from the throttle. The cause of the P1235 code is usually a faulty ignition system or a malfunctioning throttle position sensor. This sensor is located in the engine and is responsible for monitoring the engine’s air intake and fuel mixture. Poor fuel economy and engine performance can be caused by a faulty ignition system or a malfunctioning throttle position sensor. If the sensor is not working properly, the engine may not be able to maintain the correct fuel/air ratio, resulting in reduced engine power and poor fuel economy.
Causes of P1235 Nissan Code
Faulty ignition systems and malfunctioning throttle position sensors can be the cause of the P1235 code. This code indicates there is an issue with the throttle position sensor circuit range/performance. The engine misfires and sluggish acceleration can be signs that the code is present. A faulty throttle position sensor can cause a wide variety of issues, such as an erratic idle, stalling, and hesitation while accelerating. The engine can also struggle to stay running, especially when the vehicle is idling. Additionally, a malfunctioning throttle position sensor can cause the engine to overwork, leading to increased fuel consumption. To diagnose the issue, an experienced mechanic can use a specialized diagnostic tool to measure the voltage output of the throttle position sensor. If the sensor is functioning properly, the mechanic can then inspect the wiring and connections to ensure they are secure and free of corrosion. It’s important to have the issue properly diagnosed and fixed as soon as possible, as a faulty throttle position sensor can cause long-term damage to the engine.
How to Fix P1235 Nissan Code
A remedy for the P1235 code is to repair the ignition system and replace the malfunctioning throttle position sensor. Troubleshooting strategies should be deployed to ensure a speedy and accurate diagnosis. These include visual inspection, checking for any loose connections, and testing the voltage going to and from the throttle position sensor. In some cases, it may be necessary to remove the sensor and clean it. Further diagnostic procedures, such as scanning for diagnostic trouble codes, should be carried out to confirm the results. Once all these steps have been completed, the throttle position sensor should be replaced if it is found to be malfunctioning. With the right tools and knowledge, this code can be remedied and the vehicle can be back on the road in no time.

Frequently Asked Questions
What Other Codes Can Be Associated With the P1235 Nissan Code?
When it comes to diagnosing a code like P1235, it’s important to consider the other codes that may be associated. Reading diagnostic codes, checking wiring harnesses, and inspecting vacuum lines are all important when attempting to diagnose a code like P1235. Other codes that may be associated include P0120, P0121, P0122, P0123, P0125, P0126, P0127, P0128, P0223, P0224, P0225, P0226, and P0227. These codes can indicate a range of issues from a faulty throttle position sensor to a wiring harness issue. It’s important to identify and diagnose the root cause of the issue to ensure your vehicle runs properly.
Is It Possible to Reset the Code on My Own?
Yes, it is possible to reset the code on your own. To do so, you must first clean the sensor. This can be done with a cloth and a mild cleaning solution. Once the sensor is clean, the computer must be reset. This can be done by disconnecting the battery for a few minutes and then reconnecting it. Doing this will reset the code and the car should be running smoothly again. However, if the issue persists, it is recommended to have the car serviced by a professional.
Can the P1235 Nissan Code Be Caused by a Faulty Throttle Body?
Yes, the P1235 Nissan code can be caused by a faulty throttle body. A faulty throttle body might be the result of a buildup of dirt and debris, or it might have been damaged by a cold air intake or clogged fuel filter. In either case, the throttle body can become stuck or slow to respond, leading to the P1235 code. To fix the code, it is important to clean the throttle body, replace any damaged parts, and/or replace the fuel filter. Doing so can help restore the throttle body to proper working order and eliminate the code.
Are There Any Safety Risks Associated With a P1235 Nissan Code?
Yes, there are safety risks associated with a P1235 Nissan code. If the throttle position sensor is malfunctioning, it can cause the vehicle to fail to respond to acceleration and deceleration. This can lead to an increased risk of a crash or other dangerous situation. Additionally, if the wiring is faulty, this can create overheating issues that can damage the vehicle and present a fire hazard. It’s important to have the issue addressed by a qualified mechanic as soon as possible to ensure the safety of you and your passengers.
How Often Should I Check My Throttle Position Sensor Circuit?
It is important to check your throttle position sensor circuit regularly to ensure that it is functioning properly.
