By Ezra Lane Your Nissan displaying the P1135 code signals a problem with the intake valve timing control on Bank 2, typically stemming from a faulty solenoid or wiring issues. You'll likely notice reduced engine power, rough idling, or increased fuel consumption. To fix this, you should use an OBD-II scanner to verify the code, inspect and possibly replace the solenoid, and repair any defective wiring. Resetting the engine control module is also crucial for restoring function. Prompt action prevents further complications, ensuring your vehicle regains optimal performance. Understanding this will help you address the issue more effectively.
P1135 Nissan Code Meaning
The P1135 code in a Nissan indicates an issue with the Intake Valve Timing Control system on Bank 2, often due to a faulty solenoid or wiring.
Diagnose the root cause, replace or repair components, and reset the engine control module to restore performance.
Error Code P1135 Symptoms
If your Nissan shows a P1135 error code, you might notice a few issues with how your car runs:
- Less Engine Power:
- Your car might feel slow when you try to speed up. This happens because the intake valve timing is off, making it hard for the engine to get the air it needs to run well, which lowers power.
- Rough Idling and Stopping:
- The car might shake when it's not moving or even stop running while driving. This is because the timing issue affects the way the intake valves work, causing the engine to not run smoothly.
- Using More Fuel:
- You might find that your car is using more gas than usual. When the timing is wrong, the engine can't burn fuel efficiently, so it needs more gas to keep going.
A check engine light usually comes on when these problems occur.
You might also notice the engine misfiring when you try to accelerate, which can make driving harder.
Causes of Nissan P1135 Fault Code
If your Nissan shows the P1135 code, it usually means there's a problem with the intake valve timing control solenoid. This can affect how your car runs and uses fuel. Here are some common reasons why this happens:
1. Bad Intake Valve Timing Control Solenoid
This part helps adjust when the intake valves open and close. If it doesn't work right, the timing can be off, causing performance problems.
2. Wiring Problems
If wires are damaged or shorted, the solenoid mightn't get the right signals to work. This can trigger the P1135 code because the solenoid isn't doing its job.
3. Mechanical Issues in the Timing Control System
Parts can wear out or break in the timing control system. Things like dirty engine oil can block the solenoid, or overheating can harm the system. These issues can bring up the fault code.
Identifying these causes is key for fixing the problem effectively.
Tools Needed to Diagnose
To figure out the Nissan P1135 code, you'll need a few tools. These tools will help you find out what's wrong and fix it.
1. OBD-II Scanner
Get a good OBD-II scanner. It should be able to read Nissan codes. This scanner will show if the P1135 code is active and if there are more codes to check.
2. Multimeter
Use a multimeter to test wires. It checks if wires are working right. This helps find electrical issues that might cause the code.
3. Hand Tools
Have some basic tools like wrenches and screwdrivers. These will help you look at or change parts if needed.
Also, keep a repair manual for your Nissan. It will guide you through steps and provide details on your car's system.
How to Fix P1135 Nissan Error Code – Step by Step
Step 1:
Begin by connecting an OBD-II scanner to your Nissan to confirm the presence of the P1135 error code and check for any additional related trouble codes.
Step 2:
Inspect the intake valve timing control solenoid for any signs of damage or malfunction.
Make sure to also examine the wiring and electrical connections to the solenoid for fraying, corrosion, or loose connections.
Step 3:
If you identify that the solenoid is faulty, proceed to replace it.
Take care to repair any damaged wiring at the same time to ensure proper functionality of the system.
Step 4:
Once the solenoid is replaced and the wiring is fixed, reset the engine control module.
This step is necessary to clear the trouble codes from the system.
Step 5:
Common Diagnosis Mistakes
Why do some technicians miss diagnosing the P1135 Nissan code correctly? It's often due to haste or overlooking key steps. Here are three common mistakes:
- Neglecting Basic Checks:
- Sometimes, a simple look at the intake valve timing control solenoid is skipped.
- Since this is often the main issue, check it first before exploring other possibilities.
- Forgetting Electrical Inspections:
- Don't just focus on the solenoid.
- Also, check for any wiring problems or electrical faults.
- Making sure the circuit is intact can prevent misdiagnosis and avoid wasting money.
- Ignoring Oil Issues:
- Contaminated engine oil can seem like a different problem.
- Ensure that you aren't mixing up the effects of dirty oil with solenoid or timing troubles.
P1135 Nissan Repair Cost
If you're dealing with a P1135 Nissan code, fixing it can cost between $200 and $500. This range depends on the problem's nature and your car type.
Most of the cost usually comes from replacing a bad intake valve timing control solenoid. This part is key to how your engine runs, so it's not cheap, and neither is the labor to fix it.
Labor costs vary by location and mechanic. Urban areas tend to have higher charges than rural ones. The cost also depends on your Nissan model. Some models might need more work or pricier parts.
Electrical problems, like wiring issues, can make repairs more complicated and costly. These may need extra checks, adding to the expense.
Always talk to a professional mechanic for a detailed estimate. They can give you a breakdown of parts and labor for your car, helping you avoid unexpected costs.
Related Error Codes on Nissan
When fixing a P1135 error in a Nissan, you might see other codes too. These codes can help identify more problems. For example, P0011, P0012, and P0021 relate to issues with the engine's timing. They point to problems with how the engine valves open and close.
You might also find P1168 and P1169 if there's a problem with the fuel system or air intake. These affect how well the engine runs.
Sometimes, P0420 appears with P1135, which involves emissions. It suggests the catalytic converter might not be working well. Here's a quick look at some related codes:
| Code | Description |
|---|---|
| P0011 | "A" Camshaft Position – Timing Over-Advanced |
