1999 Nissan Pathfinder P1320 Code: Diagnosis and Solutions

The 1999 Nissan Pathfinder P1320 code signifies a malfunction within the ignition signal circuit. This article, brought to you by CARDIAGTECH.NET, will provide a comprehensive guide to diagnosing and resolving this issue, empowering you with the knowledge to get your Pathfinder back on the road. Learn about troubleshooting techniques and explore preventative maintenance to avoid future occurrences.

1. Understanding the P1320 Code on Your 1999 Nissan Pathfinder

The P1320 code in a 1999 Nissan Pathfinder indicates a problem with the primary ignition signal circuit, specifically with the signal being sent from the distributor or ignition module to the Engine Control Unit (ECU). This signal is crucial for the ECU to accurately time the fuel injection and ignition events, ensuring proper engine operation. When the ECU detects an irregularity or complete absence of this signal, it triggers the P1320 code, illuminating the malfunction indicator lamp (MIL), commonly known as the check engine light. Addressing this code promptly is essential to prevent potential engine damage and maintain optimal vehicle performance.

1.1. Decoding the P1320 Error Message

The P1320 code isn’t just a random collection of characters; it’s a precise indicator of a problem within your 1999 Nissan Pathfinder’s ignition system. It essentially screams, “Hey, the ECU isn’t receiving the correct signal from the ignition system!” Understanding what this signal represents is key. The ECU relies on this signal to synchronize fuel injection and spark timing. When this signal is disrupted, the engine’s performance suffers. This means rough idling, misfires, reduced power, or even a complete no-start condition. Ignoring this code can lead to more severe issues down the road.

1.2. Symptoms Associated with the P1320 Code

Recognizing the symptoms associated with the P1320 code is crucial for early detection and prevention of further damage. These symptoms can range from subtle performance issues to more obvious signs of engine malfunction.

Check Engine Light: This is the most obvious indicator. The light will illuminate on your dashboard, signaling that the ECU has detected a problem.
Rough Idling: The engine may idle unevenly or stall, especially when the vehicle is stopped.
Misfiring: You might feel a jerking or sputtering sensation, indicating that one or more cylinders are not firing correctly.
Reduced Power: The engine may lack its usual responsiveness, especially during acceleration.
Difficulty Starting: The engine may take longer to start than usual, or it may not start at all.
Poor Fuel Economy: The engine may consume more fuel than normal due to inefficient combustion.
Stalling: The engine may suddenly stall while driving.

These symptoms shouldn’t be ignored. Prompt diagnosis and repair can save you from costly repairs down the line.

1.3. Common Causes of the P1320 Code

Several factors can trigger the P1320 code in your 1999 Nissan Pathfinder. Pinpointing the root cause is the first step towards a successful repair.

Faulty Ignition Coil: A malfunctioning ignition coil can fail to deliver the necessary spark to the spark plugs.
Bad Distributor: Issues within the distributor, such as a faulty pickup coil or damaged components, can disrupt the ignition signal.
Wiring Issues: Damaged, corroded, or loose wiring in the ignition circuit can interrupt the signal flow.
Faulty Crankshaft Position Sensor (CKP): Although less common, a failing CKP sensor can sometimes trigger the P1320 code.
Faulty Camshaft Position Sensor (CMP): Similar to the CKP sensor, a malfunctioning CMP sensor can also contribute to the problem.
ECU Issues: In rare cases, a faulty ECU can misinterpret or fail to process the ignition signal correctly.

Understanding these potential causes empowers you to approach the diagnostic process systematically.

2. Step-by-Step Diagnosis of the P1320 Code

Diagnosing the P1320 code requires a methodical approach. Following these steps will help you identify the culprit and get your Pathfinder running smoothly again.

2.1. Initial Inspection

Before diving into complex diagnostics, start with a thorough visual inspection.

Check Wiring: Examine all visible wiring connected to the ignition coil, distributor, CKP sensor, and CMP sensor. Look for any signs of damage, such as frayed wires, cracks, or corrosion. Pay close attention to connectors, ensuring they are securely fastened.
Inspect Fuses: Locate the fuse box and check the fuses related to the ignition system. Replace any blown fuses with the correct amperage rating.
Examine the Distributor Cap and Rotor: Remove the distributor cap and inspect it for cracks, carbon tracking, or corrosion. Check the rotor for damage or wear.

This initial inspection can often reveal obvious problems that can be easily rectified.

2.2. Using an OBDII Scanner

An OBDII scanner is an indispensable tool for diagnosing automotive problems.

Connect the Scanner: Plug the scanner into the OBDII port, typically located under the dashboard on the driver’s side.
Read the Codes: Turn the ignition key to the “on” position (without starting the engine) and allow the scanner to read the stored codes. Record all codes present, including the P1320 code.
Clear the Codes: After recording the codes, clear them from the ECU’s memory. This allows you to monitor if the P1320 code reappears after testing.

This step provides valuable information about the nature and frequency of the problem.

2.3. Testing the Ignition Coil

The ignition coil is a prime suspect when dealing with the P1320 code. Testing its functionality is crucial.

Visual Inspection: Check the ignition coil for any visible signs of damage, such as cracks, leaks, or corrosion.
Resistance Test: Use a multimeter to measure the resistance of the primary and secondary windings of the ignition coil. Compare your readings to the manufacturer’s specifications. Significant deviations indicate a faulty coil.
Spark Test: Carefully remove a spark plug and connect it to the ignition coil. Ground the spark plug against the engine block and have someone crank the engine. Observe whether a strong, consistent spark is present.

If the ignition coil fails any of these tests, replacement is necessary. At CARDIAGTECH.NET, we offer a wide selection of high-quality ignition coils to fit your 1999 Nissan Pathfinder. Contact us at +1 (641) 206-8880 for expert advice and assistance.

2.4. Evaluating the Distributor

The distributor plays a vital role in the ignition system.

Check the Pickup Coil: The pickup coil inside the distributor generates the signal that triggers the ignition coil. Use a multimeter to test the resistance of the pickup coil. Compare your readings to the manufacturer’s specifications.
Inspect the Distributor Shaft: Check for any signs of wear or damage to the distributor shaft. Excessive play can disrupt the timing and signal generation.
Test the Hall Effect Sensor: Some distributors use a Hall effect sensor to generate the ignition signal. Use a multimeter or oscilloscope to test the sensor’s output.

A faulty distributor can cause a variety of ignition problems, including the P1320 code.

2.5. Examining the Crankshaft and Camshaft Position Sensors

The CKP and CMP sensors provide crucial information to the ECU about the engine’s position and timing.

Visual Inspection: Check the sensors and their wiring for any signs of damage.
Resistance Test: Use a multimeter to measure the resistance of the sensors. Compare your readings to the manufacturer’s specifications.
Output Test: Use an oscilloscope to observe the sensor’s output signal while the engine is running. Look for any irregularities or dropouts in the signal.

Faulty CKP or CMP sensors can disrupt the ignition timing and trigger the P1320 code.

2.6. Tracing Wiring and Connections

Wiring issues are a common cause of the P1320 code.

Continuity Test: Use a multimeter to perform a continuity test on all wiring connected to the ignition coil, distributor, CKP sensor, CMP sensor, and ECU. This ensures that there are no breaks or shorts in the wiring.
Voltage Test: Check the voltage at the ignition coil and sensors to ensure that they are receiving the correct voltage.
Inspect Connectors: Carefully inspect all connectors for corrosion, damage, or loose connections. Clean or replace any damaged connectors.

Thoroughly checking the wiring and connections can often reveal the source of the problem.
