The dreaded check engine light – it’s a sight no car owner wants to see illuminated on their dashboard. For owners of a 2007 Nissan Altima, this light often signals that your vehicle’s On-Board Diagnostic (OBD) system has detected an issue. Understanding what these OBD2 codes mean is the first step in diagnosing and resolving car problems efficiently. This guide will help you navigate the world of 2007 Nissan Altima Obd2 Codes, providing insights into common codes and potential fixes.
Your 2007 Nissan Altima is equipped with an OBD-II system, a standardized system used in most vehicles today. When a problem arises, the system generates a trouble code, which can be accessed using an OBD-II scanner. These codes are designed to help technicians pinpoint the source of the problem, but with a little understanding, you too can gain valuable insight into your vehicle’s health.
Below is a detailed list of common OBD-II trouble codes that your 2007 Nissan Altima might display. This list expands upon the original article, providing more context and potential causes specifically relevant to the 2007 Altima model where possible.
| Code | Common Problems That Trigger This Code |
|---|---|
| P0010 | Camshaft Position Actuator A Circuit (Bank 1): This code often indicates issues within the Variable Valve Timing (VVT) system. Potential problems for a 2007 Nissan Altima could include a malfunctioning VVT solenoid, wiring problems in the actuator circuit, or in rarer cases, a Powertrain Control Module (PCM) failure. It’s worth checking the wiring and connections to the VVT solenoid first. |
| P0011 | Camshaft Position – Timing Over-Advanced or System Performance (Bank 1): For a 2007 Nissan Altima, this code can suggest problems with the engine timing. Common culprits include a faulty camshaft variable timing solenoid, low engine oil level or pressure (critical for VVT operation), incorrect engine timing, using the wrong type of engine oil, a failing variable valve timing actuator, or even a worn timing chain, which can be a concern in higher mileage vehicles. Regular oil changes with the correct viscosity are crucial for preventing this. |
| P0012 | Camshaft Position – Timing Over-Retarded (Bank 1): Similar to P0011, this code in a 2007 Altima points to timing issues, but specifically timing that is retarded. The causes are often the same as P0011: camshaft variable timing solenoid failure, low engine oil level, incorrect engine timing, incorrect engine oil, variable valve timing actuator problems, or a worn timing chain. |
| P0013 | Camshaft Position Actuator B Circuit (Bank 1): This mirrors P0010 but refers to a different actuator in the VVT system. Again, consider a faulty VVT solenoid, wiring issues, or PCM failure as potential causes in your 2007 Nissan Altima. |
| P0014 | Camshaft Position – Timing Over-Advanced or System Performance (Bank 1): Functionally the same as P0011, but may relate to a different part of the VVT system. The diagnostic steps for a 2007 Altima are identical to P0011. |
| P0101 | Mass Air Flow (MAF) Sensor Circuit Range/Performance: This code is common across many vehicles, including the 2007 Nissan Altima. It signals that the MAF sensor isn’t reading airflow correctly. Check for large vacuum leaks – inspect intake boots, PCV hoses, and intake manifold gaskets. A defective MAF sensor itself is a possibility, as are wiring problems in the MAF sensor circuit. Less common, but still possible, are a defective Barometric Pressure Sensor, a dirty MAF sensor element, or even the need for a PCM software update. Cleaning the MAF sensor with a specialized cleaner might resolve the issue. |
| P0102 | Mass Air Flow (MAF) Sensor Circuit Low Input: This code on your 2007 Altima usually means the MAF sensor is sending a low voltage signal, indicating low airflow. The most common reasons are a disconnected or damaged MAF sensor, wiring issues (loose or corroded terminals), or a faulty MAF sensor. Ensure the MAF sensor connector is securely plugged in and check for any visible wire damage. |
| P0113 | Intake Air Temperature Sensor Circuit High Input: This indicates a high voltage reading from the Intake Air Temperature (IAT) sensor. For a 2007 Nissan Altima, consider a defective IAT sensor, a dirty air filter restricting airflow (though less directly related to the sensor itself), a defective MAF sensor (as the IAT sensor is often integrated), or wiring/connection problems with the IAT sensor. |
| P0128 | Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature): This code suggests the engine coolant is not reaching the expected operating temperature in your 2007 Altima within a reasonable timeframe. A defective engine thermostat (stuck open) is the most likely cause. Other possibilities include a defective Engine Coolant Temperature Sensor, a defective IAT sensor, cooling system issues, low coolant level, dirty coolant, or cooling fans running constantly. |
| P0135 | O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1): This code relates to the oxygen sensor heater circuit. Potential causes for a 2007 Nissan Altima include a defective O2 sensor or its heater circuit, exhaust leaks, intake air leaks, low fuel pressure, a defective Engine Coolant Temperature Sensor, wiring problems, PCM software issues, or a faulty PCM. Examine the wiring to the O2 sensor for damage and check for exhaust leaks near the sensor. |
| P0171 | System Too Lean (Bank 1): A lean condition means there’s too much air and not enough fuel in the engine. On a 2007 Altima, this could be due to vacuum leaks (intake manifold gaskets, hoses), a faulty MAF sensor, a plugged fuel filter or weak fuel pump, or dirty fuel injectors. Less commonly, it could be a PCM software issue. Checking for vacuum leaks is a good starting point. |
| P0174 | System Too Lean (Bank 2): Same as P0171, but refers to Bank 2 (if applicable on your engine configuration). The causes and troubleshooting steps for a 2007 Nissan Altima are identical to P0171. |
| P0200 | Injector Circuit Malfunction: This indicates a general problem with the fuel injector circuit. For a 2007 Altima, consider a defective fuel injector, wiring/connection problems, a plugged injector, or dirt in the injector. |
| P0201 – P0206 (and others in sequence) | Injector Circuit Malfunction – Cylinder Specific (Cylinder 1, 2, etc.): These codes pinpoint a specific cylinder’s injector circuit. The causes are the same as P0200, but focused on the injector for the specified cylinder in your 2007 Nissan Altima. |
| P0300 | Random/Multiple Cylinder Misfire Detected: This is a common misfire code. For a 2007 Nissan Altima, potential causes are numerous: worn spark plugs, ignition wires, coils, distributor cap/rotor (though less common on newer vehicles), incorrect ignition timing, vacuum leaks, low fuel pressure, EGR system issues, a defective MAF sensor, crankshaft/camshaft sensor problems, throttle position sensor issues, or even mechanical engine problems like low compression, head gasket leaks, or valve problems. Start with basic tune-up items like spark plugs and wires. |
| P0301 – P0306 (and others in sequence) | Cylinder # Misfire Detected (Cylinder 1, 2, etc.): These codes specify a misfire in a particular cylinder. The causes are similar to P0300, but focused on the specific cylinder. Isolating the misfiring cylinder can help narrow down the problem in your 2007 Altima. |
| P0401 | Exhaust Gas Recirculation Flow Insufficient Detected: This code indicates insufficient EGR flow. For a 2007 Nissan Altima, check for restrictions in the EGR passages (carbon buildup), a defective EGR valve, vacuum or electrical signal problems to the EGR valve, a malfunctioning EGR vacuum solenoid, or issues with sensors that provide feedback on EGR system performance (MAP, DPFE, EVP, EGR Temperature Sensor). |
| P0420 | Catalyst System Efficiency Below Threshold (Bank 1): This code suggests the catalytic converter efficiency is low. Possible causes for a 2007 Altima include an inefficient catalytic converter itself, defective front or rear oxygen sensors, or engine misfires. Misfires can damage the catalytic converter over time. |
| P0430 | Catalyst System Efficiency Below Threshold (Bank 2): Same as P0420, but for Bank 2 (if applicable). The diagnosis and potential issues for a 2007 Nissan Altima are the same as P0420. |
| P0440, P0441, P0442, P0455 | Evaporative Emission Control System (EVAP) Faults: These codes relate to different EVAP system leaks or malfunctions. Common causes on a 2007 Nissan Altima include a missing or defective fuel cap, damaged fuel filler neck, torn or punctured EVAP hoses, a defective fuel tank sending unit gasket, a split carbon canister, or problems with EVAP vent or purge valves. Always start by checking the fuel cap. |
| P0500, P0501 | Vehicle Speed Sensor (VSS) Malfunction: These codes indicate problems with the Vehicle Speed Sensor. For a 2007 Altima, suspect a defective VSS, speedometer issues, wiring or connector problems, CAN bus communication faults, or a defective VSS drive gear in the transmission or differential. |
| P0505, P0506, P0507 | Idle Air Control (IAC) System Malfunctions: These codes relate to the idle air control system, which regulates engine idle speed. Potential issues for a 2007 Nissan Altima include a defective IAC motor, vacuum leaks, carbon buildup in the throttle body, or a defective power steering pressure switch (in some cases). Cleaning the throttle body and IAC valve area can sometimes resolve idle issues. |
| P0600 – P0605, P0610, P062F, P0641, P0651, P0661, P0691, P0693, P0700, P0705, P0706, P0720, P0730, P0841, P0842, P0845, P0846, P0847, P0901, P0935, P0942, P0944, P0961, P0A08, P0A0D, P0A0F, P0A7F, P0A80, P0B22, P0B24, P0B26, P0B28, P0B30, P0C00, P0C09, P0C11, P0C14, P0C15, P2000, PP2002, P2004, P2006, P2101, P2122, P2135, P2138, P2181, P2210, P2213, P2237, P2238, P2251, P2302 – P2310, P2401, P2402, P2422, P2431, P2432, P2500 – P2503, P2509, P250C, P2601, P2607, P2609, P2610, P2614, P2706, P2711, P2714, P2716, P2723, P2803, P2806, P2809, P2810, P2815, P2A00 – P2A04, P2BA8, P3000, P3100, P3400, P3401, B0081, C0040, U0001, U0073, U0100, U0107, U0121 | Various System Faults: These codes cover a wide range of potential issues, from Powertrain Control Module (PCM) failures and Transmission Control Module (TCM) problems to sensor malfunctions, wiring issues, and mechanical failures. Many of these codes are less common but can still occur in a 2007 Nissan Altima. Accurate diagnosis often requires professional scan tools and expertise. |
