1996 Nissan Maxima P0150 P0136 P0105 P0130: Diagnosis and Fix Tips for Engine Shutdown at Stops
I own a 1996 Nissan Maxima with a V6 engine and automatic transmission. The car has started shutting down intermittently during stops, but it consistently restarts on its own. I've already replaced the knock sensor, starter, airflow sensor, battery cables, and several other minor components. While the symptoms have improved in frequency, the issue still occurs. After troubleshooting, my OBD-II scanner shows multiple fault codes: P0150 (O2 Sensor Heater Circuit Malfunction - Bank 1), P0136 (O2 Sensor Signal Malfunction - Bank 1), P0105 (MAF Sensor Circuit Fault), and P0130 (O2 Sensor Heater Circuit Malfunction - Bank 1). I've cleared these codes, driven the car around, and then new codes appear: P0440 (EVAP System Leak Detected) and P0446 (EVAP Canister Vent Control Malfunction). After clearing those, the system returns with a mix of codes including P040 (likely a typo or misread), P0150, P0130, P0440, P0446, and P0174 (Rich Fuel Trim Bank 1). I previously received an EGR-related code that I no longer have documentation for. The car runs well under normal conditions—strong engine performance and excellent fuel economy—but when it begins to act up, letting it sit for about 30–60 minutes often resolves the issue. I’ve been advised to try throttle spray, but I’m unsure of its exact application (e.g., behind the MAF sensor). While this temporarily improves performance, it doesn’t resolve the root cause. My current mechanic friend has suggested checking the distributor assembly and related components. Given that similar issues in older Nissan Maximas are often linked to ignition system wear or temperature-dependent performance, I’m considering a deeper inspection of wiring harnesses, O2 sensors, and EVAP system integrity. I'm seeking community input on how to diagnose this intermittent shutdown issue—especially given the cluster of OBD-II codes and the pattern of symptoms that resolve after idle time. Any insights into possible root causes or diagnostic steps would be greatly appreciated.
I'll check for replies to my post soon—don't have 24-hour internet access. Thanks in advance!
