DTC P0037 Infiniti

Description

HYBRID MODEL CAUTION: Hybrid systems use very high-voltage battery systems. Before starting any service work involving the battery system, turn the ignition switch OFF and then remove the service plug from pocket in the trunk. After removing the service plug, wait 10 minutes before touching any of the high-voltage connectors and terminals. Note: On V6 and V8 engines, this applies to Bank 1. The current amperage in the heated oxygen sensor 2 heater circuit is out of the normal range. (An excessively low voltage signal is sent to ECM via the heated oxygen sensor 2 heater. )
