Nissan - P155b00

When the Check Engine light illuminates on a vehicle's dashboard, it can cause immediate stress. For Nissan owners, pulling the codes via an On-Board Diagnostics (OBD-II) scanner might reveal a highly specific manufacturer code: .

You will need a (e.g., Autel, Launch, or Nissan CONSULT). Generic OBD2 code readers won’t show internal resistance values.

Start with a thorough test of the 12-volt battery using a multimeter and a load tester: nissan p155b00

In more severe cases, especially in electric vehicles like the Nissan Leaf, the system may enter a to protect the battery and other critical components. This might involve limiting vehicle speed, restricting charging, or in extreme cases, preventing the vehicle from driving at all.

A: Mostly. It appears on the Note, Serena, X-Trail (T32 Hybrid), and Infiniti M35h / QX60 Hybrid. It rarely appears on the Leaf because the Leaf’s battery architecture is different (no internal resistance monitoring in the same way). When the Check Engine light illuminates on a

In modern electronic engine management systems, components like the throttle position sensor, the electronic throttle actuator, and turbocharger wastegates operate using "self-learning" parameters. The Engine Control Module (ECM) establishes baseline positions (the "zero" or resting point) when the ignition is turned on.

The vehicle will fail inspections due to elevated hydrocarbon emissions and incomplete OBD-II readiness monitors. Common Causes Generic OBD2 code readers won’t show internal resistance

The total repair cost depends on the underlying cause. Below are the typical repair scenarios and their associated costs. Unless otherwise noted, costs are estimates based on average independent shop labor rates.
