P2158 code definition

Vehicle Speed Sensor 'B'

What the P2158 code means

This trouble code indicates that the powertrain control module has detected a variation in the reference voltage of the vehicle speed sensor 'B' in reference to the wheel speed sensors on the vehicle. This variation could be higher, lower, or a complete cut out of the reference voltage all together.

What are the causes of the P2158 code?

Some of the potential causes of this trouble code could be:

  • A faulty vehicle speed sensor may be present.

  • A faulty wheel speed sensor may exist.

  • Damaged wiring or connectors that are associated with the vehicle speed sensor or the wheel speed sensor would be contributing to this trouble code.

  • The incorrect size tires or wheels affixed to the vehicle may also cause this issue.

  • The powertrain control module may be malfunctioning as a cause of this issue.

  • A broken or faulty ABS tone ring could cause this issue as well.

What are the symptoms of the P2158 code?

Some of the symptoms of this trouble code that the driver may experience would include:

  • The ABS system may be deactivated and the ABS light may be illuminated.
  • The speedometer and the odometer could produce inaccurate readings.
  • The tachometer may behave inappropriately.
  • The transmission may shift incorrectly if it is an automatic transmission.

How does a mechanic diagnose the P2158 code?

A mechanic may begin diagnosing this trouble code by locating the vehicle speed sensor and the wheel speed sensors and checking them and their circuitry for damages. This inspection would also include looking over the ABS tone rings and checking the wheel bearings for play. If any issues are found during this inspection, they should be resolved before any further diagnostics could take place. If the wheels and tires are the incorrect size, this issue would also need to be resolved at this time. If no issues are found during the inspection of all of these parts, the powertrain control module would be tested with a high tech scan tool to test for proper function.

Common mistakes when diagnosing the P2158 code

It is very easy to skip over the obvious. It is very important to check that the wheel and tire size are correct for the vehicle. The powertrain control module is programmed to accept a certain tire size and if this is not correct, other systems of the vehicle may perform improperly.

How serious is the P2158 code?

This trouble code would be very serious depending on the exact symptoms. If the transmission is misbehaving, the issue would be considered very serious and should be resolved as soon as possible. If the only symptom of this issue is a malfunctioning gauge cluster, this issue would be considered less serious and could be put on the back burner for a short time. Just with all Check Engine Lights, it is always best to have the issue resolved at the earliest possible opportunity.

What repairs can fix the P2158 code?

Repairs that can potentially resolve the issues caused by this trouble code would include:

Additional comments regarding the P2158 code

If the gauges are not reading correctly due to this trouble code, it would be a good idea to drive slightly slower in order to reduce the chances of a speeding ticket and ensure that you are driving at safe speeds.
