DTC Advanced Diagnostics: P060B (3.0L Engine)

DTC P060B: Powertrain Control Module (PCM) AD Processing Performance

General Description

Courtesy of HONDA, U.S.A., INC.

The A/D converter is checked with using the self-diagnostic function of the microcomputer (MCU) that is built into the powertrain control module (PCM). The voltage generator in the MCU generates a reference voltage to compare with the voltage after the conversion of A/D. If the A/D converter voltage does not match with the reference voltage, the PCM detects a malfunction and stores a DTC.

Malfunction Threshold

The A/D converter voltage is inconsistent with the reference voltage.

Possible Cause

NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.

PCM internal circuit failure (A/D converter)

Diagnosis Details

Conditions for setting the DTC

When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, the freeze data, and the on-board snapshot are stored in the PCM memory.

Conditions for clearing the DTC

The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, the freeze data, and the on-board snapshot can be cleared with the scan tool clear command.
