You have a bad sensor at one of the tires that need replacing that operates ABS and traction control. If you take it in to a shop it will run $130 but they can find which sensor is causing the problem. But if you do it you might have to replace all 4 sensors to make sure you got the right one. Every hard to diagnoses. Its better for the shop cause they can get electrical read outs for each sensor.
SOURCE: 2005 pontiac grand prix, code p0641 came on. What
DTC P0641 The powertrain control module (PCM) provides a 5-volt reference to the
following sensors:
The throttle position (TP) sensor 1
The accelerator pedal position (APP) sensor 2
The engine cooling fan speed sensor
The AC pressure sensor
The fuel tank pressure (FTP) sensor
The oil pressure sensor (OPS)
The PCM monitors voltage on the 5-volt reference circuit. If the voltage
is higher or lower than required, DTC P0641 will set.
Conditions for Setting the DTC
The PCM detects a voltage that is higher or lower than required on the
5-volt reference circuit. The above condition is present for 1 second. Action Taken When the DTC Sets The control module illuminates the malfunction indicator lamp (MIL) when
the diagnostic runs and fails. The control module records the operating conditions at the time the
diagnostic fails. The control module stores this information in the
Freeze Frame/Failure Records.
Conditions for Clearing the MIL/DTC The control module turns OFF the malfunction indicator lamp (MIL) after 3
consecutive ignition cycles that the diagnostic runs and does not fail.
A current DTC, Last Test Failed, clears when the diagnostic runs and
passes. A history DTC clears after 40 consecutive warm-up cycles, if no failures
are reported by this or any other emission related diagnostic. Clear the MIL and the DTC with a scan tool.
Yes i can be dangerous, depending which issues mentioned above has triggered the code such as a faulty gas peddle position sensor. the code can also cause a reduced engine power to activate.
Thank you for using Fixya and best advice is to have the dealer address these issues. A tech 2 scanner would be needed to address the P0641 DTC code.
