My VSA with /!\ light stays on most of the time, sometimes goes off. Occasionally when accelerating (dry ground, no spinning of tires) i will hear, and feel a rather loud grinding noise directly under my brake pedal, not the usual sound of the VSA engaging. If I have cruise control engaged it will shut off and I cannot turn it back on. Mechanic says the code indicates that there is a communication issue with the compute due to low oil, but I don't see why that would cause the grinding and subsequent loss of cruise control. Any ideas? Has anyone else experienced this?

could be a faulty brake pedal switch. Are you able to replace it with another tsx one to check?

seems like if it were that either my brake lights would be on all the time or would never turn on. Also I am concerned about the occasional clunking/grinding sound coming from under my brake pedal.

vsa /!\ on means your traction controls off. Are you throwing any codes?

code P0341, also occasionally have trouble shifting out of park, have to use the override. Brake lights work, so I don't know if it is the brake switch, but I will be replacing that tonight just in case. Taking it in to Acura tomorrow morning.

Symptoms

The car will likely run with this code set, as it is often intermittent and also because the PCM can often operate the vehicle in "limp-in/limp-home" mode even with a cam sensor signal problem. There may be no noticeable symptoms other than:

Poor fuel economy (if engine runs)
Possible no start condition
Causes

A code P0341 may mean that one or more of the following has happened:

Cam sensor wiring routed too close to spark plug wiring (causing interference)
Poor wiring connection at cam sensor
Poor wiring connection at PCM
Bad cam sensor
Damaged reluctor wheel
Possible Solutions

Often relacing the sensor fixes this code, but not necessarily. Therefore it's important to check the following:

Check that the wiring isn't routed too close to any secondary ignition components (coil, spark plug wires, etc.)
Visually inspect the wiring at the sensor for any burn marks, discoloration indicative of melting or chafing
Visually inspect the cam sensor for damage
Visually inspect the reluctor wheel through the cam sensor port (if possible) for any missing teeth or any damage
If reluctor isn't visible from outside the engine, visual test can only be done by removing cam shaft or intake manifold (depending on engine design)
If all checks out okay, then replace the sensor.
