Auto repairs eh? Maybe you can help me out
Can a messed up sensor (speed in particular) make the whole engine go haywire? Because I've taken my car to multiple shops (2001 Toyota solara v6) and I've had some say a Bad speed sensor and other say a bad catalytic converter
I seen no common relation between the speed sensor an a converter, however if the converter is below threshold then its clogged and exhaust cant pass through the platinum core causing the car to hesitate or buck jerk, however your speed sensor is run off your wheels on the ABS system so that's electronic.
here is what you may find when your cats are bad...
P0420 ? Catalyst System Efficiency Below Threshold (4-Cylinder engine)
? Three-way catalytic converter malfunction
? Open or short in heated oxygen sensor circuit (bank 1, sensor 2)
? Heated oxygen sensor malfunction (bank 1, sensor 2)
? Open or short in heated oxygen sensor circuit (bank 1, sensor 1) or A/F sensor 2 circuit
P0420 ? Catalyst System Efficiency Below Threshold (V-6 engine)
? Three-way catalytic converter malfunction
? Open or short in heated oxygen sensor circuit
? Heated oxygen sensor malfunction
As for that speed sensor this is more than likely what code you have...
P0500 ? Vehicle Speed Sensor Malfunction
? Open or short in speed sensor circuit
? Vehicle speed sensor malfunction
? Instrument cluster malfunction
? PCM malfunction
