94 Cadillac Deville SLS OBD1 code S061 Temporary fix the S061 code is the right front Ride Control Sensor. Was Getting 7.6 Volts DC input signal and nothing going from the sensor back to the computer. Tried using the fix using a 220 ohm resistor and diode, found on the web, NO Luck! There are 4 wires going into the sensor, Black, Green, Red, and Orange. The Black and Green are both Grounds, the Red is the 7.6VDC input and the Orange is the reference signal going back the computer. Using an adjustable voltage regulator ( LM317T ) ic set at 2.65VDC. The Vin is the RED Wire, Vout is the Orange Wire, the Ground is the Black and Green Wires tied together, NOTE these wires are NOT the vehicle ground !!! Using 10K ohm resistor to replace the variable resistor and the fixed resistor. The 10k resistor is connected from the Vout to between Adjust and Ground pins of the ic. Using a 0.1uf capacitor connected to the Vin ic pin then to the (-)side of the 1uf capacitor the (+) end of the 1uf capacitor is then connected to the Vout ic pin. The procedure was to disconnect the wire pig tail going to the sensor and then cut the wires off near the sensor leaving several inches of wire between the freed connector and cut wire. The small circuit was built on the bench and using a 9 volt DC battery to test and double check the circuit output. Then plugged in for a test drive. Make sure to insulate between ALL ic leads and seal the circuit extra well and be sure to make a rugged project. The LM317T has an operating range of 0*-125*C so the idea was to route the circuit up near the engine to try to stay within the operational range of the ic, several cable ties attached it to the fuel line and free of all moving parts. PARTS used ....................... 1) LM317T ic 1) 10K ohm resistor 1) 1uf capacitor 1) 0.1 uf capacitor Thinking this over the same type circuit could be used to check other sensors malfunctions by using the proper output voltage.
