Sensor Operating Specifications

1994 Plymouth Laser RS Turbo, AWD, AutomaticSECTION Sensor Operating Specifications
NOTE: Unless stated otherwise in test procedure, perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance.
AIRFLOW SENSOR RESISTANCE(1)

Application Terminals No. Ohms
1.8L & 2.0L Non-Turbo 4 & 6 (2) *
2.0L Turbo 6 & 8 (2) *
(1) For testing procedure, see SYSTEM/COMPONENT TESTS article in this section.
(2) Resistance should be approximately 6000 ohms at 32°F (0°C), 2700 ohms at 68°F (20°C) and 400 ohms at 176°F (80°C).

OXYGEN SENSOR VOLTAGE(1)

Application Volts
1.8L (2) .6-1.0
2.0L (3) *
(1) For testing procedure, see SYSTEM/COMPONENT TESTS article in this section.
(2) Warm engine until coolant temperature reaches 176-194°F (80-90°C). Measure voltage with engine running at more than 1300 RPM.
(3) For sensor voltage range and testing procedure, see SYSTEM/COMPONENT TESTS article in this section.
THROTTLE POSITION SENSOR RESISTANCE(1)

Terminals No. Ohms
1 & 4 3500-6500
2 & 4 3500-6500
(1) Operate throttle valve slowly from idle position to full open position. Check if resistance changes smoothly in proportion to throttle valve opening angle.
VEHICLE SPEED SENSOR RESISTANCE(1)

Application Ohms
All Models (2) *
(1) For testing, see SYSTEM/COMPONENT TESTS article in this section.
(2) Connect ohmmeter across reed switch terminals, and rotate speedometer cable. Ohmmeter reading should fluctuate between continuity and no continuity.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • You smell fuel, burning insulation, or see smoke.
  • Brakes feel soft, pull hard to one side, or make grinding noises.
  • The engine overheats, stalls repeatedly, or misfires under load.
  • You are missing required tools, torque specs, or safe lifting equipment.
  • You are not confident in the next step or safety outcome.
