Detect Early Automotive Sensor Failures

Cost Savings

Checklist Tasks

• Watch for erratic idle or stalling after cold starts indicating airflow sensor issues.
• Check for sudden fuel efficiency drops to reveal oxygen or MAP sensor faults.
• Observe cruise control disengagement, possibly from throttle sensor failure.
• Note delayed or harsh transmission shifts for speed or temperature sensor errors.
• Inspect for intermittent ABS or traction lights to catch wheel speed sensor faults.
• Listen for engine pinging under load which may indicate faulty knock sensor.
• Test for slow or unresponsive acceleration for throttle or pedal sensor issues.
• Check if the check engine light stays on after refueling for gas cap or emissions sensor faults.
• Watch headlights/dash lights flicker with engine speed, indicating voltage sensor issues.
• Feel for rough shifting or limp mode activation signaling transmission sensor failure.
• Smell strong fuel odor at startup to detect failed coolant temperature sensor.
• Scan for diagnostic trouble codes even without warning lights to find hidden sensor issues.
