Causes
- Faulty M/C pressure sensor (internal short or failed element)
- Open or shorted wiring in the sensor signal circuit (short to ground)
- Poor or corroded connector or terminal at the sensor
- Loss of reference or supply voltage from the ABS/ECU
- Faulty ABS/traction control module input circuitry
- Water intrusion or contamination at the sensor/connector
Symptoms
- ABS warning light and/or brake system lamp illuminated
- Traction/stability control warnings or disabled functions
- Diagnostic trouble code C1362 stored in ABS module
- Possible degraded or inconsistent braking/ABS behaviour
- No or very low signal reading for M/C pressure on scan tool
What to check
- Read and record freeze-frame and live data with a scan tool; verify sensor signal value
- Visually inspect sensor and connector for corrosion, damage, fluid contamination
- Check battery voltage and ground integrity at vehicle frame and at ABS module
- Check fuses and power feeds related to ABS/hydraulic control module
- Backprobe sensor connector: verify reference voltage, ground, and signal with ignition ON
- Perform wiggle test on wiring while watching live data for intermittent changes
Signal parameters
- Reference/supply voltage (typical): ~5.0 V with ignition ON (vehicle-specific)
- Sensor signal (typical): proportional to pressure, roughly 0.5–4.5 V across range
- Low-voltage fault threshold: sensor signal near 0.0–0.3 V (below expected idle value)
- Ground: near 0 V; check for high resistance causing erroneous readings
Diagnostic algorithm
- Use a scan tool to confirm C1362 is current or stored and capture live M/C pressure sensor data and freeze frame.
- Visually inspect sensor, harness and connector for physical damage, corrosion or fluid ingress. Repair any obvious issues.
- Verify battery voltage and good chassis and module grounds. Repair poor ground or low battery voltage before continuing.
- Locate sensor connector. With ignition ON (engine off), backprobe connector and measure: reference voltage, sensor signal, and ground. Compare to expected values.
- If reference voltage is missing or low, trace back to ABS/hydraulic module and fuses; repair power supply or module ground as required.
- If reference is present but signal is very low (near 0 V), inspect wiring for short to ground. Disconnect sensor and measure continuity between signal pin and chassis ground to confirm short.
- If wiring is intact and no short, replace the M/C pressure sensor and retest.
- If sensor replacement does not clear fault and wiring checks good, consider ABS/hydraulic control module input failure; consult manufacturer procedures for module testing/replacement.
- After repairs, clear codes, perform functional test/road test and recheck for code recurrence.
Likely causes
- Damaged/shorted signal wire to ground
- Corroded/loose sensor connector
- Failed pressure sensor
- Blown fuse or poor battery/ground causing low supply to sensor
- Faulty ABS/hydraulic control unit input
Fault status
Status
