Causes
- Failed crankcase pressure (PCV) sensor
- Open, shorted or corroded wiring/connectors between sensor and control module
- Poor sensor power or ground
- Faulty or misconfigured control module (ECM/PCM/BCM) expecting the data
- CAN/LIN bus faults, broken termination, or interference from aftermarket devices
- Intermittent connection (water ingress, vibration), or software/firmware bug
Symptoms
- Malfunction Indicator Lamp (MIL) or ABS/other module warning may be set
- Recorded DTC for crankcase pressure communication and possibly related U-codes
- Loss or invalid crankcase pressure data on a scan tool
- Possible rough idle, reduced engine performance or elevated crankcase pressure control symptoms (depends on vehicle control logic)
- Possible oil leaks or PCV-related drivability issues if control strategy relies on sensor
What to check
- Read all stored U/P codes and freeze-frame data with a capable scan tool; note occurrence and conditions
- Check for other network-related U-codes that indicate bus-wide problems
- Visually inspect sensor, wiring, and connectors for damage, corrosion, or contamination
- Check sensor supply voltage and ground at the connector with key ON (usually 5 V reference and ground)
- Measure signal output from the sensor (voltage or message presence) at key ON and during engine operation
- Confirm CAN/LIN bus health: measure CAN_H/CAN_L idle voltages (~2.5 V) and check for proper termination
Signal parameters
- Sensor types: may be analog (3-wire: reference, ground, signal) or smart sensor sending data over CAN/LIN
- Typical analog output range: ~0.5–4.5 V proportional to pressure (manufacturer-specific)
- Expected crankcase pressure magnitudes: small vacuum or slight pressure, typically near 0 mbar ± small range (vehicle-dependent)
- CAN bus idle voltages: CAN_H ≈ 2.5 V, CAN_L ≈ 2.5 V; differential ~0 V at rest, correct levels when active
- Message/update rate: commonly 1–10 Hz for pressure sensors on CAN/LIN; exact frequency is manufacturer-specific
Diagnostic algorithm
- Connect a professional scan tool and confirm U060E plus any related codes; record freeze-frame and live data.
- Verify the sensor reports data on the scan tool. If no data, check for power and ground at the sensor connector with key ON.
- If supply or ground is missing, inspect/repair power/ground circuit. Re-check after repair.
- If power and ground OK, probe the sensor signal output. For analog sensors check voltage varies with engine state; for bus sensors check for CAN/LIN messages using a diagnostic tool or scope.
- Inspect wiring harness for damage, shorts to battery or ground, and poor connector pins; repair any issues and retest.
- Perform a wiggle test of the harness and connectors while monitoring live data to find intermittent faults.
- If wiring and power are good but the sensor shows no or invalid output, replace the crankcase pressure sensor and clear codes.
- If replacement does not restore communication, trace CAN/LIN bus back to modules; check bus termination and scan for other modules not responding.
- Check for software updates or TSBs; reflash or program modules if required per manufacturer procedure.
- After repairs, clear codes and perform road/operational test to confirm fault does not return.
Likely causes
- Sensor electrical failure (most common)
- Damaged connector or wiring harness (pin corrosion, chafing, broken conductor)
- Loss of reference voltage or ground at the sensor
- Local network (CAN/LIN) communication fault or module not responding
- Intermittent fault caused by thermal/vibration conditions
Fault status
Status
Lost communication/no valid data from crankcase pressure sensor; sensor not responding or invalid message received.
Repair difficulty: Medium
Diagnostic time: 1.0-2.5 hours
