Transfer Case Position Sensor Circuit Range/Performance
What does C0213 mean?
The C0213 code means the vehicle's onboard diagnostic system has detected: Transfer Case Position Sensor Circuit Range/Performance. This is a moderate severity code.
Common Symptoms
- 4WD indicator light flashing or incorrect
- Transfer case shifts erratically
- Cannot select specific 4WD mode
- Service 4WD warning
- Transfer case position unknown to module
Probable Causes (Ranked by Likelihood)
- Worn transfer case position sensor or encoder Very High
- Transfer case not fully engaging selected mode High
- Corroded position sensor connector Moderate
- Control module not receiving valid position data Low
Step-by-Step Diagnostic Procedure
-
Read transfer case position sensor data with scan tool
-
Check for proper engagement in each mode
-
Inspect position sensor connector for corrosion
-
Test position sensor resistance through range of positions
-
Attempt transfer case relearn or recalibration
Frequently Asked Questions
Can low transfer case fluid cause position sensor issues?
Low fluid can cause the internal components to not shift completely, making the position sensor read an in-between value. Always check transfer case fluid level and condition.
Is the position sensor inside or outside the transfer case?
The position sensor or encoder is typically mounted externally on the transfer case, often integrated with or near the shift motor assembly. It can usually be replaced without case disassembly.
What does range/performance mean?
A range or performance code means the sensor is producing a signal, but the values are outside the expected parameters or are erratic, rather than a complete loss of signal.
