What Does P2036 Mean?
The EGT sensor circuit for Bank 2 Sensor 2 is reading abnormally high voltage. This indicates an open circuit condition or sensor reading impossibly high temperatures.
Common Causes
40%
Bank 2 EGT sensor open circuit or complete failure
25%
Open circuit in Bank 2 sensor wiring harness
20%
Loose or disconnected Bank 2 sensor connector
12%
Corroded terminals creating high resistance in Bank 2 circuit
3%
PCM internal circuit failure on Bank 2 input
Diagnostic Steps
1
Step 1: Check Bank 2 sensor connector for proper connection and terminal retention
2
Step 2: Measure sensor resistance with DVOM at ambient temperature and verify in range
3
Step 3: Test for open circuits or excessive resistance in wiring to PCM
4
Step 4: Verify PCM reference voltage present at sensor connector (typically 5V)
5
Step 5: Heat sensor with propane torch and monitor signal voltage change at PCM
Estimated Repair Cost
$150 - $400
Parts + labor, varies by vehicle and location
The EGT sensor circuit for Bank 2 Sensor 2 is reading abnormally high voltage. This indicates an open circuit condition or sensor reading impossibly high temperatures.
The most common cause of P2036 (Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 2) is: Bank 2 EGT sensor open circuit or complete failure
Typical repair costs for P2036 range from $150 to $400, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive but Bank 2 emissions controls are impaired. Diesel engines may experience power reduction or regeneration failures if not addressed.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2036 to identify the root cause.
