What Does P2032 Mean?
The EGT sensor circuit for Bank 1 Sensor 2 is reading abnormally low voltage, below the expected range. This indicates the sensor is reading temperatures lower than physically possible or has an electrical short to ground.
Common Causes
45%
EGT sensor internal short circuit or failure
30%
Wiring harness short to ground between sensor and PCM
15%
Damaged or corroded sensor connector creating ground path
7%
Sensor mounting issue causing poor thermal contact
3%
PCM internal fault on sensor circuit
Diagnostic Steps
1
Step 1: Disconnect EGT sensor and measure resistance - compare to temperature/resistance chart
2
Step 2: Check for short to ground in wiring harness with sensor disconnected
3
Step 3: Inspect sensor connector and terminals for moisture, corrosion, or damage
4
Step 4: Verify sensor signal voltage at PCM connector with sensor connected
5
Step 5: Test sensor with heat gun or propane torch to verify resistance change with temperature
Estimated Repair Cost
$150 - $400
Parts + labor, varies by vehicle and location
The EGT sensor circuit for Bank 1 Sensor 2 is reading abnormally low voltage, below the expected range. This indicates the sensor is reading temperatures lower than physically possible or has an electrical short to ground.
The most common cause of P2032 (Exhaust Gas Temperature Sensor Circuit Low Bank 1 Sensor 2) is: EGT sensor internal short circuit or failure
Typical repair costs for P2032 range from $150 to $400, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle can be driven cautiously but DPF regeneration may not function properly on diesel engines. Extended driving may cause engine derate or limp mode.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2032 to identify the root cause.
