What Does P1460 Mean?
An electrical fault exists in the temperature sensor that monitors the heated catalyst heater power switch on Bank 2. This sensor prevents overheating of the catalyst heating element.
Common Causes
40%
Faulty catalyst heater temperature sensor Bank 2
30%
Damaged wiring or corroded connector at temperature sensor
20%
Failed heated catalyst power switch or control module
10%
Open or short circuit in sensor signal wire
Diagnostic Steps
1
Step 1: Measure resistance of catalyst heater temperature sensor Bank 2 and compare to specs
2
Step 2: Inspect sensor connector and wiring for damage, corrosion, or loose pins
3
Step 3: Test sensor signal voltage at control module during cold and warm conditions
4
Step 4: Verify power supply and ground circuits to catalyst heater system Bank 2
5
Step 5: Check catalyst heater control module operation and sensor reference voltage
Estimated Repair Cost
$200 - $700
Parts + labor, varies by vehicle and location
An electrical fault exists in the temperature sensor that monitors the heated catalyst heater power switch on Bank 2. This sensor prevents overheating of the catalyst heating element.
The most common cause of P1460 (Heated Catalyst Heater Power Switch Temperature Sensor Electrical (Bank 2)) is: Faulty catalyst heater temperature sensor Bank 2
Typical repair costs for P1460 range from $200 to $700, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive. Elevated cold-start emissions but no immediate safety concerns during normal operation.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1460 to identify the root cause.
