What Does P2483 Mean?
The exhaust gas temperature sensor 5 on bank 1 is providing readings that are outside expected parameters based on engine operating conditions. The sensor may be functioning but reading temperatures that don't correlate with calculated values or other sensor inputs. This indicates a performance or rationality issue rather than an electrical fault.
Common Causes
35%
Degraded or aging EGT sensor providing inaccurate but functional readings
25%
Exhaust leak near sensor affecting temperature measurement
20%
Carbon buildup or contamination on sensor element
15%
High resistance in wiring causing voltage signal degradation
5%
Incorrect sensor installation or wrong sensor type installed
Diagnostic Steps
1
Step 1: Compare sensor 5 readings to other EGT sensors during cold start, idle, and under load conditions
2
Step 2: Perform calculated vs. actual temperature comparison using scanner bidirectional controls or forced regeneration
3
Step 3: Inspect exhaust system for leaks at sensor location and surrounding areas using smoke test if available
4
Step 4: Remove sensor and inspect element for carbon deposits, physical damage, or contamination
5
Step 5: Measure wiring resistance from sensor to PCM and verify it's within 5 ohms total
Estimated Repair Cost
$150 - $700

The most common cause of P2483 (Exhaust Gas Temperature Sensor Circuit Range/Performance Bank 1 Sensor 5) is: Degraded or aging EGT sensor providing inaccurate but functional readings
Typical repair costs for P2483 range from $150 to $700, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive for short periods, but inaccurate readings may prevent proper DPF regeneration. Could lead to DPF clogging or damage if ignored.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2483 to identify the root cause.
