What Does P2083 Mean?
The exhaust gas temperature sensor circuit on Bank 2 Sensor 1 is experiencing intermittent signal dropouts or erratic readings. The PCM is detecting sporadic loss of signal or sudden unexpected changes in sensor values.
Common Causes
35%
Corroded or loose sensor electrical connector with intermittent contact
30%
Damaged or chafed wiring harness causing intermittent opens or shorts
20%
Failing EGT sensor with intermittent internal resistance changes
10%
Vibration or heat-induced sensor mounting looseness causing intermittent connection
5%
PCM connector terminal corrosion affecting sensor circuit
Diagnostic Steps
1
Step 1: Perform thorough wiggle test on sensor connector and harness while monitoring sensor voltage on scan tool
2
Step 2: Inspect connector for heat damage, corrosion, or moisture intrusion; clean and apply dielectric grease
3
Step 3: Check harness routing for contact points with hot exhaust components or sharp edges causing abrasion
4
Step 4: Monitor sensor signal stability during engine temperature cycling from cold to hot operating temperature
5
Step 5: Test sensor resistance while applying mechanical stress (light tapping) to identify internal intermittent failures
Estimated Repair Cost
$120 - $550
Parts + labor, varies by vehicle and location
The exhaust gas temperature sensor circuit on Bank 2 Sensor 1 is experiencing intermittent signal dropouts or erratic readings. The PCM is detecting sporadic loss of signal or sudden unexpected changes in sensor values.
The most common cause of P2083 (Exhaust Gas Temperature Sensor Circuit Intermittent Bank 2 Sensor 1) is: Corroded or loose sensor electrical connector with intermittent contact
Typical repair costs for P2083 range from $120 to $550, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive but intermittent sensor failures may prevent proper DPF regeneration cycles. Prolonged operation may result in DPF clogging and expensive repairs.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2083 to identify the root cause.
