This DTC is output when the instrument cluster detects the fuel sender gauge malfunction.
This diagnostic procedure supports the following DTC:
DTC B1500 Fuel Sender Open Detected
The engine is running.
| • | When 10 seconds have elapsed since the engine started and IG voltage is 10.5 volts or more. | 
| • | A fuel sender gauge operation malfunction. | 
| • | The malfunction indicator lamp (MIL) illuminates the first time the diagnostic runs with the fault active. | 
| • | The fuel gauge does not operate. | 
The DTC will clear when conditions for setting the DTC have been repaired.

1  | Did you perform the Diagnostic System Check - Vehicle?  | --  | Go to Step 2  | |
2  | 
 Is the resistance measured within specified value?  | 13.5 - 414.5 Ohms  | Go to Step 9  | Go to Step 3  | 
3  | 
 Is the resistance measured within specified value?  | Between E1 terminal 25 and Q14 terminal 2 = Below 1 Ohm Between Q14 terminal 2 and body ground = 10 Kohms or higher Between Q14 terminal 3 and P10 terminal 1 = Below 1 Ohm Between P10 terminal 1 and body ground = 10 Kohms or higher Between P10 terminal 2 and E1 terminal 10 = Below 1 Ohm Between E1 terminal 10 and body ground = 10 Kohms or higher  | Go to Step 4  | Go to Step 8  | 
4  | 
 Are the resistance values within the specified values?  | Between upper side terminal 2 and under side terminal 2 = Below 1 Ohm Between upper side terminal 3 and under side terminal 3 = Below 1 Ohm  | Go to Step 5  | Go to Step 10  | 
5  | Is vehicle FWD?  | --  | Go to Step 6  | Go to Step 7  | 
6  | Inspect fuel sender gauge assembly as follows: 
 Is the resistance measured within specified value?  | Float level is upper = 13.5 - 16.5 Ohms Float level is between upper and lower = 13.5 - 414.5 Ohms (gradually changes) Float level is lower = 405.5 - 414.5 Ohms  | Go to Step 9  | Go to Step 11  | 
7  | Inspect fuel sender gauge assembly (main) and (sub) as follows: 
 Is the resistance measured within specified value?  | For Main: Float level is upper = 6.5 - 8.5 Ohms Float level is between upper and lower = 6.5 - 245.7 Ohms (gradually changes) Float level is lower = 240.7 - 247.7 Ohms For Sub: Float level is upper = 6.5 - 8.5 Ohms Float level is between upper and lower = 6.5 - 168.8 Ohms (gradually changes) Float level is lower = 164.8 - 168.8 Ohms  | Go to Step 9  | Go to Step 11  | 
8  | Repair or replace harness of the instrument cluster, fuel gauge assembly (main) or fuel gauge assembly (sub) connector. Refer to Wiring Repairs and Connector Repairs . Did you complete the repair or replacement?  | --  | Go to Step 12  | --  | 
9  | Replace the instrument cluster. Refer to Instrument Cluster Replacement . Did you complete the replacement?  | --  | Go to Step 12  | -- Go to Step 8  | 
10  | Replace the fuel suction pump and gauge. Refer to Fuel Pump and Fuel Filter Assembly Replacement for the 1.8 L engine or Fuel Pump and Fuel Filter Assembly Replacement for the 2.4 L engine. Did you complete the replacement?  | --  | Go to Step 12  | --  | 
11  | Replace the fuel sender gauge. Refer to Fuel Sender Assembly Replacement for the 1.8 L engine or Fuel Sender Assembly Replacement for the 2.4 L engine. Did you complete the replacement?  | --  | Go to Step 12  | --  | 
12  | 
 Does the DTC reset?  | --  | Go to Step 2  | System OK  |
