1996 Jaguar Vanden Plas P1185, P1186, P1188 Error Codes: Fuel Pump Temperature Sensor Issue and Solutions

Hello everyone, I own a 1996 Jaguar Vanden Plas and recently my check engine light has come on. After connecting the car to an OBD-II scanner, I received three diagnostic trouble codes: P1185 (FTS High - Fuel Pump Temperature Sensor High), P1186 (FTS Low - Fuel Pump Temperature Sensor Low), and P1188 (Calibration Memory Fault). These codes are likely related to the fuel pump temperature sensor, as they indicate inconsistent readings—high and low temperatures being reported by the same sensor. This inconsistency typically points to a faulty sensor or an issue with its circuitry. My question is: Should I simply replace the fuel pump temperature sensor? Is a full fuel pump replacement necessary? Or does this require specialized diagnostics only available at a Jaguar dealership? I’ve seen similar cases online, and while some users report fixing it by replacing the sensor, others suggest that calibration issues (like P1188) may need professional intervention. I’d appreciate any real-world advice or troubleshooting steps from experienced owners or mechanics. Thank you in advance for your help—any insights would be greatly appreciated! ~Mark
