P247C is the bank 2 counterpart of P2478: the first exhaust probe on the second cylinder bank reports a temperature outside its permitted window, typically next to the turbine outlet or catalyst inlet of that bank. It needs a V engine with separate exhaust paths and its own probe per bank. No maker documents P247C in public material; Ford's 2015 diesels with their single exhaust stream use only the bank 1 numbers, with a high-side limit of about 1150 °C, and Volkswagen's 2014 2.0L TDI checks the target-to-actual gap. Comparing both banks helps: if only bank 2 runs hot, look at that bank's injectors, turbo and air supply before replacing the probe.

Likely causes

Bank 2 running hot from extra fuel or a faulty injector

Bank 2 probe 1 reading too high

Air shortage on bank 2 from a boost leak or turbo fault

Symptoms

MIL on
Reduced power to protect the exhaust
Bank 2 probe reads clearly above bank 1
