Checking my data base show no P-0173 code for the 2002 Sebring Coupe with the 3.0L engine (Mistubushi Built Vehicle). The Chrysler Manual shows P0171 System too lean (bank 1), P0172 System too rich (bank 1), P0174 System too lean (bank 2), P0175 System too rich (bank 2). In any case, Fuel Trim Rich or Lean, Here are some TROUBLESHOOTING HINTS (The most likely causes for this code to be set are: ) • Volume air flow sensor failed. • Injector failed. • Incorrect fuel pressure. • Air drawn in from gaps in gasket, seals, etc. • Bank 1or 2 heated oxygen sensor failed. • Engine coolant temperature sensor failed. • Intake air temperature sensor failed. • Barometric pressure sensor failed. • Use of incorrect or contaminated fuel. • ECU failed. <M/T> • PCM failed. <A/T> Bank 1 indicates the right bank side cylinder, and bank 2 indicates the left bank side cylinder.
