I have a 2001 Mustang and it's getting poor fuel milage and I've sall ready completed a major tune up and that did not help. I have ran a code check on it and found four codes they are P0113, P0118, P1298 AND P1509, I checked all the items out and they test good so I'm stumped can any one help?

P0113 Intake Air Temperature [IAT] Sensor Circuit High Voltage P0118 Engine Coolant Temperature [ECT] Sensor Circuit High Voltage P1298 Injector Driver Module Failure P1509 I need the engine code and the year code on the vin Most come up as IAC trouble All of these will cause poor fuel economy and performance, so they all can't be ckecking out OK! Temp sensor, have you replaced it? And does the car have a custom air intake? Thie intake plenum has 2 sensors on it the MAF and air temp sensor thats your 113 code, get back to me on the modification!

If the CCRM is not sending power to the driver mod, you'll need to replace it!
