Product Information

When a code P011B is stored in an OBD-II vehicle, it means that the powertrain control module (PCM) has detected a problem with the correlating signals between the engine coolant temperature (ECT) sensor and the intake air temperature (IAT) sensor. First, let’s clear up the confusion about the different names given to the various travel expense allowances offered by HMRC. The per diem system is usually used to cover subsistence expenses, i.e. expenses related to work-related travel, or time that an employee has to spend away from their normal workplace while working.

The ECT sensor provides data to the PCM, for drivability strategy and electronic cooling fan operation. It may also serve to provide a signal to the temperature gauge in the instrument cluster. But HMRC outlines some additional criteria that have to be met to qualify for the meal allowance on business travel: If you do need to replace the MAF sensor, we recommend using an original equipment OEM one from the manufacturer rather than buying an aftermarket part.Increasing engine coolant temperature causes the level of resistance in the ECT resistor to decrease and circuit voltage to increase. The PCM recognizes these variations in ECT voltage as changes in engine coolant temperature. A diagnostic scanner, a digital volt/ohmmeter (DVOM), and a reliable vehicle information source are among the tools that will be required to diagnose a code P011B. If all ECT/IAT sensors and circuits are within specifications, suspect PCM failure or a PCM programing error. The IAT sensor acts in much the same manner as the ECT sensor, except with a much narrower range. It only monitors variations in ambient air as opposed to changes in engine cooling temperature. The IAT sensor is typically positioned so that ambient intake air may be drawn across it as it is enters the engine intake. The IAT sensor is almost always inserted into the air filter housing or air inlet pipe. This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles (Nissan, Chevrolet, GMC, VW, Toyota, Mazda, Ford, Audi, Honda, etc.). Although generic, the specific repair steps may vary depending on make/model.

If the PCM detects voltage signals from the ECT sensor and the IAT sensor which differ by more than a preprogrammed degree, a code P011B will be stored and a malfunction indicator lamp (MIL) may be illuminated. Multiple ignition cycles, with a failure, will be required for MIL illumination on some vehicles. What is the severity of this code? The exact amount a business can give to their employee for meal expenses varies depending on these two different factors.Visually inspect all MAF sensor wiring and connectors to make sure they are intact, not frayed, broken, routed too close to ignition wires/coils, relays, motors, etc. Test individual system circuits using the DVOM if all ECT/IAT sensors comply with manufacturer’s specifications. is not within a predetermined expected range of the calculated MAF value. Refer to a make/model specific repair manaul to determine which is the "B" circuit for your vehicle. Note: Some MAF sensors also incorporate an air temperature sensor, which is another value used by the PCM for optimal engine operation.
