Sensor limits – Engine control is dependent upon accurate readings from the MAP sensor. Beyond the limits of the stock MAP sensor (Approx. 4.84 volts) the ECU has no way to properly control the engine. Any turbocharger upgrade must also be accompanied by an appropriate MAP sensor. If the sensor limitations are met, the car can produce a fuel cut condition. The problem results from maxing out the Pre-throttle MAP sensors. When this occurs an alternate fuel state is entered and any load then produces a fuel cut. A data log will show this as injector pulse-width returning to a near idle value. If this issue is experienced, (CTO!) disabling DTC's P0241 and P0242 will remove the sensor checks allowing the engine to run outside of the sensors range. These DTC's should only be used as a diagnostic aid as this removes the ECU's ability to determine if a sensor is defective. If this test isolates the issue, appropriate MAP sensors should be selected for the vehicles targeted boost level.
