Ford Mustang (1999-2004) Service Manual: Electronic Engine Controls - Cobra
Most of the Cobra engine electronic controls are similar to that of the non-supercharged 4.6L (2V) engine. These components are as follows:
- Crankshaft position (CKP) sensor
- Throttle position (TP) sensor
- Idle air control (IAC) valve
- Mass air flow (MAF) sensor
- Heated oxygen sensors (HO2S)
- Engine coolant temperature (ECT) sensor
There are also three controls that are unique to the Cobra engine. These are as follows:
- Integrated temperature and manifold absolute pressure (T-MAP) sensor
- Supercharger bypass vacuum solenoid
- Supercharger bypass vacuum solenoid - actuator
Supercharger Bypass Vacuum Solenoid and Actuator
The Supercharger bypass vacuum solenoid will bleed off boost under the following conditions:
- heavy engine misfire
- engine coolant over-temperature
- loss of intercooler fluid
- pump failure
This prevents damage that can occur if boost were allowed under these conditions. The solenoid is located on the upper LH side of the engine. The solenoid uses engine vacuum to operate a actuator and linkage that connects to the pressure bleed off valve. The actuator is located near the solenoid and is connected to it by a vacuum line.
Integrated Temperature and Manifold Absolute Pressure (TMAP) Sensor
The TMAP sensor is located on the upper LH side of the engine and is used to measure current manifold absolute pressure and manifold air charge temperature.
