Im just a bit confused since the computer had no code stored for PIP sensor, but the codes that worry me are  212 - Loss of IDM (Ignition Diagnostic Monitor) input to EEC or SPOUT circuit grounded113 - ACT Sensor Circuit Above Maximum Voltage of 4.6 volts (O), ACT circuit has intermittently failed above the maximum of 4.6 volts (M)556 - Fuel Pump circuit failure113 i can prolly fix, its maybe the sensor thats going bad and prolly needs changing, i did noticed that the connection was full of sludge so maybe cleaning that will fix it, now code 212 and 556 is were my problem could be, Fuel Pump circuit failure what is it exactly ? Is it like a relay not working properly or is the pump itself failing ? And code 212 i dont know what it is . If someone can help me with this please .</blockquote>
