P0015 Ferrari 512 Diagnostic Trouble Code
P0015 Ferrari 512 code definition:
P0015 is a kind of OBD-II Diagnostic P-Powertrain Diagnostic Trouble Code for Ferrari 512.
P0015 Ferrari 512 is defined as Camshaft Position Sensor A Circuit Low. This means the CMP (camshaft position) sensor circuit on engine bank 1 sends an irregular reading. This is because the barometric pressure sensor is part of the MAF sensor. Sometimes, the MAF's sensing wire can accumulate and get covered with dirt, dust and/or oil residue, which can also lead to the error code.
Symptoms
Symptoms of a P0015 Ferrari 512 diagnostic trouble code may include:
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly
- Faulty or damaged wiring
- Hesitation upon acceleration
- The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.
|
Possible Causes :
- An air leak forward of the DPF will change the sensor readings resulting in the code
- Rusty exhaust systems, cracked exhaust manifolds or damaged or missing gaskets or donuts will cause air leaks.
- Defective ECU strategies or components will prevent proper regeneration

Common Misdiagnoses
- TP Sensor Learn Not Complete Problem
- Low Coolant Circuit Problem
- Cruise Control System - Vehicle Accel Too High Problem
- TFP Valve Position Switch-Drive Without Drive Ratio Problem
- Problem
Repair Processes :
It should be pretty close to battery voltage (12 volts). If not, then this is the circuit that has the problem.
Look for missing ground strap or a rusty ground where the fuel tank is grounded to the frame. Check for damage to the wiring harness connector.
