2008 V6 Mustang Limp Mode

[Jayp324]

I purchased a 2008 Mustang from a friend replaced the engine with an 09 engine. I replaced the timing chain and tuned the engine up. The issue i have now is when a cruising at 60-70 mph after about 15 minutes the car goes into limp mode. P061C, i have changed the crank shaft sensor, the cam shaft sensor and the throttle body. Do I need to replace the PCM?

Check battery voltage and voltage to the sensors. Did you do a relearn on the TB?

 

[Jayp324]

Yes,
The problems was happening before i changed the throttle body.

You should inspect all the wiring to those sensors for damage. A swapped engine can cause pinching or chafing of wires .

I have a 06 GT. I replaced the engine with a 2009 gt. I added the TB from the 09 but my car did NOT like it. So I returned the 06 GT TB and the car ran fine. Something to try. Also make sure you connected the exhaust manifold sensors to the right side. I had mine swapped and car ran funny.

The code it gives me is P061c….Any advice to fix this?

Much better limp mode

Have you tested the CPS wire? It should be high ohm against the engine housing (AFAIK). An other test could be a cooling spray at the ECU, when the car is in limp mode again, to see if it is heat related.

Can a key made by a locksmith cause PCM issues

 

[86GT351]

The P061C OBD error code in a Ford Mustang indicates that the Powertrain Control Module (PCM) has detected an issue with the engine's RPM monitoring system.

Possible causes

• A faulty Crankshaft Position Sensor (CKP)
• A faulty Camshaft Position Sensor (CMP)
• A poor electrical connection at the CKP or CMP circuit
• An open or shorted CKP or CMP harness
• A malfunctioning PCM

Thanks, I took it to the shop to have the PCP checked. I changed the sensors. I didn’t see any wiring issues.
