Services Performed
- Inspected and found no codes, so i proceeded to change the blower speed over and over and was not able to replicate an issue. I unplugged both the resistor and the blower motor to check for any damage due to over amping causing the connectors to melt, but everything appeared to be okay. I removed the cabin air filter to see if it was restricting airflow and found that it is clean and not causing any issues. I cannot replicate the customers concern at this time.
- Hood stuck shut. Carefully, used plastic pry and towel to open hood. Inspected and found that the hood stops were turned all the way in, not allowing any upwards pressure on the hood while it was closed, and it was letting the hood sag below the fender making the body lines look off. I turned them out 6 turns each and now the hood open and closes every time, and now sits even with the fenders. While the hood was open i went ahead and lubed the hood latch assembly.
- Inspected and found 2 codes, a p018c-00 – Low pressure fuel pressure sensor circuit low, and a p0316-00 – for a misfire detected on the first 1000 revolutions. I removed the number 2 coil and plug and found that the spark plugs are worn and in need of replacement. Next i went to diagnose the P018c, i started by unplugging the sensor and verifying the 5v, ground, and reference circuits are good to the PCM. I next jumped the 5v wire to the reference line and watched the PID on my scan tool, and it maxed out the pressure, I then did the same with the ground wire and jumped it to the reference line and the pressure bottomed out to 0 indicating that the low pressure fuel pressure sensor has and internal fault and can be causing the engine to run rough. At this time id recommend replacement of all 4 spark plugs and coil boots, along with the low pressure fuel pressure sensor and retesting.
- Removed and replaced fuel pressure sensor. Cleared codes and tested.
- Replaced all spark plugs with new. Boots were not provided so I reused the hold ones. Connections seem to be ok. Started and now idling as it should test drove and did not have any misfires come up. I recommend a GDI service for injectors.
