We replaced the crankshaft position sensor after the check engine light came on and the diagnostic test confirmed it was the crankshaft. After replacing, we tried to start it but it wont. Help

Good morning,

What was the code?

You need spark, fuel and compression to run. Was all this checked as well?

P0016 was the code, and yes, we checked everything.

Okay, the 16 code is not for the crank sensor. It is a correlation code between the cam and crank sensor. What this means is the timing may be out between the cam and crank.

The front cover should be removed and timing marks verified to be accurate.

I would start there.

General Description

The CVVT (Continuously Variable Valve Timing) system is installed to the chain sprocket of the camshafts. This system controls the camshaft to provide optimal valve timing. The PCM controls the Oil Control Valve (OCV), based on the signals output from air flow, throttle position and engine coolant temperature. The CVVT controller regulates the camshaft angle using oil pressure through the OCV. As result, the relative position between the camshaft and the crankshaft becomes optimal, and the engine torque improves, fuel economy improves, exhaust emissions decrease under overall driving conditions.

DTC Description

DTC P0016 is set when the actual camshaft position is retarded beyond the reference value. This condition may be caused by incorrect mechanical timing.

Signal Waveform & Data

1. Connect GDS and select Data Analysis.
2. After warming-up, check following items.

3. Data analysis
> A Sector : CVVT works
> B Sector : Limp Home Mode (CVVT doesn't work.)
> CVVT Control Flow (A Sector)
: Acceleration pedal (1) shift -> Engine RPM change -> Camshaft Position Setpoint (2) change -> CVVT Valve Duty (3) change -> Inlet CAM Position (4) change

The automotive place that diagnosed the problem going by what their scanner said, that it could be P0335.

Okay, where did the 16 code you gave me come from?

If they went by the code number, very rarely does a code identify a failed part, just a failed system. Diagnostics need to be done to verify the failure before throwing any parts to it.

I posted below a description and flow chart for you.

P0335 Crankshaft Position Sensor 'A' Circuit

Inspection/Repair - Component Inspection

Component Inspection

1. Set up an oscilloscope as follows :
(1)Channel A (+): Signal terminal of the CMPS #1 (back probe), (-): ground
(2)Channel B (+): Signal terminal of the CKPS (back probe), (-): ground
2. Start the engine and check for signal waveform compared with reference waveform as below.

ImageOpen In New TabZoom/Print

1 There are 60 signals of CKPS (Including missing tooth) during the semi-cycle of CMPS #1.
2 There are 3 - 5 signals of CKPS between the switching point of CMPS #1 and the missing tooth of CKPS.

3. Is the signal waveform normal?

The code is actually p0335. It came from the oil and lubes place that I get my cars oil change. The check engine light had been on that morning, and when I went to their shop, the hooked up their diagnostic reader to my car and that's the number it said plus crankshaft position sensor. Sorry about that first number. I should have checked with them first. Is it true that my car may be reluctant to start because we had the battery off for several days? Do I need to use my key fob to re program it?

The key may have forgotten the password for the security system. You may need the key reprogrammed.
