DTC P0016 (LPL or LPV)
Diagnostic Instructions
DTC Descriptor
DTC P0016 00: Crankshaft Position - Intake
Camshaft Position Not Plausible |
Circuit/System Description
The camshaft position sensor correlates the crankshaft to
camshaft position so that the engine control module (ECM) can
determine which cylinder is ready to be fueled by an injector. As
the camshaft rotates, the reluctor wheel interrupts a magnetic
field produced by a magnet within the sensor and sends a signal to
the ECM through the signal circuit.
Conditions for Running the DTC
• |
DTCs P0335 and P0336 are not
set. |
• |
The engine speed is greater
than 50 RPM. |
• |
The DTC runs continuously once
the above conditions are met. |
Conditions for Setting the DTC
The ECM detects an incorrect camshaft position signal.
Action Taken When the DTC Sets
DTC P0016 is a Type C DTC.
Conditions for Clearing the DTC
DTC P0016 is a Type C DTC.
Diagnostic Aids
The following conditions can also set the DTC:
• |
Physical damage to the
camshaft position sensor or the reluctor wheel |
• |
Excessive play or looseness of
the camshaft position sensor or the reluctor wheel |
• |
Improper installation of the
camshaft position sensor or the reluctor wheel |
• |
Foreign material passing
between the camshaft position sensor and the reluctor wheel
|
• |
Excessive air gap between the
camshaft position sensor and the reluctor wheel |

Circuit/System Verification
1. |
Engine running, observe the
DTC information with a scan tool. DTC P0016 00 should not
set. |
2. |
Operate the vehicle within the
Conditions for Running the DTC to verify the DTC does not reset.
You may also operate the vehicle within the conditions that you
observed from the Freeze Frame/Failure Records data. |
Circuit/System Testing
1. |
Ignition OFF, disconnect the
harness connector at the B23 Camshaft Position Sensor. |
2. |
Test for less than 5 Ω
between the low reference circuit terminal 2 and ground.
|
⇒ |
If greater than the specified range, test the low
reference circuit for an open/high resistance. If the
circuit/connections test normal, replace the K20 Engine Control
Module. |
3. |
Ignition ON, test for 4.8-5.2
V between the 5 V reference circuit terminal 3 and ground.
|
⇒ |
If less than the specified range, test the 5 V
reference circuit for a short to ground or an open/high resistance.
If the circuit tests normal, replace the K20 Engine Control
Module. |
4. |
Ignition ON, test for 4.8-5.2
V between the signal circuit terminal 1 and ground. |
⇒ |
If less than the specified range, test the signal
circuit for a short to ground or an open/high resistance. If the
circuit tests normal, replace the K20 Engine Control Module. |
⇒ |
If greater than the specified range, test the
signal circuit for a short to voltage. If the circuit tests normal,
replace the K20 Engine Control Module. |
5. |
If all circuits test normal,
test or replace the B23 Camshaft Position Sensor. |
