What happens when DTC 16 53 and 57 are set?
When DTC 16 is set, the PCM will turn “ON” the engine cooling fan. If DTC 16, 53 and 57 are set, check for short to voltage on “Diagnostic Test” line. circuit 451. The PCM uses two different internal pull-up resistors to increase resolution throughout the entire range of engine operating temperatures.
What causes DTC 13 to be set too long?
An open circuit, defective, or contaminated sensor could cause the voltage to stay within a 410-477 millivolt band too long, keeping the system in open-loop and setting a DTC 13. Engine has been running for at least 4 minutes and 10 seconds, and…
What is the diagnostic trouble code for vs V6?
At normal engine operating temperature (85 degrees C to 95 degrees C), the voltage will measure about 2.2 to 1.8 volts. A Diagnostic Trouble Code 14 may enable TCC operation when cold. Test Description: Number (s) below refer to step number (s) on the diagnostic chart.
What is the diagnostic code for an engine misfire?
When the check engine light illuminates, your car’s primary computer, which is often referred to as the powertrain control module (PCM), will store a diagnostic trouble code (DTC) in its memory. Codes P0300 to P0312 are the primary DTCs associated with an engine misfire.
What causes a DTC code on a VCT?
Possible Causes: Open or short in the VCT circuit Open VPWR circuit Open or short in the VCT solenoid valve Diagnostic Aids: This DTC is a circuit check.

When do you clear a diagnostic trouble code?
Diagnostic trouble codes (DTCs) are normally the main goal of scanning, however, DTCs are often misunderstood. There is a misconception in the collision repair industry that when the physical repairs are completed, you hook up a scan tool, and clear all codes.
Why do I have a DTC on my car?
These DTCs were most likely set due to the vehicle being started and moved while the parts were disconnected. These codes should be cleared and verified they are corrected. This is a digital fingerprint of the repair process and may confuse future diagnostics if left in the system.
What causes a camshaft to fail a DTC Test?
The test fails when the camshaft timing exceeds a maximum calibrated value or remains in an advanced position. Possible Causes: Camshaft timing improperly set Continuous oil flow to the VCT piston chamber VCT solenoid valve stuck open Camshaft advance mechanism binding (VCT unit) Diagnostic Aids: This DTC is a functional check of the VCT unit.
