Crankshaft Position - Camshaft Position Correlation
What does this mean? OBD Code P0016refers to
The crankshaft position sensor (CKP) and Camshaft position sensor (CMP) work in harmony to control the spark/fuel delivery and timing. They both consist of a reluctor, or tone, ring which passes over a magnetic sensor, which generates a voltage, indicating position. The crankshaft sensor is part of the primary ignition system and functions as the "trigger". It detects the position of the crankshaft relays that information on to the PCM or the ignition module (depending on the vehicle) to control spark timing. The Camshaft position sensor detects the position of the camshafts and relays the information to the PCM. The PCM uses the CMP signal to identify the beginning of the injector sequence. What ties these two shafts and their sensors together is the timing belt or chain. The cam and crank should be precisely timed together. If the PCM detects that the Crank and Cam signals are out of time by a specific number of degrees, this P0016 code will set.
Symptoms Possible sumptoms of OBD code P0016
Malfunction Indicator Lamp (MIL) illumination The engine may run but with reduced performance The engine may crank but not start The engine may exhibit a rattle near the harmonic balancer indicating the tone ring is damaged The engine may start and run, but poorly
Causes Possible causes of OBD code P0016
Timing chain stretched, or timing belt skipped a tooth due to wear Misalignment of timing belt/chain Tone ring on crankshaft slipped/broken Tone ring on camshaft slipped/broken Bad crank sensor Bad cam sensor Damaged wiring to crank/cam sensor Timing belt/chain tensioner damaged
Possible Solutions First, visually inspect the cam and crank sensors and their harnesses for damage. If you notice broken/frayed wires, repair and recheck. If you have access to a scope, check the cam and crank patterns. If a pattern is missing, suspect a bad sensor or a slipping tone ring. Remove the cam gear and the crankshaft harmonic balancer and inspect the tone rings for proper alignment and make sure they're not loose or damaged or that they haven't sheared the key that aligns them. If they are properly installed, replace the sensor. If the signal appears normal, then check the timing chain/belt for proper alignment. If it's misaligned, check for a damaged tensioner that may have allowed the chain/belt to slip a tooth or several teeth. Also check that the belt/chain isn't stretched. Repair and recheck.

Possible causes. The button, wiring from the button to the PCM, PCM, wiring from the PCM to the cruise control module, cruise control module. Which in your case , the cruise module is the throttle body module. Drive by wire. Have the codes read.

First you need a 12v lamp in a holder or get someone to solder two wires to one, next disconnect the earth lead of the battery and connect the lamp between the battery and earth if you have battery drain the lamp will glow brit the less drain the less the lamp will glow, remember you will always have a bit of drain, now you can remove a fuse at a time and look at the lamp if it glows less this could be the circuit that's at fault. Good luck.
