How to tell if a harmonic balancer needs replacing?
There is no fixed time for this but there are symptoms from which it can be inferred that the balancer needs a replacement. As time goes by, the harmonic balancer attached to the crankshaft can go bad due to continuous contact with chemicals, from other elements and/or from old age.
What do I need to know about the p0018 code?
When in doubt, remove the cam gear and the crankshaft harmonic balancer and inspect the tone rings. If the cam and cranks sensor check out OK, but you still have P0018 code illuminated, you’ll need to check the sensor circuit.
Where is the p0016 sensor located on a PCM?
Should the timing be off, the PCM will set a code P0016. This code stands for Crankshaft Position – Camshaft Position Correlation (Bank 1 Sensor A). Where is the P0016 sensor located?
What are symptoms of crankshaft pulley / harmonic balancer failure?
One of the crankshaft Pulley/harmonic Balancer failure symptoms is a very loud noise from the engine. When there is engine vibration, there will surely be a lot of loud noises coming from your engine. The noise will start to pop once you shift to a higher gear. If the noise becomes louder or is very loud, do not attempt to drive your car.
What does the trouble code p0012 stand for?
P0012 OBD-II Trouble Code: Camshaft Position A – Timing Over-Retarded (Bank 1) Here is what a P0012 means…
What causes the variable camshaft timing code p0012?
This over-retarded timing condition could be during the advancing or retarding phase of the camshaft timing. What causes the P0012 code? The variable camshaft timing (VCT) oil control valve (OCV) stuck in the open position.
What causes the ECM to trigger a p0012 fault?
Here are a few things which could cause the ECM to trigger a P0012 fault: Contaminate engine oil (rare fault). Inadequate oil flow to the variable camshaft timing (VCT) oil control valve (OCV). Defective VCT oil control valve (OCV). Control valve more than likely stuck in open position. Defective camshaft phaser.
Where is Bank 1 on a p0012 engine?
The “A” camshaft is either the intake, left, or front camshaft. This code is specific to bank 1. Bank 1 is the side of the engine that contains cylinder #1. Most likely a P0012 DTC will result in one of the following: There are potentially other symptoms as well.
