What is the p0016 sensor on a Chevy Impala?

What is the p0016 sensor on a Chevy Impala?

A lot of the harness leading to and from the Crank/Cam sensors is going to be exposed to hot exhaust and vibration. This is a great place to start diagnosing P0016 in your Chevy Impala. It’s quick and easy to do this before moving on to the sensors themselves.

What does the code p1516 mean on a Chevy?

P1516 CHEVROLET Meaning The Engine Control Module (ECM) is the control center for the Throttle Actuator Control (TAC) system. The ECMdetermines the drivers intent and then calculates the appropriate throttle response. The ECMachieves throttle positioning by providing a pulse width modulated voltage to the TAC motor.

What does the code p0016 mean on an engine?

P0016 refers to which camshaft position sensor is out of time with the Crankshaft. P0016 should be considered an important trouble code to diagnose and repair. The crank and cam sensors work in tandem to produce the ideal air/fuel ratio for your engine. When this timing is off, the engine will typically not run (or barely run)

What causes a faulty throttle actuator on a p1516 Chevy?

P1516 CHEVROLET Possible Causes Faulty Throttle Actuator Control (TAC) module Throttle Actuator Control (TAC) module harness is open or shorted Throttle Actuator Control (TAC) module circuit poor electrical connection Check Throttle Actuator Control (TAC) module connector for water Binding or bent throttle plate-failed throttle body

What does the p0011 DTC on an Impala mean?

That consists of a few different components but the P0011 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is above a set limit (over-advanced), the engine light will be illluminated and the code will be set. The “A” camshaft is either the intake, left, or front camshaft.

How does the camshaft position sensor work on an Impala?

Their is a bulliten on this code #PIP4331 and it has you taking the camshaft magnet/sensor off and checking the spool valve and makeing sure it is protuding/proud of its bore. “If the spool valve IS slightly sticking out of (proud) of the bore, then using your finger attempt to press it inwards and then release it.

What happens to the crank sensor on a GMC?

The crankshaft sensor on GMC vehicles is synced to the powertrain control module, or PCM. When the crank sensor is replaced, it must be resynced to the PCM. Without resyncing, the PCM cannot properly determine the position of the crankshaft.

Can a crank and cam sensor be replaced?

I replaced both the cam and crank sensor and car still will not start but if I unplug the crank sensor it starts up and runs like crap. I can not figure out what to do next. My car has 91000 miles. My car has an automatic transmission. You should check to see if your vehicle has jumped timing.

Why does my Chevy Impala engine not run?

The crank and cam sensors work in tandem to produce the ideal air/fuel ratio for your engine. When this timing is off, the engine will typically not run (or barely run) Here are the major symptoms of P0016 in the Impala: Here are the most common causes of P0016 in the Impala, as well as diagnostic advice, and resources to further explore.

What are the sensors on a Chevy Impala?

The 2002 Chevy Impala with a 3.4-liter engine has two crankshaft position sensors, crankshaft position sensor A and crankshaft position sensor B. Replacing the sensors is easy once you know where they are. Crankshaft Position Sensor A. Crankshaft position sensor A is the sensor on the part of the engine block facing the front of the vehicle.

Is there a camshaft position sensor on a 3.8L V6?

The camshaft position sensor, on your 3.8L V6 GM engine, is a three-wire Hall Effect Type sensor. So, for it to work, it’s gonna’ need an external power supply and a path to ground (for this power).

When to replace the crankshaft position sensor on a GM 3800?

If you have a vehicle with the GM 3800 Engine which stalls randomly and may not always restart, then you likely have a bad crankshaft position sensor. If your vehicle runs perfectly but the tachometer sometimes registers incorrectly then you should replace this sensor ASAP before it leaves you stranded somewhere.

Where is the crankshaft position sensor located on a car?

Crankshaft position sensor A is the sensor on the part of the engine block facing the front of the vehicle. This sensor is slightly above and toward the passenger’s side of the engine oil filter. Crankshaft position sensor B is attached to the block of the engine near the rear of the engine compartment.
