Question about 1999 Pontiac Grand Am GT

1 Answer

Missfire My 99 Grand Am SE 3.4L keeps misfiring and will not run properly, i have replaced to timing chain, crankshaft and cam shaft sensors, plugs, wires, coil packs, ignition modual and the PCM/ECM. After replacing all of them it starts really hard, I can get it started and to runns really rough. When i hit the gss while its running it seems like it levels off and stops misfiring but it may just be that when it speeds up its not as noticable. From starting it i keep on ruining the starter drive. Any Help??

Getting p0016 code


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.

Need help getting multiple misfire and camshaft sensor and crankshaft sensor


You are getting cam & crank sensor errors along with multiple misfires and you suspect the timing chain? Or PCM? You must have already done some other things to believe this, since either the cam or crank sensor malfunctioning can cause multiple misfires.

I have the code P1309 (misfire monitor unable)on my F-150, year 2000, 6cyl, 4.2l... i change the camshaft sensor and the light wont turn off then i sincronized it but the check engine light still wont turn...


This is a code for missfire monitor disabled due to a problem with the cam shaft position sensor or wiring; the first thing to do is verify that the cam shaft syncronizer has not been removed/repositioned from the correct setting if it has been moved it is out of time now and will have to be timed with a special tool. If it has not been moved at all I would suggest removing the cam sensor that mounts on the top and inspect the sensor and the syncronizer for damage... if not damage is noticed check the wiring at the plug for loose pins and broken wires, and, if they are fine replace the sensor.

Tests/Procedures:
1. The code P1309 usually sets because the CMP synchronizer is not installed properly, and is "out of time".

2. If the special tool for installing the synchronizer is not available, the synchronizer must be installed with the crankshaft at 26 degrees AFTER TDC on the #1 cylinder COMPRESSION stroke. To find 26 After Top Dead Center (ATDC), set the engine at TDC of #1 compression stroke, then watch the teeth on the Crankshaft Position (CKP) sensor tone ring on the front of the crankshaft. Turn the engine by hand until an additional two and a half teeth on the tone ring have passed the CKP sensor. This will be 25 degrees ATDC (you can estimate 1 more degree from there). Then install the synchronizer so that when it is bottomed out, the skinny vane that rotates through the sensor is centered in the sensor opening.

3. Once the synchronizer and CMP sensor are installed, the misfire profile will need to be relearned. To do this, verify that the fuel level is between 1/4 and 3/4 tank, then drive the vehicle, and do 3 or 4 decelerations from 65 MPH down to 40 MPH without touching the brake pedal.


Hope this helps and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer. Thank you for using FixYa.

1996 bonneville keeps missing what about MAP sensor ? MAS replaced Plugs replaced throotle posistion sensor also


have you isolated what cylinder is causing the misfire . You need to check the coils for proper spark at each plug. If you have spark then you will need to check each injector for proper fuel. you can do this by unplugging each injector one at a time to try to isolate which cylinder the missfire is on
or you can have your local parts store scan the car and tell you what code is stored . Most misfire with cause a service engine soon light to come on if the light is on then there is a code store .
