Question about 2001 Chrysler PT Cruiser

1 Answer

Sputtering/ chugging while driving

The car had been sitting for a while, not running right, so I changed the spark plugs and checked the camshaft positioning sensor but when I removed it I lost one of the bolts... Haven't had a chance to replace it yet, but when I started driving it, the car ran PERFECT!! However, after about 15 miles started chugging and sputtering pretty bad.... Parked the car for about 2 weeks and tried running it again, same thing, running really rough... Actually in park or neutral its really smooth, but when driving its rough. I unplugged the battery to reset the computer, and after about 15 minutes hooked it back up. RAN GREAT!!!....... for about 15 miles, then same thing... Any ideas??

Disconnecting the battery could reset codes and/or sensor readings in the engine computer.
Is the check engine light on, and have you checked the computer for trouble codes ? Is fuel pressure normal ?

Posted on Aug 27, 2015

Testimonial: "Fuel pressure is normal, no check engine code... I really think its the sensor not reading properly as it is not connected with both bolts, and I believe it also applies pressure to the crankshaft, so I HOPE this is the problem and an easy fix!"

Your problem sounds like it may be a Mass Air Flow sensor, when it does run bad disconnect the sensor, if the engine starts running ok the sensor is bad, this would be the most common reason for your problem and why it is only intermittent. As far as the overheat do you have a coolant leak?

SOURCE: 2 spark plugs not firing

check to see if your plugs need changing and then check your HT/LT leads on the plugs as they may be loose or water clogged somewhere or have a split wire that is just touching enabling it to fire a few times

Yes, and I believe you know that.

Why would drive around, without replacing a battery,you had tested,and came up bad?
Then go on the internet, to tell your story ?

2000 trail blazier with random misfire,sulfur smell, glowing convertor. New cap,rotor button plugs,plug wires and convertor NO CHANGE ! ANY IDEAS ?


Is the check engine light lit ? Any DTC'S - diagnostic trouble codes ? What engine ? 4.3 L vortex . Leaking fuel pressure regulator under the upper intake manifold . Leaking fuel injectors ! Ignition timing problem . How does the engine run ? Who installed the plugs an wires ? are they right ? Fuel pressure leak down test, fuel injector balance testing . Check distributor drive gear an slop in the shaft . Did you have distributor out ? Is it in the proper position ? What cylinder is misfiring ? engine mechanical problem ! What do spark plugs look like ? fouled , soaked with fuel . Do a engine compression test .
The camshaft drives the distributor shaft which rotates providing a spark to the correct cylinder by way of the cap and rotor. The camshaft position sensor functions much like the crankshaft sensor previously described but provides only a 1x signal to the VCM. That is, for every 2 rotations of the crankshaft, there is 1 rotation of the camshaft. Note that the CMP sensor will not affect driveability. The sole purpose of the CMP sensor is to provide the VCM with the necessary information for the misfire DTCs.

Crank position sensor


Check if you have spark on a plug wire when it is cranking over and wont start. If you have no spark, a good guess is the crank position sensor. Often the cause of no spark, but could also be the ignition control module, the camshaft position sensor, or the pcm. If you want to be sure before replacing the sensor, have the sensor tested while on the car. A shop could test it.

Do you have to remove the cam gear to change the camshaft senaor.


Courtesy of a Beetle forum.

The camshaft position sensor is located at the front of the cylinder head under the timing belt cover. On 2.0L models, the camshaft position sensor is located behind the camshaft sprocket and is equipped with a pigtail lead and a remote connector. On 1.8L turbo models, the camshaft position sensor is located at the front of the intake camshaft. check the terminals in the connector and the wires leading to the sensor for looseness and breaks. Repair as required.

Before checking the camshaft position sensor, check the voltage supply and ground circuits from the ECM. Dosconnect the electrical connector from the camshaft position sensor and connect a voltmeter to terminals 1 and 3 at the harness connector from the camshaft position sensor and connect a voltmeter to terminals 1 and 3 at the harness connector. Turn the ignition key On - the voltage should read approximately 5.0 volts. If the voltage is incorrect, check the wiring from the camshaft position sensor to the ECM. If the circuits are good, have the ECM checked at a dealer service department or other properly equipped repair facility.

To check the camshaft position sensor operation, reconnect hte connector to the camshaft position sensor and using a suitable probe, backprobe terminal no. 2 of the camshaft position sensor connector. Connect the positive lead of a voltmeter to the probe and the negative lead to a good engine ground point. Turn the ignition key On. Rotate the engine slowly with a breaker bar and socket attached to the crankshaft pulley center bolt while watching the meter. The voltage should fluctuate between zero volts and 10.0 volts as the vanes in the reluctor wheel past the sensor. If the test results are incorrect, replace the camshaft position sensor. Note: Rotate the engine slowly through at least two complete revolutions. Removing the spark plugs from the engine will make the crankshaft much easier to turn. Warning: If you remove the spark plugs, unplug the primary (low voltage) electrical connector(s) from the ignition coil(s) to disable the ignition system

1. Remove the ignition coils (lines at end this document), then return here once you have gotten the Coil
Packs off and precede with step 2 from here.
2. Clean the spark plug recesses with low pressure air. CAUTION: Wear safety glasses
when using compressed air, as flying dirt particles may cause eye injury. NOTE:
Clean the spark plug recess area before removing the spark plug. Failure to do so could
result in engine damage because of dirt or foreign material entering the cylinder head, or
by the contamination of the cylinder head threads. The contaminated threads may prevent
the proper seating of the new plug. Use a thread chaser to clean the threads of any
contamination.
3. Remove the spark plugs from the cylinder head. NOTE: Allow the engine to cool before
removing the spark plugs. Attempting to remove the spark plugs from a hot engine may
cause the plug threads to seize, causing damage to cylinder head threads.
4. Inspect the spark plugs.

INSTALLATION PROCEDURE

1_23_2012_5_11_30_pm.jpg

1. Measure the spark plug gap on the spark plugs to be installed. Compare the measurement
to the gap specifications. NOTE:
• Use only the spark plugs specified for use in the vehicle. Do not install spark
plugs that are either hotter or colder than those specified for the vehicle. Installing
spark plugs of another type can severely damage the engine.
• Check the gap of all new and reconditioned spark plugs before installation. The
pre-set gaps may have changed during handling. Use a round feeler gage to ensure
an accurate check. Installing the spark plugs with the wrong gap can cause poor
engine performance and may even damage the engine.
2. Install the spark plugs to the cylinder head. NOTE:
• Be sure that the spark plug threads smoothly into the cylinder head and the spark
plug is fully seated. Use a thread chaser, if necessary, to clean threads in the
cylinder head. Cross-threading or failing to fully seat the spark plug can cause
overheating of the plug, exhaust blow-by, or thread damage.
• Refer to Component Fastener Tightening Notice in Service Precautions.
Tighten the spark plugs to 18 N.m (13 lb ft).

1993 ford taurus, replaced all starting and charging componets still no spark to plugs. Checked all fuses and all fusible links. Replaced key switch, ignition switch,neutral safty...


The camshaft position sensor sends a signal to the PCM, powertrain control module. The PCM then determines spark plug firing. Could be the camshaft position sensor.

1996 is all I have
Camshaft Position (CMP) Sensor 3.0L (2V) Engine
The camshaft position sensor (CMP sensor) (12126):
  • is a single Hall-effect magnetic switch activated by a single vane which is driven by the camshaft (6250).
  • provides camshaft position information which is used by the ignition coil (12029) and the powertrain control module (PCM) (12A650) for fuel synchronization.
3.0L (4V) Engine
The camshaft position sensor (CMP sensor) (6B288) is:
  • a variable reluctance sensor.
  • triggered by the high-point mark on the LH exhaust camshaft sprocket (6256).
-----------------
