Question about 1996 Chevrolet Blazer

1 Answer

Need to replace a cam sensor

My 96 S-10 blazer marks a hard knock sound when the speed approaches 55 mph. The service engine light came on and I had it put on a computer at the local auto parts store. The computer said I should replace the cam sensor. Small part, not expensive. Where can I find the bad part and replace it with the new?
Help and thanks in advance.

check the #3 O2 senser that is located just in front of the cat. really check the wiring that it connects to in that area, as mine had a wire pinched between the frame and the body ( from the factory) that eventaulaly wore through and casued the sensor to fail. usually no error code was set and the engine would stumble terrible from 40 to 60 mph. Had to replace the sensor with new, and clean out corrosion IN THE CONNECTER before everything was resolved.
there are 4 O2 sensors in the 97, 1 on each bank, 1 just before the cat and 1 after the cat. the one before the cat appears to be critical to set mixture, so check or replace that one first

1997 breeze is shooting codes 12 46 43 55


OBD Code 12 - No Distributor Reference Pulse (Diagnostic Test Active) The Engine Control Module-ECM uses the distributor reference pulse to calculate the engine speed. On newer engines, the Crank Shaft Position Sensor performs this function.

Symptoms:
  • When flashing the Check Engine Light to read codes, code 12 will always display first, indicating the diagnostic system is active
  • The engine will not run with a "hard" code 12 set
Common Problems:
  • Chances are you will never need to diagnose a code 12. Rather, the problem would be a crank, no-start condition.
  • If code 12 does not flash, that would indicate a communication problem with the ECM.
  • Code 12 does not show when reading codes with a scan tool. If there is a communication problem, the scan tool will let you know.



OBD Code 46 - Pass-Key II System Error - Circuit out of Frequency Range The ECM receives a signal from the Pass-Key module. When the correct signal is received, the ECM will allow the engine to start and run. Please review the RepairPal article on the GM Pass-Key Anti-theft systems for more information.

Symptoms:
  • Engine may not start
Common Problems:
  • Faulty ignition lock cylinder



OBD Code 43 - Knock Sensor error The ECM receives a signal from the Knock Sensor based on the amount of engine ping detected. The ECM uses information from this sensor to help calculate fuel delivery and spark timing.

Symptoms:
  • Engine ping
  • Lack of power
Common Problems:
  • Faulty Knock sensor
  • Poor connection at Knock sensor


OBD Code 55 - End Test.


Hope ehit help (remember comment and rated this).

Hello. You have posted an excellent question.

The code 55 you are getting, in Toyota terms, as as follows:

"No number one knock sensor signal to the ECU fo four crank revulutions under these 2 conditions: Coolant temperature 140 degrees F or more; Engine speed between 1600 and 5200 RPM."

This indicates a failed (or a loose) knock sensor on the Right Bank of the engine. Since the knock sensor is basically a piezo-electric crystal, not continuity test can be performed with the intake manifold installed.

You can check the continuity form the Knock Sensor wires to the ECM, but, this may not prove useful to you.

Unfortunately, you are going to have to pull the intake, and check the knock sensor wiring integrity. If the connector is good, and the sensor is tight, I would suggest replacing the sensor. Actually, if you were in my shop, I would suggest replacing them both, as the whole intake will have to come off if the other sensor fails. Better to replace them both at once, than to pull the intake again.

We here at FixYa hope that this helps you out, and saves you some future reoair dollars. Thanks for choosing FixYa for advice.

Engine surge at 45-55 mph on 2002 Silverado 5.3l engine


I would start looking for a vacuum leak. Check all the vacuum lines for cracks or breakage. Spray penetrating fluid on them until you hear the engine start to stumble then focus the spray on that area until you are able to pinpoint the location of the leak. Best of luck,my friend, Dana

ABS brakes shudder


YOU NEED A SCANNER TO MONITOR THE WHEEL SPEED SENSORS. THE ABS IS SENSING A SKID AND THE ABS IS ACTIVATED WHEN THIS HAPPENS. THERE MAY BE A CODE FOR THE HUB THAT IS CAUSING THE ABS TO ACTIVATE.

CHECK THE WIRES FROM THE SENSORS FOR BREAKS OR CHAFFING. AN OHM READING OF THE SENSOR SHOULD BE 850-1200 OHMS, AND AND A-C VOLTAGE READING SHOULD BE 100 MV WITH YOU TURNING THE WHEEL BY HAND.
