1. Carefully check each knock sensor wire coming from Engine Control Module (ECM). Measure resistance [in Ohm] for each knock sensor wire, both connection plugs removed, (one plug from knock sensor, and another one from ECM). Put one multimeter lead to one wire end pin, and second multimeter lead to another end of the same wire. You should read low resistance values on the multimeter screen, for example 5 ... 8 Ohm. Also check the insulation (resistance) in raport to plus battery, to chassis ground, and between wires. Repair damaged wire(s) if necessary.
2. If all knock sensor wires coming from Engine Control Module (ECM) are in good condition, and you have been replaced the knock sensor with a new one, the ECM is bad and needs to be replaced because still keep getting the same code #52.

    there is only 3 things that can cause this code, 1st the knock sensor and you stated that you replaced it, 2nd the wiring from the EMC to the knock sensor, check for contenuity from the knock sensor wire to #4 pin at the ECM if there is contenuity replace the ECM.....good luck

Rewire the section of wire between the knock sensors & the ECU with shielded coaxial cable. Look for multi-stranded ~50 Ohm 18 to 22AWG specs, which can normally be found by hitting the computer supply store for 10Base2 cable [RG58], often referred to as Thin-net cable. Get 8' of cable for the rearward sensor, & 10' for the forward sensor- this will be plenty to work with. Side note: Some folks have gotten away with using D3 [RG59] cable, but be advised that it is rated at 75 Ohms. A few have even done the rewire with solid core coax, but you don't need me to tell you that isn't a great idea.

Anyway, the use of this shielded cable has proven to resolve a recurring Code 52, where regular wire can't. Sorry, I don't know more of the technical specifics, & in this case, I just took the word of several respected SOGI members who'd done this in the past. Hypothesis indicates that the signal is subject to RF and/or EMI interference, hence the shielding.

Can you tell me the location of code reader 1991 capri ?


1991 is pre-OBD2. code readers will not work.
sorry.
however, all is not lost. Many cars have an alternate way of reading codes from the computer.
Toyota has a block under the hood and you short couple wires together and count engine light flashes
Chrysler you can turn the ignition key on and off a few times and count engine light flashes
in your case for GMs from 1982 to 1995
1: find the 12 pin connector under the dash and short the upper two rightmost terminals.
with the ignition "ON" and engine not running. The system will enter the diagnostic mode. In this mode, the computer will display a Code 12, three consecutive times, by flashing the "CHECK ENGINE", "SERVICE ENGINE SOON" or "MALFUNCTION INDICATOR LAMP" or light. A Code 12 consists of one flash, a short pause, then two flashes in rapid succession.
2:. After Code 12 is displayed, any stored trouble codes will be displayed by flashing the "CHECK ENGINE", "SERVICE ENGINE SOON" or "MALFUNCTION INDICATOR LAMP" light. All codes are displayed 3 times each then a code 12 will repeat. In the diagnostic mode, the computer will also energize all computer controlled relays and solenoids.

WHERE IS THE KNOCK SENSOR ON A 2006 CHEVY COBALT TO REPLACE IT.


Not related to the O2 sensor. Located on the front of the engine just above the starter KNOCK SENSOR (KS) SYSTEM DESCRIPTION

PURPOSE
The knock sensor (KS) system enables the engine control module (ECM) to control the ignition timing for the best possible performance while protecting the engine from potentially damaging levels of detonation. The ECM uses the KS system to test for abnormal engine noise that may indicate detonation, also known as spark knock.

SENSOR DESCRIPTION
The knock sensor (KS) system uses a flat response 2-wire sensor. The sensor uses piezo-electric crystal technology that produces an AC voltage signal of varying amplitude and frequency based on the engine vibration, or noise, level. The amplitude and frequency are dependant upon the level of knock that the KS detects. The engine control module (ECM) receives the KS signal through a signal circuit. The KS ground is supplied by the ECM through a low reference circuit.

The ECM learns a minimum noise level, or background noise, at idle from the KS and uses calibrated values for the rest of the RPM range. The ECM uses the minimum noise level to calculate a noise channel. A normal KS signal will ride within the noise channel. As engine speed and load change, the noise channel upper and lower parameters will change to accommodate the KS signal, keeping the signal within the channel. In order to determine which cylinders are knocking, the ECM only uses KS signal information when each cylinder is near top dead center (TDC) of the firing stroke. If knock is present, the signal will range outside of the noise channel.

If the ECM has determined that knock is present, it will ****** the ignition timing to attempt to eliminate the knock. The ECM will always try to work back to a zero compensation level, or no spark ******. An abnormal KS signal will stay outside of the noise channel or will not be present. KS diagnostics are calibrated to detect faults with the KS circuitry inside the ECM, the KS wiring, the KS voltage output, or constant noise from an outside influence such as a loose/damaged component or excessive engine mechanical noise.

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.

The above link is to a diagram of your ALDL connector, all you need is a paper clip, straighten out the paper clip and insert one end into the diagnostic test pin and one in the system ground pin (terminals A & B).

Then put the key in the ignition and turn it to the on position but DO NOT start the engine. You will then see the check engine light flash. It will initially start by flashing once, then a pause and then flash twice and it will repeat this three times. That flash sequence indicates 12, which just means the system is operating. Its the flash sequences after that that will give you the code if any are stored.

For instance if it flashes twice, then pauses, then flashes four times, thats code 24. So any flash sequence you get after the initial 12 (flash once, pause, flash twice) you need write those down. Below is a list of diagnostic codes to tell you what the codes mean.

Code 12
1 flash, pause, 2 flashes
Diagnostic: This Code will flash whenever the diagnostic terminal is grounded with the ignition switch turned on and the engine is not running.

Code 15
1 flash, pause, 5 flashes
Coolant Sensor Circuit (low temperature) Coolant temperature sensor signal indicates a temperature colder than -36° F for at least 4 seconds after the engine had been running for 2 seconds. See above, then check wiring connections at the ECM

Code 16
1 flash, pause, 6 flashes
Charging system voltage was either below 9 volts or above 17 volts for 10 seconds. System High Voltage If the voltage is above 17.1 volts for more than 2 seconds, the Service Engine Soon light will illuminate. Have the charging system checked.

Code 17

Or vehicle speed goes from above 18 MPH to 0 in less than 2 seconds without applying brake. This code can only appear when the vehicle is in motion, if it appears when the car is not in motion, ignore it. Check ECM connections, any other problems should be diagnosed by a qualified mechanic.

Code 25
2 flashes, pause, 5 flashes
Inlet air temperature sensor signal showed an air temperature of over 218° F for 5 seconds when vehicle speed was greater than 35 MPH. Check the voltage between the MAT sensor and the ECM. voltage should be above 4 volts.
