Honda CR-V. Ignition System

Ignition Timing Inspection

1. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC).

2. Turn the ignition switch ON (II).

3. Make sure the HDS communicates with the vehicle and the powertrain control module (PCM). If it doesn't communicate, troubleshoot the DLC circuit.

4. Start the engine. Hold the engine speed at 3,000 rpm without load (Park or neutral) until the radiator fan comes on, then let it idle.

5. Check the idle speed.

6. Jump the SCS line with the HDS.

7. Connect the timing light to the service loop (white tape).

8. Aim the light toward the pointer (A) on the cam chain case. Check the ignition timing under a no load condition (headlights, blower fan, rear window defogger, and air conditioner are turned off).

Ignition Timing:

8 º +- 2 º BTDC (RED mark (B) ) at idle in P or N position

9. If the ignition timing differs from the specification, check the cam timing. If the cam timing is OK, update the PCM, if it does not have the latest software, or substitute a known-good PCM, then recheck. If the system works properly, and the PCM was substituted, replace the original PCM.

10. Disconnect the HDS and the timing light.

Ignition Coil Removal/Installation

1. Remove the ignition coil cover (A), disconnect the ignition coil connectors (B), then remove the ignition coils (C).

2. Install the ignition coils in the reverse order of removal.

Spark Plug Inspection

1. Remove the spark plugs, and inspect the electrodes and ceramic insulator.

2. If the spark plug electrode is dirty or contaminated, clean the electrode with a plug cleaner.


3. Replace the plug at the specified interval, or if the center electrode is rounded (A), or if the spark plug gap (B) is out of specification. Use only the listed spark plugs.

NOTE: Do not adjust the gap of iridium tip plugs.

4. Apply a small amount of anti-seize compound to the plug threads, and screw the plugs into the cylinder head, finger-tight. Then torque them to 18 N*m (1.8 kgf*m, 13Ibf*ft).


 Charging System


 Charging System Indicator Circuit Troubleshooting

1. Turn the ignition switch ON (II). Does the charging system indicator come on? YES-Go to step 2. NO-Go to step 14. 2. Start the engine. Hold the engine speed at 2,000 rpm for 1 minute. Does the c

 Alternator and Regulator Circuit Troubleshooting

1. Make sure the battery connections are good and the battery is sufficiently charged. 2. Connect a VAT-40 (or equivalent tester), and turn the selector switch to position 1 (starting). 3. Start the


 Second Row In-Floor Storage Bin - If Equipped

In-floor storage bins are located in front of the second row seats and can be used for extra storage. The storage bins have removable liners that can be easily removed for cleaning. In-Floor Storage Bin And Latch To open in-floor storage bin, lift upward on the handle of the latch and open the lid.

 DTC P2122: Accelerator Pedal Position (APP) Sensor A (Throttle Position Sensor D) Circuit Low Voltage Input

NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information. 1. Clear the DTC with the HDS. 2. Turn the ignition switch ON. 3. Check whether DTC P2122 is indicated in the DTCs/ Freeze Data in PGM-FI Mode Menu with the HDS. Is D
